UPass Synthetic Urine Review

upassUPass or Up Ass?

Upass synthetic urine has an unusual name. It’s no where near as cool as Urine Luck, probably the best-named synthetic urine on the market. But at first glance U Pass Synthetic Urine as in You Pass Synthetic Urine is a pretty catchy name. But upon closer inspection the name reads more like a suppository than fake piss. Read the name again. It’s not U Pass it’s UP ASS. Get it?

UPass Synthetic Urine

Anyhow Upass synthetic urine is lesser know brand of fake urine. The online reviews of U Pass synthetic urine are hit and miss, much like Magnum Detox synthetic urine. The fact that it’s not well-known and has mixed reviews might give you pause when considering using it to help you pass your urine drug test for weed. But then again you might be in a head shop staring at a box of Upass with a drug test in your immediate future and wondering if it’ll work. If this scenario sounds familiar urine luck…we mean you’re in luck because we decided to test U Pass synthetic urine to see how well it works.

How to use u pass synthetic urine

Granted we don’t have some hella expensive piece of lab equipment, but we did use an over-the-counter marijuana test that’s tough to fool. How’d u pass do? We’ll get to that. But first a little about upass. According to Amazon, where we purchased a 3oz bottle of U Pass synthetic urine version 8.4, this stuff is called “Fetish Urine.” Why? Well like the legendary Whizzinator U Pass fake piss also needs to be referred to as a sex product rather than a product used to beat a drug test for it to be sold legally. The disclaimer on Amazon read: “WARNING: This product is not intended for unlawful use and is not intended for human consumption. Keep product away from children, kit contains small plastic parts, harmful if swallowed. Consumer agrees to all applicable Federal, State and Local Laws concerning the legal use of this product.” How silly, eh?

Despite not finding any specific u pass synthetic urine instructions in the box it did work quite well.

U pass performance

How did upass synthetic urine perform? Despite not finding any specific U Pass synthetic urine instructions in the box it did work quite well. It fooled our home marijuana test. So that’s something. And according to the interwebs Upass urine has also helped several people beat drug tests and or their drug screening. Just check out all the favorable reviews on Amazon.

Not only does U Pass synthetic urine work well to pass a drug test, it’s also pretty cheap. We scored our test sample of U Pass on Amazon for around 12 bucks and it came with free next day shipping. Unlike our recommended synthetic urine, Sub Solution, the Upass urine didn’t come with a warming powder. So you might want to get yourself hand warmers to heat the urine before you hand it over to the testers. If there’s one sure way to fail a drug test it’s to hand off cold piss. Pee comes out of your body warm. So make sure your sample is also warm and you’ll be fine.

    I used upass about a week ago for a temp service drug screen that was taken in office. I kept it warm in my undies near my hoohoo. I passed that screening. I used it again today at an actual lab (LabCorp). They send it off to another branch & I’m told the results will be back in 24-48 hours. I’ll keep you posted on the results.

  12. Lucky Dog

    Ok everyone sorry I took so long to respond I took u pass 8.4 urine for my drug test and she was stareing stareing at it for awhile and I started sweating bullets but I passed it and got my 60 subs that’s why I have to take a drug test anyways to get those suboxone strips

  13. Me

    So I just brought n have to take a drug test tomorrow. Is upass the real deal. I’m a heavy smoker and my job depends on it

  14. Lucky DOG, @ ME

    HEY ME Depends on if your job sends it to a Lab or if THEY just let you pee and then test it right on the spot if they do right there real fast just make sure you use the hand warms to get the temp to 98 I had no problem because the doctor has us just pee in a cup with our name on the cup and 15min later the nurse tests the pee and dont test the temptature they do a instant drug test and I used U Pass and I Passed so tell me if you know how they do it were you work

  15. Smoker

    Have to take a rapid drug test for a new job I was offered, saw this stuff in a local smoke shop and was told it works great and from the reviews it sounds like it works well. I’ve been a heavy smoker and I’m a big guy so even if I stopped smoking for a month I’d still be dirty for weed. Will this product work for a rapid drug test as long as it’s to the required temperature? I’ve been at a dead end job for 7 years and this is an opportunity to progress in life and better myself. Any input is greatly appreciated! Thanks guys.

But PLEASE dispose of it, I got pulled over with a little left in the bottle and it tested positive for methamphetamine on a field test. Pending lab results I’m looking at 10 years for trafficking because of this shit so beware

  34. Jerred hawkins

  35. Stressed out

    Hey look.. for those of you who are reading this I smoke 2-3 blunts everyday of some gas, loud, high grade whatever you want to call it lol I’ve been smoking everyday for 7 years . I just moved up here from Orlando FL to Atlanta GA, I applied at pilgrim poultry factory and their pay rate is $10 an hour I can make more after three weeks of training up to $12.75. Once I start I get payed every week… that’s over $300 every week… yeah I’ll be making some change . They told me I had to go to a drug screening and is really shitting bricks right now cause I need these job so bad. I bought u pass an honestly don’t even know if this shit works at all

  36. Stressed out

    I’m supposed to take a drug screening at US healthworks medical group clinic tomorrow and honestly I need to know if this really works. A buddy of mine used this before and recommended this to me but after reading so many god damn forums and reviews I’m having so much doubt about this synthetic piss… almost every website recommends quick fix but I heard of so many scams with that fake piss it just seem like people would lie about this to real hard working people just to make a buck which is VERY FUCKED UP!!!

  37. Bart

    I’m an everyday smoker and recently I was surprised to learn I had to leave work to take a random drug test so I called my local smoke shop and they had UPASS 8.4. I bought it in desperation and after I used the hand warmers to get the temperature right, I gave the sample. The next day I got word that I passed so it definitely works if you get the temperature right, that’s all you have to do and UPASS does the rest. Its even premixed and comes with two hand warmers and a rubber band to attach to the bottle which has a temperature strip already on it. Use with confidence, it literally saved my life!

  38. Stressed out

    Yoo thank you so much!!! This shit actually works ok not going to lie I had my doubts but I went to the US Healthworks and took a ten panel drug test and passsed yo! All I did was boil the fake pee then used the hot sack in the box attached it to the back with the back with the rubber band! Put it in my pocket and I was good it stayed at 96 F

  39. Kin

    Definitely I’ve used it many times in this work but I also use it about 5 times and failed

  40. JohnT

    Can UPASS be reused after it already been heated and opened?

  41. [email protected]

    Has anyone used upass for a probation drug test, if so what was the results

  42. Yeah

    Upass definitely worked for me. Used it for a drug screening and physical (didn’t want to give different samples). Heated it in microwave for 12 or so seconds then wrapped it in hand warmers. Before I went in I took off the hand warmers, waited for it to drop to 98 degrees, and stuck it my 2 pairs of briefs I had on (wedged between my balls and thigh). Wore kinda baggy pants. Oh and carefully press on the bottle–it made a whoosh noise as I must’ve pressed too hard, but wasn’t heard.

  43. John

    I used upass and waiting on results nervous 😣

  44. Sunnid

    Just used upass last week for a dt to get a job after being unemployed for 2 months….they r sending it to the lab and I’m on edge waiting for these results.

  45. Sunnid

    Upass does indeed work for a lab dt! I got the job and i start Monday! Having a celebration smoke! Just wanted to give hope to my fellow stoners!

  46. Jankum

  47. Blue
