How does it all work though?

Well, a lot of research and science is where it all started. The creators of UPass spent a lot of work replicating the internal and exterior characteristics of human urine.

UPass synthetic urine functions by simulating actual human urine – from the color down to the temperature.

Scientists have created a synthetic formula that is remarkably identical to the actual thing by meticulously studying the chemical conditions and characteristics of human urine.  Many well-known brands create their fake pee kits to closely resemble natural urine in both composition and appearance.

By most accounts, the urine kit duplicates the precise conditions of pH, creatinine, and even color, and they function with almost 100% accuracy.

The technical aspects of synthetic urine tests are a little complicated; however, the kit’s instructions are simple and make it easy for most people to submit a successful false urine test.

One UPass synthetic urine package contains:

  • Thermometer strip
  • One plastic bottle – to reduce heat loss
  • Three ounces of synthetic urine
  • Rubber band – to attach the heating pad to the plastic bottle
  • Heating pad – to get the perfect temperature
  • Hand warmers
  • Instructions

These kits, believe it or not, are very popular. There are numerous products and brands available, but UPass has been around for a very long time, and its product line is unquestionably one of the most trustworthy on the market.

Who Should Take UPass Synthetic Urine?

In recent years, drug testing has become mandatory when it comes to employees and job applicants.

Additionally, these screening tests are performed on a regular basis. This is one of the main reasons why synthetic urine has a sizable market and why it is suitable for those with or looking for a job.

If you’re a recreational drug user and have a drug screening test coming up, you should certainly consider purchasing a UPass synthetic urine test. Recreational drugs include marijuana, which is also known as weed, pot, or cannabis.

Of course, the kit is ineffective for other drug testing procedures such as hair or saliva tests. It solely functions to get past a urine drug test.

Products such as the UPass kit are far more widespread than you might imagine because urine drug testing is the most popular screening method among employers.

UPass urine is rigorously examined to ensure that each sample is accurate. Of course, this is of utmost importance when utilizing fake pee as a drug test.

This means that you can live your life as normal, even if you have a vital drug screening test coming up for your current or potential job.

To use UPass effectively, you must first understand how this solution is put together. The composition and temperature are crucial factors in passing a drug test.

Urine includes common toxins that drug tests can’t identify. They only test for various drugs and some of the usual components found in human urine.

You can find the following ingredients in UPass synthetic urine tests:


Urea is also known as carbamide. It is the substance that gives urine its color and smell and is probably the most common ingredient tested for in urine tests. It is also the most popular way to tell if your pee is real or fake.

The concentration should range between 12 and 20 grams. A synthetic urine solution is a waste of money if it doesn’t have urea.


The kidneys remove creatinine, a chemical waste product created by your body’s muscles. If a urine test doesn’t have normal creatinine levels it will automatically be detected as fake.

When it comes to creatinine, there is a certain quantity or concentration benchmark that needs to be met.

There shouldn’t be less than 15 milligrams of this component per kg (2.2 pounds) of your body weight in pee or a vial. Anything less than this will make the solution seem diluted.

Furthermore, your body naturally produces creatine when your injured muscle tissues are restored. When you urinate, your kidneys remove this material from your body. As a result, its concentration ought to range between 631-2,936 mg.

pH Balance and Specific Gravity

The pH range of UPass is six to seven, which is the same as the pH of the original urine. Any additional synthetic urine product needs to fall inside this pH range. According to reports, UPass synthetic urine has a specific gravity that is similar to that of human pee.


Original pee typically has a strong stench and is amber or golden in color. Additionally, a synthetic urine solution needs to be the proper shade and scent.

Other Factors

The user must replicate temperature and foam in addition to other characteristics in order to accurately reproduce the conditions of an actual urine sample.

The sample is heated in the kit using a hand-warmer to a practical temperature of 98 degrees Fahrenheit, which is the typical temperature of urine. A squeeze bottle is also included in the package to simulate the stream pressure that produces foam.

Simply said, the UPass product range has been well thought out. In essence, the synthetic pee deceives the drug testers or lab into believing the sample is real.

Any Downsides

The potential drawbacks of UPass synthetic urine include:

  • UPass is illegal in certain areas: It’s critical to conduct research on the rules or legislation governing drug testing in your state, province, or region. UPass might be illegal in your area, and if they discover use, it might result in legal repercussions.
  • It’s not suitable for carefully supervised drug tests: It’s highly possible that you won’t pass a drug test if it’s being closely observed, particularly if you’re not given any privacy.
  • There are a few negative claims: UPass urine, according to some users, does not assist in passing drug tests. It hasn’t been established if these users correctly followed the directions or whether there were other elements at play, so it remains a claim.
  • If detected, you can get in serious trouble: If you try to dodge a urine drug test and are caught, you could face substantial repercussions if you work for the government or for a corporation that has ties to the government.
  • UPass packages exclude a Whizzinator or fake penis: The UPass urine package does not contain useful items such as a fake penis or Whizzinator, unlike other competitors. Therefore, you will need to purchase them separately, which means additional expenses.

Results from Users

There are numerous positive and negative reviews for UPass synthetic urine, which means that everyone has a different outcome depending on their circumstances. Overall, the response to UPass has been quite positive.

Numerous instances may attest to its usefulness. From Amazon reviews to Reddit reviews, you can find hundreds of positive online reviews.

Users who regularly consume cannabis or marijuana said that UPass helped them pass a urine drug test.

However, for those who used other recreational drugs, the results were different. This does not prove categorically that UPass is not always successful at passing particular drug tests; for instance, urine is typically used in lab testing to look for THC or marijuana.

Overall, customer feedback suggests that UPass can be trusted, but only to a certain level. There are various reports that the success rate of UPass has substantially decreased due to technological advancements in urine testing apparatus.

However, the users’ partial compliance with UPass’s instructions is another factor to consider.

How to Use UPass

Step One

First things first, you need to heat the kit’s bottle of urine in the microwave. Urine’s internal temperature ranges from 94 to 100 degrees Fahrenheit. The time it takes to achieve this temperature varies based on your microwave and its wattage; however, it often takes 10 to 15 seconds.

Do this at home and then keep the sample at the same temperature using the hand warmer, which lasts approximately two hours.

You can buy more hand warmers if you need to keep the temperature up for a longer period of time.

Step Two

You’ll then need to shake the warm urine container from the UPass drug test kit until all of the contents have been completely dissolved. There shouldn’t be any graininess left.

Step Three

Attach the heating pad to the bottle of synthetic urine from UPass. Using the rubber band from the kit makes this task simple.

Step Four

The synthetic drug test kit includes precisely three ounces of UPass fake urine. It’s not a perfectly accurate three-ounce sample because most users spill some out.

In terms of price, it’s really up to you where to get it; however, if you’re looking to order a synthetic drug test kit online, these two websites appear to be the most reliable.

Fortunately, certain stores and gas stations also sell UPass. It might be smart to stock up on synthetic urine kits in advance if you intend to use cannabis and currently have a job that may subject you to drug tests.

By doing this, you can be sure that you’re always ready to feign a positive drug test whenever necessary.

It is crucial to note that the aforementioned website doesn’t ship to PO boxes; instead, you must provide a residential address.

Here’s a quick summary of the pros and cons of UPass synthetic urine:


  • It is affordable
  • UPass is a very popular synthetic urine package
  • You are likely to pass drug tests
  • It has a long shelf life
  • UPass synthetic urine is almost identical to human pee in composition


  • UPass is declared illegal in certain areas
  • There are mixed reviews
  • Not likely to pass carefully supervised drug tests
  • It does not include any additional products such as a Whizzinator
  • If detected, you can get in serious trouble


Does UPass Synthetic Urine Expire?

Yes, UPass does have an expiration date. Its quality would have declined after the recommended shelf period of one year, despite the producers’ claims that it can last for up to two years.

Is UPass Detectable?

Depending on the test, UPass is effective for basic drug tests such as those for THC or marijuana. Verify that the drug test you have been asked to take will be a urine test.

UPass cannot possibly be used for a hair follicle test or saliva test (mouth swab). You won’t succeed. Rather, try weed detox pills or mouthwash.

How Often Can You Reheat UPass Urine?

Before your urine drug test is scheduled, you can reheat your UPass pee as often as necessary to keep it within the ideal temperature range. However, after you’ve opened the urine bag, be sure to use it within eight hours.

Is UPass Synthetic Urine Legal?

Depending on the state, it may be legal or illegal. Therefore, everything relies on the state in which you live. The use of fake urine products has been outlawed in states such as Ohio and Texas.

Even in these states, it’s doubtful that you’ll face charges for having synthetic urine. Particularly for UPass, whose product plainly claims, “Exploration and Novelty Use as it were,” the legal situation is unclear.

Can You Use UPass to Influence a Supervised Drug Test?

You will have to be more persuasive if the lab technician is watching you. Furthermore, you’ll also need a Whizzinator, a belt, and possibly a fake penis. Your UPass urine bag can be fastened in such a way that it appears to be emerging from your “genitals.”

If you’re slightly confused, you can look up instructional videos that show you how to fasten a synthetic urine bag to your body.

Is UPass Close to Real Human Pee?

It’s quite close, but uric acid is one essential component that’s missing. Nevertheless, the remaining elements, including urea, creatinine, odor, pH balance, color, and specific gravity are present.

As a result, it has the same appearance as actual pee and the same odor. It looks the same from a physical standpoint.

Where Can I Buy UPass Near Me?

UPass is available in numerous locations. It is offered online at retailers such as Amazon, GNC, Walgreens, and the company’s official website.

Gas stations and traditional retail establishments such as Walmart also sell it.

Based on where you buy it, the prices change. However, we advise purchasing it straight from the manufacturer for quality assurance.


If you’re a little tentative in using synthetic urine, read the positive reviews about the U-Pass 8.4 online. Many people have used this synthetic urine to pass the drug test. However, not all of them pass the test.

For better results, we recommend the Powdered Human Urine Kit from Test Clear. This product uses real human urine not synthetic.
