Synthetic Urine: The Definitive Guide to Fake Urine
Thursday, Mar 7, 2019

So let’s start with the basics, what exactly is synthetic urine? More commonly known as “fake pee,” people also call synthetic urine laboratory urine. It is a substance created to mimic the appearance, chemical properties, and, most importantly, the composition of human urine. All of the major components of natural urine can be found in synthetic urine, including (among other things) creatinine, uric acid, urea, ammonia, and sulfates. Even the pH level and specific gravity in “real” and synthetic urines are nearly identical.

Fake pee is available in a few common forms. This includes dried powders and pre-mixed solutions. Both of these forms expire with time. Therefore, replace any unused kits lying around for a while.

Synthetic Urine: Factors

So what is synthetic urine made of anyway? Basically, it’s a liquid that has been scientifically mixed to form a urine-like sample. Here are four main components to be considered:

Color– It goes without saying that “fake pee” cannot just like be any old liquid, and it certainly can’t just be any color. Thankfully, chemists have figured out how to make it look exactly like real urine. It’s nice usually a nice “warm” yellow-ish, and is anything but colorless. Creatinine level– Chemists include minimal solutions in fake urine for it to be like that straight out of the body. This is because minimal creatinine levels can’t be a factor to make urinalysis positive. Temperature– Chemists first check the temperature of actual urine, and then add chemicals for the liquid to appear authentic. pH Level– Measured from original urine, certain components are then diluted to make it appear original. It’s then tested and improved in the mixture.

There’s no doubt that synthetic urine is the fastest and most effective way to pass a urine test. However, there is actually much skill and a decent amount of risk involved. This is because you have to smuggle the fake pee into your test and/or switch the sample with your actual urine.

Uric acid– Since normal urine contains uric acid, most labs will test for the presence of it when carrying out a drug test. This is why it is vital that you ensure that the product contains uric acid when you purchase synthetic urine. Always check the label of the product. Trusted dealer– The increased demand for synthetic urine has caused a significant increase in counterfeit products — “fakes,” if you will (no pun intended). Always do your research and don’t fall into the trap of unscrupulous dealers. Only by the best (i.e. don’t be afraid to spend a few extra dollars) and check out the feedback that has been given by people who have used that specific brand. Temperature– The temperature of urine is approximately 36-37C, or 95-100F. Thus, the synthetic urine must have a temperature that is very close to real urine. The best products come with a heating pad to keep the urine warm, and also a special strip that displays the current temperature. Shelf life– Drug tests usually pop up unexpectedly. If/when you are told to do the old “pee in a cup” routine, you want to make sure your urine hasn’t expired. Synthetic urine has an expiry date, and therefore you should always ensure that you have an extra bottle with a long shelf-life nearby, or at the very least replace your urine periodically with a fresh one. Animal repellent– Garden enthusiasts use animal repellent to keep rodents out of their favorite plants. Synthetic urine works just as well as the real thing and brings down the overall costs for gardeners. Pranking your friends– This is the most entertaining reason to use synthetic urine. For people with a little extra time on their hands, this might be a “fun” little prank to mastermind. Education– Medical students all around the world train using synthetic urine. Typical training includes urinalysis tests and clinical experiments. Cleaning agents testings– Fake urine is very popular among salesmen and marketers. They use it to demonstrate the effectiveness of various cleaning agents; especially for carpets and furniture that need urine stain cleaners and odor removers. Sounds gross, but it’s the truth. Science– Scientists use synthetic urine for a variety of different scientific purposes; from preparing for Mars missions to development of new urine tests for different diseases.
