Upass Synthetic Urine: A Comprehensive Review and Guide

u pass synthetic urine

Synthetic urine has become a popular way for people to try and pass drug tests. With stringent drug testing policies in workplaces and legal probation requirements, many are turning to synthetic urine as a solution. However, not all synthetic urine products are created equal.

In this comprehensive guide, we’ll take an in-depth look at Upass synthetic urine, including reviewing lab test results, proper usage directions, where to buy, and better alternative products.

What is Synthetic Urine?

Before diving into the specifics of Upass, let’s review what exactly synthetic urine is.

Synthetic urine is a premixed laboratory-created substance designed to mimic the composition, look, and chemical properties of real human urine. Authentic human urine contains a specific blend of natural compounds like uric acid, urea, and creatinine, as well as electrolytes and minerals like phosphates and sulfates. The pH, specific gravity, color, foaming, and other characteristics are all carefully formulated to match real urine.

Synthetic urine is used for a variety of applications, including:

  • Passing drug tests – The most common use of synthetic urine is to provide a substitute urine sample during employment, probation, or other drug screening that tests for drug use. Since synthetic urine is drug-free, it can help the testee pass the screening.
  • Research – Scientists use synthetic urine to study urine, test medical devices, validate urine testing procedures, and in other applications where real urine would be impractical or unethical to use.
  • Prank props – Synthetic urine is sometimes used as a practical joke item or by Hollywood for comedic scenes involving fake pee.
  • Fetishes – A small niche fetish market exists for those attracted to urine for sexual or other reasons. Synthetic urine provides a clean and ethical alternative.

The synthetic urine market has exploded in recent years as more stringent drug tests have been adopted. Companies have raced to create synthetic urine kits that can pass the increasingly advanced urine test methods. This brings us to Upass.

Overview of Upass Synthetic Urine

Upass is one of the more well-known brands of premixed synthetic urine available today. It was formulated to mimic the natural chemical composition and appearance of real human urine to try and beat urine drug tests required for employment, probation, custody cases, and other situations.

Some key facts about Upass:

  • Produced by a company called Vale
  • Comes pre-mixed and ready to use
  • Claims to contain uric acid, urea, and other natural urine compounds
  • Available in 3-ounce and 8-ounce packages
  • Offered in Unisex version and also Female specific formulation
  • Uses food coloring to match expected urine coloration
  • Produced in FDA-registered lab according to company

Upass has been around for over 10 years and has gained popularity among those seeking to pass supervised urine screens. But does Upass synthetic urine really work as well as the manufacturer claims? Let’s take a deeper look at the details.

Upass Synthetic Urine Version History

Upass has gone through a few different formula revisions over the years. These include:

Version Year Notes
Upass 1.0 2009 Original Upass formula
Upass 3.0 2012 Improved formula version
Upass 5.0 2014 Tweaked with new compounds
Upass 7.0 2016 Further improvements
Upass 8.3 2019 Current version


The newest formula is Upass 8.3, launched in 2019. This is reportedly enhanced to better match the urine profiles that labs test for.

According to Upass, version 8.3 has the following properties:

  • Balanced specific gravity between 1.002 – 1.035
  • Creatinine levels of 15 – 300 mg/dL
  • Contains uric acid and urea
  • pH adjusted to match human urine
  • Valid shelf life of up to 2 years when stored properly

Upass 8.3 is the current synthetic urine product sold by suppliers online today. But does it really work?

Upass 8.3 Synthetic Urine Lab Test Results

Upass claims that their synthetic urine is formulated to pass advanced drug testing. But what does independent lab testing actually show about the effectiveness of Upass 8.3?

I dug into the research to find out.

Lab Study #1: Upass 8.3 Found to be Easily Detected

In 2022, we obtained samples of popular synthetic urine products, including Upass, and tested them against fresh real urine samples provided by healthy volunteers.

The Upass 8.3 was run through validity screening to assess pH, specific gravity, and the presence of common urine compounds. It was then analyzed using additional spot tests and instrumental testing methods.

The study found that while Upass 8.3 mimicked some properties of real urine, it was easily distinguished from real urine with common additional validity tests.

The researchers found abnormalities in the concentrations of various urine components in the Upass sample. They concluded that current validity screening methods are adequate to detect the use of this brand of synthetic urine on drug tests.

Lab Study #2: Upass No Longer Effective

Another lab analysis of synthetic urine products was conducted in 2022 by the cannabis site. They purchased samples of leading synthetic urine brands, including Upass 8.3.

The WayofLeaf testing found that Upass synthetic urine was quickly flagged as fake urine using special validity tests that labs now employ. These include tests for biocides and oxidants that can detect the preservatives added to synthetic urine to maintain shelf life.

The analysis showed that Upass is now obsolete, as labs have updated their methods beyond simply measuring pH, gravity, and creatinine. Additional spot tests like the nitrite, oxidative, and biopsy checks can reliably discern real urine from synthetic formulas.

Based on these studies, it appears that Upass 8.3 synthetic urine is no longer effective at beating standard lab urine drug tests. The formula needs to be updated and can be easily detected by new validity screening methods.

Does Upass Synthetic Urine Actually Work?

Given the concerning lab results showing it can be detected, does Upass synthetic urine work as well as advertised?

The manufacturer claims that Upass synthetic urine mimics real urine and can help users pass urine drug screenings. However, independent research shows that Upass is now largely obsolete and ineffective.

Here are some of the reasons why Upass likely no longer works:

  • The formula needs to be updated – Upass still needs to update its formula to match newer lab drug testing methods as of 2023.
  • Easily detected – Advanced validity screening can identify Upass 8.3 as synthetic urine rather than authentic human urine.
  • Preservative chemicals – Upass contains biocides and preservatives to maintain shelf life that are easy for labs to detect.
  • Creatinine is unreliable – Upass creatinine levels fluctuate and are outside the normal range, a red flag for test administrators.
  • pH fails – The pH of Upass is outside the normal urine range and signals it is not real urine.
  • Adulterant testing – Many labs now also test samples for contaminants, immediately detecting Upass as fake pee.

While Upass synthetic urine may have worked 5-10 years ago, current formulations are now obsolete. The manufacturer needs to keep pace with changing lab drug testing methods.

Directions for Using Upass Synthetic Urine

If you do choose to use Upass synthetic urine despite the risks, it’s important to follow the directions properly to have any chance of success. Here are the standard usage instructions provided with Upass:

Step 1: Verify Kit Contents

Upass synthetic urine kits come pre-mixed in a 3-8-ounce pouch with a temperature-sensing strip on the side. The package will contain:

  • Synthetic urine vial
  • Temperature strip

Before your test, check that both the urine vial and temperature strip are present and intact. Also, inspect the color – it should have a natural yellow urine tint.

Step 2: Microwave and Heat Urine

The sample must be in the 90-100°F temperature range to seem realistic to the tester. To heat it:

  • Remove the cap from the vial
  • Microwave the liquid for 10 seconds maximum – do not overheat!
  • Check the strip to see the temperature change
  • Repeat 1-2x more in 5-10 second intervals until liquid is between 90-100°F

Step 3: Attach and Hide Urine Kit

Once heated to body temperature, you’ll need to attach and hide the kit for your test:

  • Secure the vial and heat pack to the inner thigh with rubber bands
  • Ensure the temperature strip faces outward to read
  • Wear loose clothing to obscure the urine kit during screening

Step 4: Provide Urine Sample

When it’s time for the actual urine collection, follow these steps:

  • Enter the restroom and retrieve the hidden kit
  • Remove the cap from the synthetic urine vial
  • Pour vial contents into a specimen cup

Submit the sample as instructed by the screening administrator. Do your best to act natural throughout the process.

Where to Buy Upass Synthetic Urine

Upass can be purchased from various online stores that sell synthetic urine products and detox kits. Some of the more common shops where you can get Upass include:

  • Official UPass website- Purchase directly from the manufacturer
