How To Make Your Own Fake Pee For A Drug Test

At first it sounds like a silly idea to try and make your own fake urine at home, but as soon as you consider the idea of asking someone for and then using their pee, it seems a lot saner. One of the most searched phrases online is "how to make fake pee."

Fake pee can help you avoid the social awkwardness and potential hygiene issues of using someone else’s pee. It does however present other problems.

Making passable fake pee at home is a really hard process that requires a number of specialty ingredients. Among people who have attempted this, very few come out of it with a pee substitute that they can trust to do the job.

If you are here reading an article about making fake pee, then I know you are desperate for a solution. Fake pee could be your answer, but making it yourself really reduces your chances of success.

What I want to do here today is give you a heads up on what synthetic pee is, how it works in testing and how you could make it yourself if you are game.

To be clear, I don’t recommend homemade, but I want you to know that option is available if you need it.

How does Synthetic Urine Work?

Synthetic urine is a chemical mix that is designed to replicate exactly the composition of human piss. If it is well made, not only does it look and smell real, it will also pass through your average urine testing equipment without a problem.

There are a number of recipes out there, but what you want is one that creates the right smell (by using ammonia) and the right PH level.

Below is my recommended chemical list for synthetic pee. You will find that this is very similar to the compounds found in professional offerings.

How Drug Testing Works?

Drug testing via urine is probably the single most popular way for employers to screen their employees for drugs in both the public and private sector.

It is relatively cheap and easy to conduct these tests and they can be quite accurate, but by understanding how they work you can fool them.

First of all, testers insist on fresh samples to eliminate the chance of substitute urine being used. Some test centers even monitor you while you are giving the sample.

Luckily, there are products on the market such as the popular Monkey Dong, which allows you to deliver fake urine in a discreet manner, even while under observation.

The next hurdle is temperature. After the sample is taken, its temperature is monitored. This is the single easiest way for the tester to detect fake or substitute urine. Pee that is not fresh or the right temperature will make the test invalid and really drop you into the deep end.

Finally, it comes to the actual testing of the sample. The tester uses a simple kit to detect traces of drug compounds in your pee. Virtually any drug you can take will pass through your pee and will be detected. This is of course, where the fake urine comes in.

As discussed already, you can make your own, however I think a much better option that also gives you peace of mind is purchasing pre made synthetic urine like Quick Fix. You can also read our article on what the best method is to pass a drug test


What is the Recipe for Synthetic Urine?

As you can see here, this is not a simple fake urine recipe and to get it right at home you 100% need the right ingredients. If any are left out, you will not get passable fake piss.

Also, I would not recommend even starting unless you have an accurate scale for small quantities. The quantities listed are small and need to be measured accurately, or the final product will not have the correct chemical mix.

  • Approximately 33 oz of 0.02 M HCl solution.
  • 1.9ml of 25% v/v solution of ammonia.
  • 14.1g NaCl
  • 2.8g KCl
  • 17.3g urea
  • 0.6g CaCl2
  • 0.43g MgSO4

Step by Step Guide

OK, so if you got this far then you probably haven’t heeded my warnings – or you are a budding chemist – and you want to have a go at making synthetic urine for yourself.


Learning how to make synthetic urine can be tricky​ but​ here are the steps.

The first step of course, is to gather the materials listed above, which on its own is no
easy feat. Let’s just assume that you have them though.

The next steps are not too difficult.

  1. Accurately measure all of the dry ingredients and place them into a container that has a capacity of around 40oz. something that you can carefully seal would work best.
  2. Next, begin adding the wet ingredients, finishing with the 0.02 M HCl solution. Add this solution slowly while mixing. You may not need to use it all. Judge for yourself when the color of the urine seems correct.
  3. You should be able to keep the synthetic urine stored for some time, as long as you do not expose it to extreme temperatures or direct sunlight.
    These relatively simple instruction hide the fact that very few people actually manage to get the ingredients together, or measure them in the correct quantities.

The real problem is there is no way to tell that you mixed everything correctly until the day of the test, where you risk being found out!


The Verdict: Can You Really Make Your Own Synthetic Piss To Pass A Drug Test?

The answer is clearly yes, you can certainly make your very own synthetic urine. But should you? I think that anyone with any kind of common sense would say no.

With the hassle of finding all of the necessary chemicals, the problems in measuring the correct quantities and the very real and large risk of messing it all up and being caught, it just isn’t worth it.
