How to Make Synthetic Urine, and Should You Use it?

Last Updated on

Even though we are going to tell you how to make synthetic urine, you should know, right from the start, that we do NOT recommend it.

So why are we telling you then? There is nothing better than knowledge to help people make an informed decision.

Why would someone want to know? Some people may not realize such a thing exists, may not think they can afford to purchase synthetic urine, and don’t want to ask if they can use someone else’s, or think they can do a great job making up a batch for themselves.

Whatever the reason, people will try anything, so we decided to share a DIY recipe with you. Of course, we aren’t going to give you our patented formula. Our synthetic urine is the best in the industry for a reason, and we’re keeping that on lock.

If you want to get into the DIY scene and try making synthetic urine yourself, go for it. But, before we get to the recipe, let’s look at some pros and cons of taking this project on.

Is Making Good Fake Pee, at Home, Possible?

If you find yourself needing fake pee and you don’t want to purchase a pre-made synthetic urine product, you can make fake pee at home. Will it be good enough for your intended use? That’s hard to tell.

Knowing how to make fake pee is useful if you need it and you don’t want borrow urine from a friend or family member. You don’t have to worry about hygiene or health issues if you make up a batch versus borrowing.

But, there could be problems with using homemade synthetic urine unless you are a chemist and this is what you do for a living.

Making synthetic urine that will pass as real urine is a complicated process that will require you to buy unusual ingredients that you can’t find at your average drugstore.

People have tried to make synthetic urine, but only a very few can create a fake pee product that has a good chance of doing the job they intend it to do.

Why do You Want to Learn How to Make Synthetic Urine?

Answer this: How important is it for your synthetic urine to work?

Whatever your reason, you need to take the time to consider what you need it for and how well you need it to work. You aren’t looking for more problems, but a solution. Can homemade fake pee be your solution or could it possibly create more of a problem?

Let’s get to what synthetic urine is and the recipe if you are ready to give it a go on your own.

What Fake Pee is and How to Make it

One more time, we don’t recommend using fake pee that has not been made by a reputable company, but we are going to tell you what it is, why it exists in the first place and how to make it yourself if you really need to.

Synthetic urine is a mix of liquid and multiple components that are found in normal human urine, minus DNA or toxins.

Labs would be able to calibrate urinalysis test strips to be later used in testing human urine as a way of checking for wellness or disease processes related to the urinary system.

Therefore, properly made synthetic urine needed to perfectly match the chemical components of human urine so that it would be able to pass for-real pee.

Properly pre-made products, like Quick Fix 6.2 Plus, have the components needed, the look and the smell that matches real urine, allowing it to pass for real pee more readily. Making your own fake pee has a high potential of not making the cut.

Alright, what you’ve been waiting for: The recipe. The ingredients below should get you a pretty good fake pee. What you see below is similar to the ingredients that you would find in professionally made synthetic urine products.


  • 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

Before you get started, make sure you have a good kitchen scale. If you are trying to make passable synthetic urine, you need to have the tools required to play kitchen chemist, or you might as well scrap the whole idea and just buy a good product.

Let’s assume that you were able to get the ingredients listed above and you have a good kitchen scale and a 40 oz container with a suitable sealing cap. The “putting it all together” needs to be as precise as possible.

  1. Measure all of the dry ingredients, as accurately as possible, and put them into the 40 oz container.
  2. Start adding the wet ingredients. The last liquid component, to add, will be the 0.02 M HCl solution. Add the HCl solution slowly, while continuously mixing your solution. This solution is going to determine the color of your fake pee, and you may not need to use all of it. When the color of your fake pee looks good to you, you have used enough.
  3. When you have completed step 2, you are done. Cover your container and store it in a place where it will not be exposed to extreme temperature changes or direct sunlight. It should keep for a while.

The above recipe may seem quite simple. You may be thinking, “I can do this,” and you may be able to pull off a passable product. But remember, only a few people, learning how to make synthetic urine at home, can create a product that can match professionally made synthetic urine.


You now know how to make synthetic urine. Before you take the time to find the ingredients, stress about putting it all together and wondering if it will work, consider the money, stress and time you will spend making it yourself vs. buying a professionally produced synthetic urine.
