Synthetic urine


What is synthetic urine?

Synthetic urine is an artificial liquid that imitates the composition, chemical properties, and appearance of human urine. It is used to help researchers do thorough chemical analysis of urine. Since human urine significantly differs in all parameters, there is no specific sample with which to calibrate equipment. As a matter of fact, there is a range which human urine should fall into.

Synthetic urine is used for the calibration of urine screening equipment, as a novelty product, a fetish product, and as an animal repellant.  To accurately calibrate urine screening equipment, synthetic urine must contain a long list of perfectly balanced substances like uric acid, urea, nitrates, and water among other ingredients. 

Does synthetic urine work in the lab?

The short answer is yes, it does. The typical urine screening equipment normally checks urine for certain toxins, commonly found chemicals in human urine, and if the sample has been adulterated or diluted. In order to accurately calibrate all parameters of the testing equipment and to provide a “negative control”  a consistent synthetic sample must be used.  Traditional lab equipment commonly checks for proper pH and creatine levels, specific gravity, temperature, and urea.  Recently, modern labs have added another parameter in their testing, uric acid.

How much fake pee do you need?

On a normal occasion, 2oz would be quite enough. The regulations collector of the US Department of Health and Human Services has to accept this amount if the donor isn’t able to provide more. There are cases in which more urine is needed, for instance, if a spill takes place, or if you want to avoid any attention from the collector. To avoid any questions and to cover all situations, use a 3oz bottle.

How to keep it warm?

One of the most common ways to keep urine warm is to use a microwave. After heating it up at home, you need a proper way to keep it at room temperature. You can do this by using a heat pack that is common in popular commercial products. These packs can store the temperature for approximately 8 hours. The simple way to warm the urine is to use your body heat. For example, you can place a rubber band to attach the bottle to your body on your inner thighs, bras, armpits or underwear. Or you can wear the heating pad in the same way. This is a very good technique when it comes to results but it can get uncomfortable if you wear it the whole day.


Fake urine has this specific advantage – it can be stored for years, unlike real urine. Most fake urine has a shelf life of between 2-3 years, and does not need any maintenance tricks like cooling or freezing. Reheating is also simple e.g. with hand warmers and can be repeated for an unlimited amount of times. Fake pee can be reused!

Does it work?

To answer this question, one needs to understand its different applications. Labs are the primary users of synthetic urine. Organizations like remedy testing labs, researchers and institutions use it for calibrating their remedy testing equipment. The accuracy of equipment is provided by testing samples of urine that were mixed with chemicals or other toxins. It is hard for these institutions to use real urine because of its bad smell, it also foams and can decay if it isn’t frozen when it is shipped. Additionally, when taking urine samples, the donor has to go through various tests to check for diseases and other remedies in the body. Finally, everyone has a unique body chemistry, so different urine compositions are usually prepared for different people. Synthetic urine was made to avoid these problems.
