Synthetic Urine Is The Best Way To Pass A Drug Test

synthetic urineSynthetic urine is the best way to pass a drug test. That’s because synthetic urine aka fake piss is the same stuff that drug test labs use to test and calibrate their equipment. Sure you could try a detox drink to mask your urine or take a detox pill that’ll work in a few days, but why alter your body chemistry if you don’t have to?

Synthetic urine is easy to obtain. We recommend Sub-Solution synthetic urine but there are several fake pee brands on the market. We suggests buying liquid urine not the powdered stuff and dig brands that include a heating powder because handing over a cold urine sample is a surefire way to fail the test. Also make sure that you purchase synthetic urine that hasn’t gone beyond it’s expiration date. And always make sure that whatever synthetic urine you purchase is authentic—not counterfeit. We’ve heard of plenty of counterfeit Quick Fix synthetic urine on the market.

Check out our post on how to pass a drug test for information on using synthetic urine and a few other solutions. If you’ve used artificial urine to pass a drug test let us know in the comments section below.

    I just wanted to leave my feedback/review for anyone out there considering using fake urine for a drug screen or who is looking to see what actually works. Based off the reccomendations, I used sub solution synthetic urine. I ordered it right from their website, got here in like 2 days, in a non suspicious package. Read the instructions multiple times, and brought everything with me. Outside the drug test center (concentra), while I was still in my car, I pre mixed the urine powder and water in the squirt bottle with the temperature reading, since you can do that up to 8 hours before the test, just so I had less to do in the actual drug testing bathroom (less chance of getting caught). So I put the squirt small sized bottle that contained the urine powder and water mixture in my bra on one side, temperature strip away from my skin, and the small bottle of the heat activating powder in my bra on the other side. They gave me the cup to go in, and sent me into the bathroom unsupervised, but he was right outside the door. They tell you not to flush the toilet, and you do not have access to a sink in the bathroom, you can’t wash your hands until after you come out with you sample (so make sure you have the water you need to mix the urine prior already in the mixing bottle like I did). Once I got in there I simply shook up the urine and water mixture gently a little more, then poured about 1/3 of the heat activator in and shook it up. You could feel it get hot and clearly see the temperature of it on the bottles temperature strip. I actually made mine a little too hot, so I laid it down on the coldest surface (the back top of the toilet) temperature strip side up to cool down a little bit for a breif 30 seconds or so. Once it hit 98 degrees, I just squirted the mixture into the urine cup that the testing center gave me, and at this time also really urinated in the toilet at the same time because urine hitting a toilet full of water and a liquid being squirted into a little cup just doesn’t sound the same, and I didn’t want anything to be suspicious. Also, it’d be weird if there wasn’t anything urine looking in the toilet at all, and they don’t test what’s in the toilet so it didn’t matter that I myself actually urinated in the toilet anyway.
    After I filled up the specimen cup with the synthetic urine I put the lid on it, finished my business on the toilet, and put the containers or the fake urine and heat activator back in my bra. (DONT DUMP THE EXTRA FAKE URINE IN THE TOILET, IT MAY TURN THE WATER BLUE TIPPING THEM OFF!)
    So I exited the bathroom after a total time of maybe 2.5-3 minutes (an acceptable amount of bathroom time, esp for girls) and handed the man the the specimen cup with my fake urine sample.
    He checked the temperature, marked that it was correct, and sent it off to a lab. A few days later, I got called that I got the job!! So yes, sub solutions fake urine def works, and this was just recently in April 2016.

    1. If you know for sure you’re about to go into a drug test, pre mix the urine powder and water in the temperature reading mixing bottle it comes with out in your car first. It’s one less container to carry, and one less step you have to do while under pressure and time constraints. You have up to 8 hours to use it once you mix it with water.
    2. You need way less heat activator then you think you need, but it can cool down if you use too much like I did.
    3. Read the directions it comes with multiple times so you have them memorized so at the test you can just get it done quickly, errorless, and smoothly.
    4. Try to keep the bottles and stuff quite when handling them in the bathroom during testing! I dropped the lid of mine in the bathroom with a guy standing right outside, it was so loud hitting the floor! Luckily my guy didn’t say anything, but still be careful!

    Congratulation Rose!!!!!!

  3. Steve

    Great comments on the sub solutions; however, my concern is with the 8 hour window. What if they send it to a lab and don’t test it for 12 hours? Can it settle?
    That said, I’m leaning towards quick fix 6.1 as it has a 2 year shelf life (though sub solutions and purine more closely resemble actual piss).

  4. Kelly

    Can you use catheter to inject fake urine.

  5. Anonymous

    Rose your awesome for the comment I just need to google the shelf life if the lab they send it to don’t test it right away but ty lol and congrats

  6. Carl

    Has anyone taken a random drug test at their job? How would have time to mix everything?

  7. Jsmoove

    I just used sub solution yesterday and passed and got the job it really works

  8. Jsmoove

    Pre employment unsupervised rose nailed it same for dudes just lodge that container under your junk

  9. Cook_chilli

    What to do about urine screen supervised like probation? Thank you for the info. PEACE!!!

  10. Cat

    Hi! I’m facing a DT tomorrow morning and just purchased P-Sure synthetic urine. Does anyone have any experience or tips with this product they can share? Much appreciated if so! Thank you

  11. Dave

    Just took my DT. The collector took my cup, dipped it, then smelled it and said it doesn’t have a smell and she can’t submit this. Is that legal?

  12. RG

    I supposed I should start by saying I am a real person who was EXTREMELY worried about an upcoming 10 panel urinalysis drug screening I needed to complete in order to start clinicals at the hospital. This review is going to be lengthy as I wish I would have read one with as much information when I was going nuts. I quit smoking completely on May 23rd 2016 after a weeklong trip to Colorado in which I smoked many flowers and ate countless edibles. Prior to Colorado, I had smoked pretty much everyday, several times a day. When I’ve quit in the past, it has taken me a good 6 weeks to test clean so I knew I would not have enough time for the upcoming test with LabCorp on June 17th. I decided to purchase Clear Choice Sub-Solution Synthetic Urine from after reading every review I could find online. Yes, it was more expensive that the Quick Fix, but I figured this is not something you skimp on, especially with as much as I had to lose. I received the product and read the instructions so many times, I could practically recite them from memory. The day of the test, I arrived at LabCorp with the bottle and heat activator nestled snuggly in my gooch area. Make sure you practice this prior to going so that you can make sure you can walk and move around freely without fear of anything slipping out or looking like you crapped your pants. The technician at the lab asked me to wash my hands and led me to a regular bathroom with a sink and toilet. He told me to do my business and leave the specimen cup on the counter once I was done. It was unsupervised and he did not wait outside the door. I opened the cap off the bottle and sprinkled a small amount of the heat activator into the bottle. I could feel it get warm in my hands and verified it was within the acceptable range of 98 to 100 degrees with the temperature strip. Once I was done, a girl at the front asked me to wait as she was not sure if I had submitted enough “urine” for the required test. At this point, I was kind of scared because I obviously did not have any more urine to give, at least not any of the good stuff. After some quick praying, another tech came back and said I was good to go. I went to my car and used a THC dip stick drug test I had purchased with a couple of drops that were left in the bottle. It immediately showed that it was negative, which was somewhat of a relief. I waited two business days and called my doctor’s office to see if the results had arrived and played it off as I needed them for school. They told me they had and the doctor would call me later as they could not give them over the phone. A short while later, I received an email from my doctor’s office with the lab report and everything was NEGATIVE!!!! The immediate relief I felt was amazing. Needless to say, I had my doubts even though every review I read said it worked. Nothing beats having a paper in your hand stating you’re clean! If you have any doubts, please rest assured that this stuff works. My future depended on this stuff and it did not let me down. Good luck to everyone!

  13. Mark

    Its not listed here, but Ive used Ultra Pure urine made by Ultra Klean twice and its passed everytime. Just thought that should be mentioned since I dont see anything about that kind of fake pee listed here. Thanks for the info guys…

  14. Illmaticnooder

    Carl,you need something like u pass or clean stream for a random test at work….clean stream has a big bladder bag with a waist band and temp strip on the front takes a while to heat cuz it’s 5 oz but put your heat pad on it and it will get up to body temp in bout two hours so just walk around with it on….”I worked in a wearhouse setting n mine didn’t break or anything or use a soxk and cut a slit in it attach it to your belt n let it sit down in your pants under your nuts..even if someones outside the door just grab the squirt cap n squirt into the sample cup….good luck bro

  15. The Wizard of Id

    I, like most of you, was freaking out over not being clean and the effectiveness of using a synthetic urine. Every post seemed to be filled with uncertainty and raised even more questions. Let me definitively tell you that in my case, Sub Solution worked. I pre-mixed it before going to the testing site, hid it in my pants and put a tiny bit of the heat activator in while pissing into the toilet. It works.

  16. jhash

    Had a ua test and needed the synthetic urine. So I bought the sub solution and passed no problem. Will work if keep calm and keep temp up above 90 degrees which is very east if kept in crouch it stays just about 96-97 degrees for over hour maybe longer. Read the worst part was the worring and read so many articles. Would have to say practice practice before and be careful lid does make bit of noise when in small silent bathroom. Didnt even pee in toilet just dumped it into cup and told him that is all i got sorry……… Less than a week got call got job….. Thanks sub solution……….

  17. Ale

    Has anyone tried it to pass with cps I tried with ultra in a yellow box and the results are taking forever should I be worried or will it pass

  18. Chris

    I was freaking out and read so many reviews and articles on synthetic urine for my pre employment.

    I went with Quick Pass, and it worked!

    Hardest part was sneaking it in, I taped it on my pube areas and wore tight undies and was good.

    I was concerned with the smell but I guess that didn’t matter

  19. John

    Steve, Did you end up going with Quick Fix or Sub Solution? Did you have any luck?

  20. Read Me Ladies

    Just a little hint for the ladies who have supervised drug screens. Use a 5 Hour Energy bottle, make sure you clean out very well. Fill with the appropriate amount of liquid that you need for your test, cover opening with foil and wrap very tightly around opening with rubber band. This will create an area for you to easily puncture with your fingernail when it’s time to give your sample. Just insert before you go to your testing facility and when you have to give your sample, simply puncture the foil with your nail and fill the specimen cup. It’s that eaay.

  21. Dai Dai

    It ABSOLUTELY WORKED! Got the job I desperately needed!! Spend the extra cash, follow directions, and stay blowing on those trees!! Good luck Fam!

  22. Silver haze

    I just used a different brand of syn piss called ultimate gold on 7/20/16. Just got called and start tomorrow. I was also in the boat of wondering if syn piss would work. First time user of it.

  23. To "Read Me Ladies"

    That idea is Genius. I’ve been wondering what to do.

  24. Darryl

    I confirm that Sub Solution absolutely still works as of July 2016. You can rest easy knowing that, despite the cost, you’ll definitely pass your piss test.

  25. Martin

    These are mostly fake comments from people who never used this FAKE solution. It DOES NOT WORK at Quest labs! Just got a call to say I failed thanks for nothing sub solution. (Btw I used the product perfectly and the temperature was correct your product is just a scam)

  26. Am I doomed?

    So I took a urine screen with XStream yesterday. Have never taken a fake urine screen have always been honest. However, I was a bit skeptical that I may not pass. Being my first time and no one told me other wise, apparently they use something now that turns the toilet water blue if you use fake urine. Because I was new to this I dumped the fake urine in the toilet and it turned a very light blue. I haven’t received the call yet that I failed due to it being tampered or fake, but pretty sure I will. Now am trying to figure out if I will be able to talk my hiring agency for a job that I really want, into letting me take another immediately, I will pay and have it supervised to show that I am clean. Pretty sure I can pass. Very light smoker only once of twice on weekends and has been 10 days. Any advice?

  27. bob

    Will any of these products work for a lab test? If i loose my job i will seriously find and murder you for telling me the wrong thing

  28. Darryl

    I’m not fake, but I did have my test at Labcorp, not Quest. Sub Solutuon worked there.

  29. Blank man

    Hope this stuff works. I’ve heard many good reviews but have heard that they are on to sub solution now too. I will be finding out soon enough since it just came in the mail today. My test will be at LabCorp for a job. Just want to smoke and not worry, smh.

  30. bob

    Thanks but no thanks….im not going to risk my good job to smoke some weed and rely on some sketchy posts claiming this stuff works. Maybe it will pass a bullshit drug test for a job at bestbuy or jiffylube but i wouldnt trust this for a dot test sent to a lab….its not worth it

  31. Darryl

    You’ll be fine, Blank man. Mine was for a really good job. They sent in to the lab for testing (not instant testing), and I passed.

  32. Keisha

    I need help…..Does this stuff really work….I’ve been out of work Since April and I have an interview for a job that I really want. I smoke daily ( a lot) and I need help with passing a DT. HELP!!!!!!!!!!!!!!!!

  33. Scott

    I used sub solution for my pre employment screening today and passed. I would recomend this product to any one, its great!!! Thanks so much for the info above! It helped me immensely!
    Its easy to use and works great.

  34. Cheesehead420

    So I wanted to post about my experience getting drug tested for a new job, that was VERY important for my career. In the original brochure, drug testing was mentioned as a prerequisite. The first thing I did was buy a xstream synthetic urine kit from Amazon because it had good reviews and was cheap ($13). Then, after thoroughly researching different brands and reading others’ reviews countless times, I decided to purchase sub solution as well. I really liked the idea that the powder can get it heated up to temp instantly, and I had not seen any other brands that offered this. It also had what I considered to be the best reviews on several sites. Spending 75+shipping seemed expensive, but if it could guarantee that I would pass, any amount of money was worth that to me. This kit also claimed to pass the validity tests for urine (ph, specific gravity, creatinine(NOT CREATINE, these are not the same), uric acid, urea, etc).

    My original plan was to quit completely, but with moving to a new state and all my other stressors, this proved too difficult to follow through with. I have been a daily smoker (multiple times a day) for 15 years…God knows how long it would have taken me to detox naturally, too long to pass! So I also had ruled out detox drinks for this same reason- they only appear to work for people who are occasional users. However, a friend used this method which I will review below for everyone’s benefit.

    So, the company who hired me runs a background test, which I pass, and never brings up the drug test again. So here I’m thinking, “sweet! Don’t even have to worry about this!” I go in for my first day, complete all the paperwork for HR, and still no mention of the drug test. So now I’m convinced I’m Scott free. After lunch, an employee tells me to head back to HR. So I head there, to find out SURPRISE I have a drug test! And she’s called the center to tell them I’ll be right over. Now, I don’t have either synthetic urine with me because I had gone over the options multiple times and I never expected to be asked to do it the first day. It’s PRE-employment! So I shit a brick because I know my actual urine would never pass and that using an adulterant is a great way to get caught. Fortunately, I had time to run back to my house, grab the sub solution, and run back to the testing place. At my house, I read the instructions and mixed the water with the powdered urine in the container that came with it. That mixed fine with no clumping (directions said to put the powder in first I believe, so follow the directions!) I also put on a bathing suit bottom over my underwear, and put the bottle between my undies and my bathing suit bottom between my legs. I put the temperature strip away from my body, and made sure I could walk ok. My pants were fairly tight, but I couldn’t change them or else that would have been a dead giveaway that I went home. I raced back to the testing center. Even without the powder to heat it up, the urine was at 94 degrees according to the bottle (checked in the parking lot). It was a hot day out (close to 100) and I was sweating bullets, so this probably helped keep it at temp. I put the heating powder in my bra, because I thought they would have me empty my pockets. Turns out, this girl leads me back to a regular bathroom (working sink, no blue coloring in the toilet) and lets me take my purse and doesn’t ask for me to empty my pockets! I was dressed professionally and trying to act as nonchalant as possible. The bathroom also had a vent fan going which made me less nervous about making noise shaking up the urine. Talk about ideal conditions! I took the urine out and the temp had dropped to close to 90. I added a TINY bit of the powder since it was already so close and got it back to 94. I poured it in the cup and the temp strip on their urine specimen cup looked like it was too low (under 90). So I added more powder to the actual urine cup and swirled it around. You could instantly feel it heat up. It was back up to temp, so I put my stuff away and rushed to give it to her so it didn’t lose any heat. She read the strip and checked the box that it was the right temp (between 90 and 100). It definitely looked like urine with the foam, but I didn’t notice a urine smell. However, I was also freaking the fuck out so I wasn’t sitting around sniffing it. She had me initial two smaller test tubes she divided it into, and threw away the rest! I was like…nooo! That’s expensive urine (in my head lol)! I felt pretty good about using the fake urine- it was clearly the best alternative!

    The next 10 days were hell! I kept googling online how long it takes to hear back from a drug test (my testing was not done at the collection facility, it was shipped somewhere) and I had read it could be over a week if it was positive. However, the company’s website said that kind of test would take 1-3 days to get the results. The receipt I had been given identified the type of test they gave (9 panel WITHOUT ph/oxidants). I Googled the test model number to find this out. I also figured out that this meant they were only testing for the presence of drugs, not actually testing to see if the urine was real. Since most sites report that urine is only subbed/adulterated about 5% of the time, it probably wasn’t worth it for my new job to shell out extra money. Not to mention they snuck it up on me! This made me feel better, for a day, but I was still really freaked out. I was waiting from an email or visit from HR saying they had to terminate me. I kept thinking “what if the lab tech suggests extra testing for validity?” Or some crazy exception along those lines. This is the downside of not just sobering up naturally! But I just had to fake it like everything was cool. Turns out most labs test up to 15000 samples a day, and some more. A person is not personally conducting each test, a computer is and a person (medical review officer) is verifying that the computer was right.

    So now I feel safe to say that I have passed using SUB solution! I am probably going to buy another one to have on hand. The nice thing is that it is not premixed so you can store it anywhere. I still wonder if it truly would have passed if my company had ordered the validity tests…so I can’t help anyone with that part!

    Now, on to my friends experience with QCarbo32 detox drink. My other friend, John, claims he uses this drink each month to pass his drug test for his parole officer. John smokes once a day a very small amount to help keep his thc metabolites low. So I passed on this information to Val, my other friend. She is an extremely occassional smoker, but she was in Colorado 3 weeks before the test, smoking and eating edibles nonstop for 4 days. And then 3 days before her test she took ecstasy (she knew the test was coming…not the best idea!) So she follows his instructions (the same as the bottle) to drink the morning of, drink a lot of water, pee a few times and then go. She said, as others have said that her pee was neon green practically, and was still pretty bright by the time she peed for the test (hers was at quest. Mine was not at a chain). So whatever, she’s done. Less than 48 hours later she hears back from the HR lady saying “we have a problem” (my nightmare!!!) And that the sample was “Too dilute” to be able to render a valid result. So, her company clearly did spring for the validity testing. The HR lady told her she had to take ANOTHER test the next morning or they wouldn’t hire her.(side note: my friend Kim said that her sister had failed a drug test for the same reason even though she didn’t use drugs. The people told her not to drink so much water and to be retested. So this DOES happen for legit reasons) Val had already passed home tests for thc the week before, and by this time the ecstasy was out of her system (it had been 5 full days). So I told her she should use her own piss at this point since she had been testing negative and isn’t a regular user. So far, so good for her! It has been 3 days since the test and she has started work. Considering how quickly she heard back from the HR lady last time, I would say she’s in the clear as well. So, my conclusion is that I would not recommend using ANY detox drink or dilution method. They can measure dilution using specific gravity AND creatinine and I don’t think a cheap drink will fool machines. My buddy on parole does a test where it says on the cup if he passed or not, so he actually has easier drug tests than people just trying to secure a job! SMH. Pre-employment drug testing is illegal in canada. For a reason! They have no probable cause!

    Lastly, let me add another buddy’s story, my friend bob. Bob had originally recommended to me to use quick fix synthetic urine. He said that he and all his friends had used this on all their Pre-employment tests and always passed. I told him that I saw some mixed reviews online and that I wasn’t considering using this. I also told him that I had seen some reviewers say it came back failed because it was detected as “non-human specimen”. He insisted it worked. Well I heard from a mutual friend after telling her about my surprise drug test story, and she said that Bob’s dad had lost a job offer from using quick fix! It had come back failed because it was “non-human specimen”! And this had been a really good opportunity for him. So yeah, it sounds like quick fix will NOT pass the validity tests.

    I want to thank everyone brave enough to write a review about these products! The Internet has saved me again and again in this predicament, and it is because of people like you! Please, if you post asking questions or giving your own story (without the results), make sure to post what actually happened (did you pass?!). It is only fair. People took time to soothe your anxiety and answer your questions, the least you can do is return the favor. I am going to copy and paste this review onto multiple sites to help spread my experiences. So if you see it, please know it’s a real review. I wouldn’t have typed ALL this if it wasn’t. Best of luck to my fellow stoners. Break the stereotype: get good jobs and become successful and hopefully 20 years (or sooner!) From now we can change these arcane policies. Drug tests discriminate against stoners! Don’t let anyone tell you anything else. Check out California’s NORML site for detailed info on drug testing, detox times, and other important info.

    My experience at Labcorp and yes I am a real person and sorry this post is long but I researched and worried a lot over passing my pre-employment drug test… So this is for the other people who are facing the same situation. So I have been a heavy every day smoker for about 10 years now. I hated the job I was working it was retail management and I wanted something with a set schedule Monday through Friday. Along with something a little less stressful. I don’t care if you say you should have stopped smoking because the situation came so fast and I wasn’t going to pass on the opportunity. I wasn’t really looking for a job but one day I came home from work and was so upset about the way I was treated I went on Craigslist and started sending out my résumé. What do you know two days later I got a call for an interview and I ended up getting the job. The interview was really relaxed and so was the office. I mean real relaxed people were wearing sweatpants in the office! I never thought they would drug test and I took the job. A week later the staffing agencie told me I had to take a test. I was freaked out! So my only real option was to sub with some synthetic urine. Anyway so after doing all my research and searching through forum after forum I decided to use sub soliton which I got off testnegitive. I followed the instructions made the mixture but I didn’t want an extra step with the heat activator so I could spend as little time in the bathroom as possible. So I used a to-go back warmer and stuck it to the inside of my jeans where it wouldn’t be on the bottle directly since I didn’t want to put a warmer on the bottle (I heard it can make it too hot). Anyway because I’m female I put on two pairs of undies so I know it would be secure and I just put it in my panties like a pad, temp strip away from the skin. I left for the lab right away. It was about a half hour drive and by the time I got there it was perfect temp right at 98. I went in and since I had an appointment I only waited about 10 mins. This is the key part where you don’t want to get nervous. There was one person in front of me but he was like pacing in the waiting room and getting upset he had to wait. I wasn’t surprised they called me first. I was a little nervous but I was focused on my breathing and counts of four. It sounds over the top but it really calmed me down and I was hardly nervous. So the nurse had me grab a cup and explained I had to fill the cup right above the strip on the cup and had me put all my belongings in a locker. She sent me into the bathroom alone and instructed me not to flush the toilet or wash my hands. She also threw this blue tablet into the toilet I imagine this is so you can’t use the water in the toilet to dilute your sample. Once I was in there I super quickly checked the temp it was still at 98 and I poured it into the cup. I didn’t even use half the bottle. It sounded like a bottle when I was squeezing it so I didn’t want to use any more and peed into the toilet. Don’t worry they don’t test the toilet water. Also make sure even if you don’t really pee to throw some tissue in the toilet. I was in the bathroom maybe a minute. When I came out she had me set it down on the counter and had me watch her pour it into a small sample bottle. She sealed it and then went into the bathroom looked into the toilet and poured the leftover “pee” in toilet and flushes. She had me sign two papers and the sealed sample. On the paper she didn’t leave any comments and circled that it was the right temp. I left never heard back from them and started my new job in less then a week. Welcome to the sub club. My main advice stay calm and don’t worry about it: it’s simple and it works. Thanks sub-solution ;]

  36. AnxietyKiller

    Used sub solution @ Quest in Oregon. August 11th. Passed. Researched every top brand and bought 3 different kinds, ended up going with sub solution after the reviews and intense research. Thank you Lord!

  37. Justin

    Does sub solution work if the synthetic sample has been mixed for a few weeks? Also does the heat activator work on real urine? If you use someones clean urine how long before it goes bad (stale) and wont pass?

  38. James

    Completely off subject but a question I need answered! I have to take random drug tests (5 panel and ETG) for diversion. I have to take them at a place where they do not watch nor do the testing. The urine gets mailed to a lab through express mail. I have frozen 100% clean urine. I have read that when it thaws it is only good for 8 hours. I am wondering if anybody knows if I’ll be safe to use it, and that it will still be able to pass when it arrives at the lab the next day or two! What is the difference if I pee on the spot and it gets mailed and arrives in a day or two vs using thawed out pee to the correct temperature that will arrive in a day or two?

  39. Hector9000

    You should be fine. I did research on this as an alternative. Let it thaw, like you said, definitely don’t microwave it. There’s no difference between your actual pee or dethawed pee assuming it’s not more than a year old (this would be more of a risk). Just make sure it’s up to temp. The only reason why you need to use it within 8 hours is because real urine starts to grow bacteria after 8 hours and smell stale (read: super strong smell that’s hard to miss). However by the time it will be shipped to the lab I would imagine most samples had grown bacteria. Maybe they can measure the levels? That is my best guess.

  40. Cheesehead420

    @Justin I don’t think you should use it if it’s says once it is mixed you need to use it within 6 to 8 hours. Urine grows bacteria as the post above says. Definitely reinvest.

  41. Joe

    My friend passed a test at concentra in VA sent to quest diagnostics using clear choice sub solution on aug 25. was asked to empty pockets but checked no further. Practice with your Temps he was closer to 95 then 100 and was freaking out. The sheet says check if between 90 and 100 but the wrong tech may have made him go again can’t say for sure tho.He didn’t take the heating powder in with him just used to heat it before the test luckily he dosent think the tech even really look at it. He bought the leg strap clear choice sells but did not feel comfortable using it after practicing. Made a small bag using a sock. Used some string and looped it around his pants button so it hung right in front of his crotch and was super accessible. pulled the whole thing off before he even finished actually pissing in in the toilet. This may of been why the tech had no suspicion that something might be up and barely looked at the sample. If he tried to add more heating powder in the bathroom it would of taken substantially longer and probably caused more scrutiny of the sample. His advice practice practice practice and more practice. Practice keeping your Temps and get an idea of how much it will change over how long, just use some water in the supplied container. The leg strap seemed to keep temp better. Practice the delivery of the sample in to a cup as quickly and quietly as possible. Practice wearing your transport system so to not look awkward when walking or siting. In the future he will probably practice with hand warmers to keep the sample at temp, and only use the heating powder if temp is substantially off right before delivery. I hope this helps somebody. Drug tests suck

    Used sub solution yesterday and recieved my job offer today. It works!

  43. Just me

    So I am a female obviously and currently on probation I take random drug tests twice a month and smoke often although I have not used the synthetic urine yet I figured I’d give the ladies some adevice, If you are having a supervised test at all your best bet is to get a small container like the 5 hour energy or what I use is a small liquid medicine bottle that I hadon’t received from the pharmacy rinse the container out very well and let dry I’ve always used someone else’s clean pee but whatever it is that you choose to use this will work. First warm up the pee a bit I place my zip lock baggie with pee in at and put it in a bowl with semi-hot water”no need to worry about getting it to much warmer than room temp”, than I proceed to fill up the container and than i place a piece of foil over the top to replace the lid secure the foil with a rubber band I tear off the excess foil that hangs below where the rubber band is holding the “lid” in place, I than place the container in my vaJj laying down straight may be easier for you or you could do it as you would a tampon. While being placed in your VaJj it will keep the urine sample at a proper temperature. I like my little medicine container cause there is a bit of a neck on it that sticks out just enough for me to reach the foil with my pinky nail you may want to try and practice so you don’t look suspicious while being supervised. If any questions feel free to ask. Hope this information was helpful

    Can you reuse after you have opened up liquid pee?

  45. Susannah

    Ok wait a minute… if I understand this correctly, some testing sites use some substance in the toilet water that turns the water blue if one inadvertently (someone who didn’t know this) dumps any of the synthetic “pee” into the water. So, what’s stopping the person administering the test from deliberately dumping some of the sample “pee” back into the toilet, to see if it turns blue? I would think, since they’re using the substance to help detect fake samples, that this would be a real risk.

    What if you heated it up , and you didnt use it could I heat it up again and use it or is it done, cause I went to take a drug test and they said come back after the weekend I tried keeping it at 100° but it dropped can I still use it

  47. Jon

    What if you heated it up and then didn’t use . And it dropped to room temp, is it still good

  48. Chad

    In case anyone’s wondering the sub solution heat activator does work on real urine.

  49. Stink

    Most of these comments after Aug are idiots. I don’t believe any of them and neither should anyone looking at this page

    Has anyone ever use quick fix for a DOT job

  52. Older than b4

    I currently have a class A CDL and have to take a DOT drug screen randomly. I have used and will always use Quick Fix Plus. As long as you prep the temp you have nothing to worry. Inside each box of Quick Fix there is a green strip of paper w/ your bottles batch # on it. You can call Spectrum Labs with that batch # and they will confirm your batch.

  53. John

    Im in Canada and have a pre employment test. Does sub solution work in a split sample send away to a lab urine test? Or is it only good for the panel cups. I have quick fix plus 6.1 and sub solution. What should I do? It’s unsupervised and sent to a lab for testing

  54. Cheesehead420

    I’d say sub solution. I used it for a send away and passed. I think it is higher quality and more convenient because of the heating powder.

  55. Brian

    I’m on day 5 of the 10 day and still positive, so I got the synthetic just in case as backup since I don’t know when I’ll be tested, could be several weeks, am I being too impatient?

  56. Reply to-Just Me

    So my Friend has been doing the 5 hour energy bottle for a few years but the last ua she did she tested positive. Any idea why? We think a small amount of her urine got in to the cup. They have sent it of to the lab. She is on probation! what willl the lab say? I think that the concentration level will be low.

  57. Bigsteve

    OLDER THAN B4 I started with swift nov 14 and I havent smoked for awhile now about a month but I dont think ill be clean in time cause im a big dude . So you back quick fix plus 100% I’m nervous as hell but also need this job.

  58. Murphy

    Susannah; i am not completely positive on this part exactly, but from my understanding, the blue tablet in the toilet isn’t for detecting fake urine, they are putting dye into the toilet water you have access to so that you are not able to try and “dilute” your own urine sample with water out of the toilet. For the same reason you are not allowed to use the sink because you could be attempting to dilute the sample with the water. (If this were the case, I’d imagine they’d be putting a few drops of the tablet water into your actual urine sample you’ve submitted to confirm its validity).
    As for the Positive test from the 5hr energy bottle; these tests have >greater than 200nanograms>+) This is to account for the people who try to claim they were in a hotbox and never actually smoked the weed or the poppyseed muffin excuse that doesn’t fly either. That being said, I don’t think there’s any possible way that a drop or two would be enough to exceed those thresholds. I am certainly no Dr of course. I have a close friend of mine that was required to take UAs for both Federal probation officers and at an Outpatient treatment center as well. Her main treatment counselor was away on vacation for a few weeks resulting in a younger inexperienced counselor to fill-in temporarily. Somehow this incompetent replacement managed to report not just one, but TWO back to back positive results, one for cocaine and the other for morphine?! My poor friend was so confused and scared to potentially be facing the mandatory punishment for failing her treatment program.. the said counselor did report the results to her probation officer but somehow luck would have the PO believe in her story because she had coincidently taken negative drug tests for the probation office as well both within one day of each of the two “failed” tests. I guess what I’m getting at, is unfortunately we do have to sometimes worry about rare situations from human errors. I have a feeling your friend will be ok once the actual lab comes back with their results. (of course, the “clean urine” that she had been getting from somewhere could have forgotten about the medicine they were randomly prescribed for an oral surgery or something just as crazy!) curious the final outcome of your friends situation??

    Need advice!! Today I had pre-employment UA. I am not a regular user but i dabbled about a week ago. I have used synthetic urine before without problems so i just decided to take no chances and use it again to make sure it would all come back clean. Well fuck me, at this particular place of employment, they make you get completely (bra and undies too)undressed and put on a gown! I panicked! The nice person let me keep shoes on which was my saving grace as I slipped the sub into my shoe. I went in, provided the sample and gave it to her. She said the temp was out of range (low) and i would need to provide another sample within 2 hours after drinking water in their lobby. as i had time to sit and ponder (and google) i decided to just give my own urine and reap the consequences if it came back positive. This time they directly supervised me so I really had no choice anyway. Second sample was fine with temp and all negative. Whew! Should have just done that in the first place. But here’s my problem: They now have to send both negative samples to an off-site lab because “the first appeared to be adultered.” when they say “adultered” do they mean I put something in it or that it’s synthetic? Is this new lab going to be able to detect that the first was synthetic urine?? If it comes back as that, what do I say to them?? i honestly think the temp was fine. Maybe low like 90, but still fine. I followed all instructions and I even checked the urine that i left in the bottle after i left the place and it said 94. I’m so nervous. But main thing is that I need to know if the lab will come back saying the first was synthetic. Anyone know?? I’ve scoured the internet for updated forums and this is the most current one, so I hope there is someone out there right now that can offer up some advice. Thanks!!!!

  60. COtired

    I also wanted to add that my real sample looked a lot different from the sub sample. A lot darker. Will that be a problem, too?

  61. COtired

    Anyone have an ideas for me? I posted a couple days ago , no responses. I am so stressed!!

  62. Ron

    Sub Solution FAILED for me.

  63. Ron

    Just kidding. Wanted to make sure these comments were being published.

  64. Dave

    Hi all, I’ve been doing research on sub solution and have seen comments saying it wasn’t reliable as of September 2016. Has anyone used sub solution within the last month or so and passed? Responses would be much appreciated.

  65. Syd

    If anyone would be interested, I bought Quick Fix Plus and I don’t need it anymore. They don’t take returns and I paid $50 for it and I’m really trying to get rid of it. I would sell it for like $20. It’s completely unopened.

  66. Stunnah

    Just lab tested for a job within the last week using subsolution. Screen included specimen validity testing (SVT) and I passed. In addition, I read literally every thread about subsolution and it seemed like *nobody* used the heating powder…so I decided to take the chance and use it since there were no/few first-hand accounts. I admit, I was worried that it might throw off the pH (since most heat reactions of that nature create salts), but the shit is so damn expensive, I just had to take the chance and try it since I was paying for it. It was definitely easier and less stressful than experimenting with heat packs and whatnot. Temp seems to be the only thing to fret about, but you can experiment with the powder ahead of time and you’ll see how easy it is. It heats up very quickly and cools down at a manageable rate. Easy peasy. I was reallllly skeptical about using synth, but it was my only viable option. I’m quite impressed (perhaps a bit surprised) and it was well worth the money as you might imagine. The only problem I encountered was that the bottle they sent me leaked a bit even when fully tightened. Nbd though, the leak wasn’t appreciable enough to make a difference. I stressed hard about this whole ordeal, as anyone else in this situation likely will, but it worked out. Just stay cool and don’t trip…too much. I hope this helps. One love.

    I just wanted to post about my drug test. The absolute only choice in my area, or even close was QuickFix. Yellow box, 6.1 version. I prepared it as according to directions, went to take test, and it was postponed. I had to reheat it 3X before actually using it. Everything came back perfect. Awesome! Here’s a serious piece of advice, do not trust the heating pad it comes with! Get two hand warmers from the hunting section at a department store and use BOTH of them. The pad they offer isn’t going to hold temp if you don’t get right in…it may, but are you really willing to risk it. This is what I did, made sure they are fully heated before attaching them to the bottle (30-45min). It will hold the temp exact. So absolutely happy it all went well. Here’s to the new job!

    I need and overnight shipment please contact asap

    The Quickfix urine I tested where I worked and it showed positive for nitrates. I used it for a drug screen. What is going to happen? Will I be OK?

  71. MrMyddy

    It is 2/23/17 and I took urinalysis using Sub-Solution 2 weeks ago. I am a manager for an oil & gas company and still havent been fired or called about it so I’m pretty sure it worked. I submitted my sample to an occupational med clinic so it was shipped off to a lab (idk who). I was freaking out about the “6 hour shelf life” talk in the directions because it was a thursday afternoon and it probably wasn’t going to be tested until the next day or even possibly sit over the weekend. It is safe to say it has been tested by now and i have not heard anything about it so it worked. I did not use the heating powder as i warmed it up and kept it in my leg prior to testing. I have a good job and a good career and sub-solution kept it that way.

  72. Fish

    Can you mix a lil clean urine with fake to make sure you have enough to fill the cup?

  73. well then

    Yeah I guess I’m just gonna have to quit. Not risking my 75k/year job.. You shouldn’t either. The only sure fire ways to pass a drug test: Quit and detox naturally, or tape a bottle of your sober friends pee to your leg. That’s it.
