Urine drug tests are the bane of many people’s existence, and folks go to extraordinary measures to ensure they pass. This includes using bags of fake urine (like UPass Synthetic Urine), which some people think actually work to help pass a drug test.

Here’s the thing.

Urine tests have gotten so advanced, most employers can now detect kidney metabolites which simply can’t be replicated in fake urine. So if you use a product like UPass Synthetic Urine to try and pass a drug test, the test will more than likely come back void – at which point you’ll have to take it again.

FORGET the FAKE URINE! It Doesn’t Work…

Fake urine products are basically elaborate scams – if you think they actually work to help you pass a drug test, well… you’re in for a rude awakening. The good news is there are companies that make advanced dietary fiber detox treatments that actually do work to quickly detox the body of THC metabolites. If you’re stressing on an upcoming drug test and need to detox your system fast, this 24-hour urine detox treatment was by far the best when we tested out a few products earlier this year:

Fake Pee Products: Interesting, But They DON’T WORK for Drug Tests!

A lot of employers even count a void test as a failed test. Neverthless, when they find themselves in a pinch with no time to detox, a lot of people still wind up ordering products like UPass fake urine in the hopes it will be their golden ticket to a passed drug test.

Our team actually ordered UPass synthetic urine and tested it with three popular at-home drug testing kits.

The results? Each test came back void.

We tested UPass synthetic urine with three popular at-home drug testing kits, and each one came back void.

The good news is we’ve tested other products that actually work really well at helping rid urine of THC metabolites – some of which even worked within 24 hours of a drug test. Our favorite was a dietary fiber detox from ToxinRid which produced nearly instant results, even after using it consecutively with three different at-home drug test kits.

In this article, we discuss in detail our findings after completing a UPass Synthetic Urine review, and why we believe other products provide far better solutions when it comes to quickly detoxing prior to a drug test.

Upass Synthetic Urine Review: How Does it Work?

UPass aims to replicate real human urine by mimicking specific levels of creatinine, pH, color, and temperature. The problem is, hundreds of other compounds exist in urine, and drug tests have advanced to the point where fake urine kits, like UPass, are more or less obsolete.

Furthermore, it says right on the packaging of the UPass fake urine kits that the product is for ‘research and novelty use only.’ They never claim it works as a substitute for actual urine during a drug test.

If a person wants to scam drug testers by using urine other than their own, they’re better off collecting urine from another person and using that for the test instead of a product like UPass. (Not that we’d ever recommend doing that, as it’s clearly against the law).

Simply put, products like UPass Synthetic Urine kits simply don’t work when it comes to helping people pass drug tests. At least not in our opinion.

So What Should You Use Instead?

If you’re trying to detox your body as quickly as possible before a drug test, you’ll have far better luck using an advanced detox kit that soaks up metabolites via dietary fiber.

The best detox kits we’ve used start working within one hour, and in most instances they can fully detox the body from THC within 24-hours. They’re also 100% natural and contain no artificial fillers or synthetics. Simply put, they’re a way better option than something like UPass fake urine.

Unlike fake urine, professional 24-hour detox treatments start working within one hour, and can fully detox the body in a single day.

Our Personal Experience with the UPass Testing Kit

After trying UPass out ourselves, we found it to be a straightforward and simple kit. We ordered from the official site, and the kit arrived within four business days under standard shipping. The UPass kit itself was nicely packaged and had all the items stated on the website.

Make no mistake – UPass synthetic urine looks exactly like real pee! It smells like pee, and has the same consistency, too. This was a definite plus to actually see this in person. Every review we had read was accurate, and it checked out to be exactly as we were expecting.

When using the kit, we followed all the steps to a tee. First we put the UPass urine in the microwave, then shook it up. Everything in the bottle fully dissolved and was homogenous. After strapping the heat warmer, we tested to see how long it stayed warm, and it was a little under two hours. In all fairness to the company, it was pretty cold in the room where we did the test, so this may have had an effect on the lasting of the heat pad. (In any case, you can always buy more hand warmers to maintain a consistent temperature).

After heating, we squeezed the bottle into a little cup to make sure it would foam up and look like real pee, and it was. It honestly was as if we had just urinated into a cup. As we’ve mentioned above, the problem with fake urine kits like this is they don’t register on actual drug tests. Every single at-home drug testing kit we tried, in fact, produced a ‘void’ result. This is likely due to dozens of metabolites that are present in natural urine, that simply can’t be replicated in fake pee.

What is the UPass Synthetic Urine Test?

The UPass synthetic urine test is a product that’s manufactured to mimic real human pee. It says on the box that it’s only intended use is for research and novelty purposes. Contrary to popular believe, UPass is not a product that’s designed to help people pass a drug screening.

Still, people use it for work, sport, and other occasions where drug testing is mandated. UPass is regarded by many as the best kit on the market, and it’s true that the people behind the brand have put a lot of time and effort into mimicking the critical components of human urine.

The bottom line however is that this is not a product that’s made to help people pass a drug test.

Key Ingredients

The first and primary ‘ingredient’ in human pee is urea, also known as carbamide. Urea is the substance that gives pee its smell and color. A test without urea in it would be instantly identified as fake. UPass Synthetic Pee does in fact contain detectable amounts of urea.

Another key ingredient in the UPass formula is creatinine. Creatinine is a chemical waste product produced by the body’s muscles, and excreted through the kidneys. Without normal creatinine levels, a person’s urine sample is also sure to be seen as a fake by the drug tester.

UPass fake urine kits do a good job of mimicking urea, creatinine, and pH levels. The pH content of urine can range anywhere from 4.8 to 8, and UPass has done an incredible job of making sure its products meet these wide ranging criteria.

There are other parameters (i.e. replicating temperature, foam, and specific gravity) that need to be executed by the user in order to mimic the exact conditions of a natural urine sample. For example the kit comes with a hand-warmer that is used to heat the sample to a realistic temperature of 98˚F (37˚C), which is the usual temperature for pee. The kit even comes with a squeeze bottle to recreate urine stream pressure in order to generate foam.

Without a doubt, a lot of thought has been put into the UPass product line. As long as you follow the kit’s instructions carefully, the UPass urine kit will almost certainly make it seem like you’re dealing with real, authentic pee.

How to Use the UPass Synthetic Urine Kit


The first step is to use a microwave to heat the bottle of urine included in the kit. The internal temperature of urine is anywhere from 94-100˚F (34-38˚C). Depending on your microwave and its wattage, the time to reach this temperature varies, but it’s usually around 10 to 15 seconds. Do this at home, then use the hand warmer to maintain the temperature (it lasts about 2 hours). If you need to maintain the temperature for longer, you can purchase additional hand warmers to extend the time.


With the bottle of urine from the UPass drug testing kit heated to the precise temperature, you’ll then need to shake the bottle until its contents are thoroughly dissolved. There should be nothing grainy remaining.


Secure the heating pad to the bottle of UPass fake urine. This is easily done with a rubber band that’s included in the kit.


The amount of UPass fake urine in the synthetic drug testing kit contains exactly three ounces of fake pee. Most users pour a little out so it’s not a perfect three-ounce sample (which may raise suspicions).

Additional Information on UPass Synthetic Urine Kits

In short, UPass drug testing kits have become a popular choice among people looking to pass a drug screening. Of course, the kit only works for urinalysis and not for other methods like hair or saliva screenings. However, since urine tests are the most commonly used screening method, products like UPass are very widely used.

UPass urine goes through rigorous inspections to make sure each sample is accurate. This is of course crucially important if you plan on using fake pee for a drug test.

All in all, the rigorous science and testing that goes into the kit does a good job of replicating conditions of pH, creatinine, foam, heat, specific gravity, and other internal urine contents. The kits are also simple to use, and many regard their quality as the best on the market.

For those looking for a reliable synthetic urine testing kit, UPass is a good option. As we’ve said several times however, all of the drug testing kits we tried them with produced a void test result.

Fake Pee: Big Business, Bigger Failure

Believe it or not, these types of urine kits are big business. There are an assortment of different brands and products to choose from, but Upass is an old hand in the industry, and its product line is easily one of the most reputable on the market.

Unfortunately, it’s not the early 2000’s anymore, and drug testing technology has far surpassed the technology that even the best fake pee products (like UPass) are using.

We also highlight the fact that this article is not intended to advocate for the use of a synthetic urine test. Our simple goal is to inform readers on how to use them safely, so they can have a successful and smooth experience when the time comes to pass their test.

How Much do UPass Synthetic Urine Kits Cost?

We’ve covered most of the basics of the UPass synthetic urine kit, but depending on your budget and what exactly you’re looking for, the company does offer other Upass urine products. The synthetic urine inside each UPass kit is more or less the same, but some kits contain supplementary components, like biocide, which work to inhibit unwanted bacteria that may show up on a screening.

To find the right UPass urine kit for your needs, you’ll want to go to the company’s official website and browse the complete product line.

You’ll also want to be sure to read plenty of reviews. UPass synthetic urine reviews have given us insight into the many people who have used this product, and by most accounts, people enjoy the product’s simplicity and ease of use.

Currently, UPass Fake Pee kits cost $29.95. This is for a single-use kit that supplies 3 oz of fake urine. As you can see, the UPass kit has many pros. It is easy to use, comes with simple-to-follow instructions, and is tested to ensure a chemical composition. There should be no problem using the kit; just make sure you practice in advance and are well prepared.

The All New UPass Synthetic Urine 8.4 Kit

The UPass label has been around for years, and the UPass synthetic urine product line has undergone several variations over the years. The current version of the kit is the “UPass 8.4,” though this is likely to be updated again in the future.


Included in the UPass 8.4 kit is everything you need for a successful fake urine test. You’ll get:

  • Three ounces of UPass synthetic urine
  • A special bottle to store the urine in that helps in retaining all the heat from the microwave
  • A heating pad
  • A rubber band to secure the heating pad to the special heat-retaining bottle
  • Complete step-by-step instructions on how to use Upass 8.4

The UPass product is currently on sale for $29.95 (it’s usually $39.95) from the company’s official website. Before you think about buying, though, be sure to read other UPass product reviews from people that have actually bought (and used) the product themselves. This will provide you with an additional range of insight so that, when the time comes to use the kit, you’ll be more than ready.

Where to Buy UPass 8.4 Online

You can easily buy UPass synthetic urine and find it for sale in a few different online stores. The most popular sites that offer UPass 8.4 for sale online all offer free shipping, but no returns or guarantees. Basically, if you use the fake pee, it’s yours and there’s no going back.

The best way to buy UPass synthetic urine, however, is from the company’s official site. Of course, if you find UPass coupon codes or discounts, you could just as well buy it from other sites.

All in all, it’s pretty much up to you where you feel is best to purchase it, based on price, but if you’re wanting to order a synthetic drug testing kit online, these two sites seem to be the most reputable.

Unfortunately, UPass cannot be bought in stores, at least not to our knowledge. If you are planning on using cannabis and currently have a job that may drug test you, it may be best to stock up on synthetic urine kits beforehand. This will ensure you are always prepared.

It is also worth pointing out that neither of these above-mentioned sites ship to P.O. boxes – you’ll need to give a home address. Some sites offer a deal to buy 3, get the 4th free – this is an excellent way to save money, and have plenty of kits at your disposal.

UPass products ship from Cincinnati, OH, and have an option for 2-day express shipping. They also have a plethora of other products, such as a leg strap for an even more realistic approach to help you pass a test. You never know the circumstances under which the test may be administered, so it’s always best to be prepared.

Final Verdict About the UPass Synthetic Urine Kit

All in all, the Upass synthetic urine test is a popular way to use fake pee during a drug screening. The only problem, in our experience, is that it doesn’t work.

UPass Synthetic Urine Review: 2.5/10

Fake pee products like these may have worked in the past to help cheat drug tests, but the reality is rug screenings have gotten way more advanced. For example most now can identify miniscule kidney metabolites, which aren’t present in products like UPass Fake Urine. If you use UPass Synthetic Urine to try and pass a marijuana drug screening, your test will probably come back void, meaning you’ll have to take it again.

FORGET the FAKE URINE! It Doesn’t Work…

Fake urine products are basically elaborate scams – if you think they actually work to help you pass a drug test, well… you’re in for a rude awakening. The good news is there are companies that make advanced dietary fiber detox treatments that actually do work to quickly detox the body of THC metabolites. If you’re stressing on an upcoming drug test and need to detox your system fast, this 24-hour urine detox treatment was by far the best when we tested out a few products earlier this year:
