A Review of UPass Synthetic Urine: Does it Work in 2023?

Last Updated on

The world is full of drug lovers! It’s just a part of the human condition, certain people love to switch things up every now and then; think different, feel different, and relax. I would know—I’m one of those people. But I also know that the law isn’t going to be kind to drug users. So as a functional addict, I needed a way to make sure that I could pass any drug test thrown my way.

One of the best ways to pass that kind of test is by using fake pee. You don’t want your entire life and career to be turned upside down by a few good parties, right? And freaking out about a surprise urine test isn’t exactly the best response.

In this article, we’re going to be looking UPass 8.4. We’re going to find out how it stacks up against other synthetic urines and if it can really help you pass your drug test.

What You Should Know about UPass Urine

First off: you should know that UPass 8.4 isn’t just used to pass urine tests. In fact, that isn’t even its primary purpose. There are a couple of other uses that people have found for it, including but not limited to:

  • upass fake pee packageFetish play: It’s marketed as “Fetish Urine”, after all. But as you’ll find out later, that’s exactly why this is a good way to beat a drug test.
  • Laboratory testing: Nothing like a bottle of fake pee to test stuff like diapers and toilets, right?
  • Animal repellent: Assert your dominance over your own backyard by beating your pets (or wild animals) at their own game.
  • Pranks: Finally, if you want a prank to remember, few things reach on the level of dumping fake urine. You may lose a friend, but you’ve been warned.

UPass Alternative
Sub Solution
Sub Solution is the best and most reliable UPass synthetic urine alternative on the market with over 99.99% success rate. It accurately replicates normal urine and comes with their patented heat activator formula.

Synthetic urine isn’t a new thing. Since drug tests have become more sophisticated—and more widespread—over time, people needed to find ways to balance their drug habits with their careers and lifestyles. A few puffs of weed never hurt anyone, but since the law doesn’t see it that way, the business of fake pee was born.

So What’s in UPass 8.4 That Makes It So Special?

Urea, uric acid, and creatinine are all natural compounds that can be found in our pee. UPass 8.4 has all these things, allowing it to pass for the real thing when it’s tested.

How? Well, you have to remember that this stuff was originally designed to be fetish urine. Some folks are into this kind of stuff, but using actual urine (with all the toxins and waste) isn’t exactly a healthy thing and REALLY kills the mood. That’s why they came up with UPass Synthetic urine, so people can get down and dirty without any potential health issues.

So they made a formulation that’s as close to actual human pee without actually being human pee. And it didn’t take long for people to realize that this had more uses than just the bedroom, and started using it to fool urine tests.


Where Can I Get UPass 8.4?

Since the niche of this product’s a bit wider than just people looking to pass their drug tests, it’s easier to find than other brands. There are some online platforms that carry this and are authorized resellers, so you know you’re getting the real thing.

Alternatively, you can always look up for the official dealer online, or walk to your nearest sex shop and hope that you’ll find a box there. You’ll have to spend a little bit for it, but if you really need to pass that test, what’re a few bucks to get you out of trouble?

How Do I Use It?

So you’ve gotten the notice for the drug test and have promptly purchased a box of UPass. What do you do with it now? Fortunately, the formula is ready to use straight out of the box, and you only need to tinker with it a little bit before passing it off to your examiner.

First, you need to microwave the liquid itself. This is really important since cold pee is a dead give away for fake urine. Fresh urine samples are often around 90 to 100 degrees Fahrenheit. Handing over a room temperature or cold sample is sure to raise red flags, so don’t skip this step!

The second thing you need to do is to mix thoroughly. Some compounds in the formula can settle or clump together while heating, so make sure that everything is dissolved! Check the temperature strip on the side if it’s showing the right numbers. If it’s too hot, let it cool a bit before going to step three.

Next, you’re going to want to keep that sample warm. Ideally, you should heat it up around five hours before your turn to take the test, as the handwarmer can only keep the temperature that long. Putting it in your clothing is good, but right next to your skin is better.

Finally, just make sure that when your turn does come around, the sample is still in the correct temperature range. Make sure to put an uneven amount so you don’t raise any question. Dump the solution in the cup, cap it, and hand it off. It’s that easy!

FAQs About UPass Synthetic Urine

Does this discriminate against male or female samples?

Not at all! Urine is universal, and so is this formula. It doesn’t matter what kind of lifestyle you lead, UPass can be used by anyone.

How long is the solution good for passing a test?

Not long. It’s best to schedule your order and delivery to a few days before your test actually happens. Any longer or earlier than that could be too late and diminish the effectiveness of the solution. Remember: timing is crucial when it comes to this kind of mixture.

Are there other things I can do to beat the test?

Definitely! You can try a cleanse, a detox formula, or drink as plenty of water as possible to flush the drug from your system. But be warned: these methods take time, and you may not have a lot of that once you get that testing notice.

Can I put other stuff in the UPass solution?

No. One of the biggest trip-ups of passing synthetic urine is if another contaminant is detected in the solution. Your fake urine solution already contains everything it needs. Just mix, heat, and pass.

Can I refrigerate UPass to make it last longer?

Never refrigerate! Remember, there are so many ways these delicate ingredients can be affected by things like temperature or other compounds in the fridge. If your test had been delayed past the best-by of UPass, bite the bullet and order a fresh box.


We’ve tried quite a number of products ourselves and all we can say is that Quick Fix 6.2 (learn more about quick fix plus) is the most popular product with the highest reported pass results. The good thing is you can get it directly from an authorized online dealer at a discounted rate.

Final Words on UPass

I personally found UPass 8.2 to be effective when I tested it myself. But others haven’t been so lucky…

It’s important to remember that despite its branding at its heart UPass is mainly a fetish product. It’s not meant to be subject to extreme levels of testing. So while it certainly helped me, reviews online have been mixed, especially when the user was subject to a more modern testing facility.

With this in mind, I can’t recommend UPass in good conscience. If you want to be absolutely sure that you’re going to pass your urine drug test, you should look into Quick Fix 6.2, which is thoroughly laboratory tested and has almost universally positive reviews.

So the next time that you find yourself in a bind because of a surprise drug test, take a moment to collect yourself and know that you have options. In this case, a buying synthetic urine that’s crafted to pass as the real thing. It’s easy to use and can be ordered in a snap of the fingers—so spend less time being wound up and more time enjoying the finer things in life.
