How to Make Clean Pee at Home

You may be wondering why anyone would experiment with making a fake pee at home when you can find synthetic urine in any local market or online store. People have odd hobbies and interests; so why not spend some time in making artificial urine? Maybe someone likes chemical experiments or possibly expect a drug test soon.

Either way, artificial pee can be made at home with all the necessary ingredients and equipment. There are some components that you can get out of the recipe if you need clean pee for home use. Then you don’t have to think about the color or the temperature or pH of the urine (normal level find on this page). However, this experiment becomes more demanding if you want to use home-made pee for cheating a urine drug test.

Fake Urine Recipe


One warning at the very beginning – there are many versions of recipes for making home-made fake urine on the Internet. They all have more or less the same components. However, their ratios can vary. But users praise all recipes, so you probably won’t go wrong with any of them.

Before you start making a fake pee, you need the right equipment. Home-made experiments should be easily feasible, with what you already have at home. We doubt that pH meter and urinometer are essentials in your household items. But if you plan to make fake urine experiments from time to time, these instruments will need you. Also, you need a storage bottle and a sterile mixing container.



If you have a pre-knowledge of chemistry, you know that urine consists of almost 95% of water. The rest is a solid matter that gives it specific characteristics. So, for starters, you need distilled water. You can’t use sink water because it initially has its chemical composition that can disrupt your entire experiment.

Then, follow the list of powdery ingredients. You need uric acid, urea, and creatinine and albumin powder (non-obligatory for home use of fake urine). Then, there are ingredients you may have never heard of, at least not according to their professional names – sodium chloride, potassium chloride, calcium chloride, and magnesium sulfate. Does sodium chloride ring your bell? It’s just salt that we use in everyday meal prep, but with the addition of some other compounds. So don’t use the kitchen salt in your fake urine.

Most of the ingredients used in these experiments are in a powdered form, and you need a very accurate kitchen scale. The exact amounts will depend on which recipe you opt for. But in any case, you have to adhere to the recipe to the T, which means that the measures must be precise to a milligram.



The good thing about home-made synthetic urine is that you can store it and even freeze for several months. So make a little extra quantity; you never know when you need it.

The containers you will use to make and store the false urine should be sterile. On the link below, read how you can do that at your home:

First, add urea and urine to a certain amount of lukewarm distilled water. Mix until the crystals completely dissolve. Then add all other powdery ingredients. It is best to mix them all, and swiftly add them to the prepared solution. Stir another few minutes; leave it to rest. If you need artificial urine for home use, your experiment ends here. You can place it in a storage container and put it away until use.

Extra Effort for Making fake Pee for Lab Drug Test


However, additional ‘settings’ are needed if you need a fake pee for a drug test performed in a lab. Now you need the instruments that we have already mentioned – pH meter and urinometer. First one measures the acidity of the sample, while the second one determines the specific weight of urine. These are two parameters that are necessarily tested on urinalysis. Any deviation carries the risk that lab technicians can reject your sample as invalid.

In this situation, you need creatinine and albumin powder. Add these immediately before using the sample, after heating it to the optimal temperature. Do not heat the fake pee in the microwave; use specially designed heating stripes or pads with indicators of the right temperature.

Is This Experiment On Budget?

Well, not really. Home-made fake pee experiment is not cheaper than commercial synthetic urine. When you add the prices of all ingredients, but also the spent time, you realize that a more economical option is buying clean urine. Also, you may have problems finding the chemical compounds that you need for fake pee. If you live in a larger city, this is not a problem. However, in a small environment, pharmacies are not well supplied, and specialized stores where you can find these ingredients do not exist.

Can Fake Pee Help You Pass a Drug Test?


Making a fake pee at home can be both fun and useful activity for teenagers, for example. If they have strict parents who want to test them for the presence of opiates using simple home tests, home-made artificial urine will undoubtedly pass it. The reason for this is simple – home drug-test detect only the presence of substances. There is no way to check the validity of the sample (unless your parents supervise the sampling process, i.e., watch you while peeing).

On the other hand, for a passing urine drug test carried out under laboratory conditions, the use of home-made fake pee can be too risky. Collectors and lab technicians are trained to recognize an invalid sample, even without testing. They just have to look at the color or check the optimal temperature. So do not rely too much on home-made products if you have a real drug test announced.


Faking a drug test already carries a particular risk. You can try to sneak the irrelevant sample in, just to buy some time. But you must prepare for the repeated test. It can happen very quickly, perhaps on the same day. Always have a backup plan and do not rely entirely on DIY experiments.
