This U Pass review was last updated in August 2019.

UPass Urine (also known as U Pass 8.4 or You Pass) is fake pee which is used in drug screenings or urinalysis. It gained a lot of good reputation a few years ago. However, in the world of drug screening, technology doesn't stand still.

Too many synthetic piss products that used to work perfectly fine, will now guarantee you a shitty result. And nothing messes up your career or job opportunity more than a failed piss test.

Facts:

  1. Urinalysis is one of the most reliable substance checking methods being able to detect more substance than any other method.
  2. Drugs stay longer in urine, for example it can take up to 60 days for marijuana to leave your system.
  3. Using synthetic products is by far the most popular solution helping users pass a screening.

In this article, we'll give a complete review of this product and discuss how effective it is in passing drug tests.

What Is U Pass Urine?

Upass urine is a synthetic urine sample that is used for the calibration of testing equipment.

Essentially, it is a baseline product that scientists use to rest their equipment and make sure that all tests are accurate. By using such a product, you will be submitting a sample that shouldn't be flagged as fake, thereby passing the test.

But does it actually do that?

How does it fare against drug screenings?

Health Box

If you take any kind of recreational drugs, legal or illegal, then they will be picked up in urine tests.

With so many employers these days demanding that employees and applicants get tested regularly, it’s no surprise that there is a huge market for fake pee.

UPass 8.4 did have quite a long run of being a great solution for passing urinalysis tests in most labs, but recent changes in testing machinery have changed its success rate a lot.

It’s still marketed and advertised a lot, but unless you know that a testing facility is not fully up-to-date with its testing, UPass 8.4 won’t be the best or most reliable solution. This is simply not a risk worth taking when your job and life is on the line.

What are the Ingredients of UPass?

When it comes to passing a urine test it’s all about getting the composition just right. This doesn't mean that you get a sample with all the common everyday toxins, glucose, ketones and even a bit of DNA mixed in.

And that’s OK, because drug testing doesn't test for these kind of things. What they check for is drugs and a few common ingredients of human organic pee.

So, how does Upass 8.4 hold up when it comes to ingredients?

Here’s what’s in it:

  • Proper creatinine levels
  • Specific gravity (more on this later)
  • pH balance
  • Urea
  • Color
  • Odor

At first glance that all looks fine, but there is a crucial piece missing, and that’s uric acid. The majority of testing facilities will do a simple test for uric acid, and if it’s not in the right concentration, then the test will immediately be marked as fake.

And that’s the major downside with this product.

Let's take a closer look at some of these ingredients.

Creatinine

Creatinine levels of the sample should not be below 15Mg/Kg of body weight, otherwise it will look diluted compared to human pee. Creatinine is a natural substance that is produced as damaged muscle tissue is replaced. The kidneys filter it and it’s sent out with your piss.

pH

UPass 8.4 has a pH of about 6 to 7. This is the pH of normal urine, and therefore any artificial product you consider buying has to have a similar level.

Urea

This is one of the most common substances tested for these days and is always present in urine. It baffles me how many people still buy fake pee that doesn’t have urea. It’s the most obvious sign that what you've submitted isn't the real deal.

Color

Normal human pee has a yellowish color and a strong odor. To avoid raising any suspicions during the test, U-Pass has the right color and smell.

What's in the UPass Package?

testing sample

UPass contains 3 oz. of the solution, a plastic bottle, heating pad or warmer, thermometer (used to measure the correct temperature), rubber band (used to strap the hand warmer to the UPass 8.4 bottle), and a set of instructions.

Passing A Test With UPass (Instructions)

  1. FailOpen the product, heat the fake piss in a microwave for 10 seconds. You want the temperature to be between 94 -100 degrees Fahrenheit when submitting your sample.
  2. Close the Upass 8.4 bottle and shake well ensuring that the liquid has been mixed properly. If the bottle feels too warm to touch then give it time to cool down to the optimal temperature.
  3. Using the rubber band, strap the hand warmer to your UPass bottle. This hand warmer will supply the device with a heat source to keep it between 94-100 degrees Fahrenheit.
  4. Before you head into the testing facility, make sure that the sample is between 94-100 degrees Fahrenheit and put it into the collection cup. Put in a little less than what is in the bottle so that your piss sample is not exactly 3 ounces. This will ensure that the person-in-charge of the screening does not suspect that a pre-measured amount is being submitted.

The product does come with instructions inside, so please read every step carefully. Always keep in mind, you will be nervous. Practice this as many times as you can as when match day comes you won't get a second chance.

Does Upass Urine Expire?

Yes, Upass does expire, and you shouldn't trust its usefulness beyond 1 year.

The reason is that it will gradually deteriorate giving you a sample that doesn't have the right concentration.

You should also never submit a sample that you have mixed more than a few days earlier. This is because the water will evaporate and that will increase the concentration of urea.

Such simple mistakes are usually what causes people to fail these tests, rather than the product being unreliable. Always follow the instructions and don’t take any chances.

Our Honest Review of U Pass

How Much Does It Cost? - Good

It is cheap to buy at only $18.99. You can't complain about their sale price, but it's not always about the price when it comes to these things.

Also, these prices can vary if you buy them from Amazon, eBay, or Craigslist if you do find them on there.

Be very careful to check the dates for any positive reviews that you find. This was a popular and reliable product until testing started to focus on uric acid as well.

If you see it for sale with a load of positive feedback, then the chances are that those reviews are more than 3 or 4 years old.

These days, it isn’t a very reliable product anymore.

Adulteration - Good

contaminated sign

The product for sale must be checked for adulteration before buying. This is highly important if you want to pass.

Adulteration means the sample has been contaminated, diluted, and tampered with.

According to research done on the use of UPass 8.4, it was indeed confirmed that this product is free of adulteration and therefore is a safe product.

Success Rate - Poor

Reports have shown that UPass 8.4 has had mixed results with many users complaining they failed the test. However, a larger percentage of marijuana users around the world gave positive comments and success stories after using the product in their drug tests.

About 80% of the people who have used the U-Pass 8.4 during their tests, posted a positive result/pass online. Keep in mind that those results are a bit older and in recent years the success rate has dropped a lot.

This may be enough guarantee for you, but it certainly isn't enough for me.

My alternative (see below) has less than a 0.02% fail rate.

Frequently Asked Questions

What temperature should U Pass be so that it can perform well?

U Pass should be 94 to 100 degrees Fahrenheit so that it can perform well and increase your chances of passing the test. The reason for this range is this is the expected body temperature according to the testing facilities. 

Can you heat U Pass again?

Yes, you can heat U Pass again, but make sure you avoid doing this too often. After a couple of times of going through this process, water will evaporate and it increases the concentration of the sample. That can then be picked up as an unnatural and fake sample.

Does U Pass's box accommodate a temperature strip?

Yes, the U Pass box accommodates a temperature strip which is a vital part of the preparation process. Once you get the sample up to the ideal temperature, you will need to keep it close to your body to avoid cooling. Before you head into the test facility, double-check the strip to make sure it’s still at the right temp.

Will U Pass decay?

Yes, U Pass will decay over time, but the shelf life is pretty long. When you mix it and heat it at least once, it’s best to use it within a month as some of the water will evaporate and the chemicals can start to break down as well.

Can U Pass be frozen?

Yes, U Pass can be frozen and used at a later date. However, you should avoid going through this process more than once. Freezing and defrosting will slightly change the chemicals, and the more you do this, it will impact the sample more negatively.

Can U Pass be purchased in stores?

No, U Pass is not available in stores, and I would caution you about buying it from any non-reputable company. It is available on Amazon from time to time, but the best place to get it is directly from the manufacturer.

Does U Pass smell unpleasant?

Yes, U Pass does smell unpleasant, but no different to regular human piss. It’s the mixture of chemicals that gives pee the very recognizable smell, and if it didn’t smell bad, then it would easily indicate that it’s a fake sample.
