If you feel less than confident your urine will pass a drug test; you do have another option – synthetic or fake urine. Yes, it exists, and it does work. But, it isn’t as simple as pouring it into that little jar, marching over to the healthcare official, and sitting pretty. Or is it?

We will give you the rundown on how to pass a drug test with synthetic urine right here.

What Is Synthetic Urine Exactly?

Your actual urine is made up of certain components and mimicking these is what synthetic urine is all about. You may ask, “Is it possible to duplicate urine? Surely that is impossible.” Well, your questions are very valid; however, to pass a drug test, the test requires certain areas to be covered, for it to be deemed passable real urine. Synthetic urine aims to cover those areas.

You may wonder where synthetic urine came from and why it was invented, to begin with; oddly, not because of the need to pass a drug test. Friedrich Wohler of Germany, a chemist, back in the 19th Century, was trying to create ammonium cyanate in his laboratory when his concoction passed as urine after a few tests.

As for the actual makeup of fake urine, it covers these bases, regarding real urine:

  • 95% of the liquid is water
  • 5% is made up of creatinine and urea

Other substances that are added to the 5% are:

  • phosphates
  • ammonia
  • sulfates
  • chlorides

In essence, the PH balance of the liquid must be between 5 and 10.

The gravity must be anywhere between 1.003 and 1.035.

You will find that the different manufacturers will have their unique formula and recipe. So, no synthetic urine available on the market will have the same makeup.

The synthetic urine often does not come in a liquid format, but in a powder consistency, which you need to dilute. The liquid option is better in that it is ready to use, however normally requires you to heat it before handing it over. The reason being is that the urine that exits your body has a certain temperature, which needs to be mimicked in the fake urine. As for the powdered option, you would use water to mix it up, and sometimes they come with a heating agent as well.

Also, the manufacturers also mimic the color and smell of urine to give it that natural look and feel.

Does Synthetic Urine Work For Drug Tests?

In a nutshell, yes. Should you be going for a general, run of the mill drug test, say for a job interview or even medically necessary testing of some sort, the chances of them detecting that the synthetic urine isn’t real, is very slim.

If the tester wanted to take it a step further, it would cost them a pretty fortune. General urinalysis testing kits won’t pick up that the liquid isn’t the real deal.

For further peace of mind, ensure you buy a quality product off the market and know how the test will be administered. In this we mean, ask upfront how the test will be taken, i.e., will you be alone, will you be able to drop the urine sample off, or will you be monitored at all times? These factors can hinder you utilizing synthetic urine for the test.

Why And When Fake Urine Is A Good Idea

There are many reasons to use fake urine and not only for a drug test, however, but we will also cover why and when it is a good idea to use it.

Alternative Medicine And Cosmetology

When it comes to the beauty industry, fake urine is often used for testing purposes. And for alternative medicines, urine therapy requires the use of urine. Therefore fake urine works better.


In the process of testing for disease and cures, synthetic urine often forms part of the process.

Testing Diapers

Manufacturers will use fake urine to test their diapers, to ensure they can safely market their product to the public.

Cleaning Detergent Testing

The salesman will often use fake urine in the demonstrations for their cleaning agents, i.e., Urine stains and odor removal


When out hunting, hunters will use synthetic animal urine, which has a slightly different nuance to human urine. This attracts the prey to a certain area, making it easier for them to get their aim in and get their shot.

Passing A Drug Test

The obvious one, some would think, is to use synthetic urine to pass a drug test. If used correctly the success of passing a drug test can be possible when substituting real urine with the fake urine.

When it comes to drug testing, not every situation will work with regards to using a synthetic urine kit, so be aware of how the test will be run.

Can Labs Detect Synthetic Urine?

Yes, most times it is. The labs follow a simple testing process, and only if they think there are suspicious elements will they conduct an adulteration test. The first and foremost check for the drugs within the urine, and not whether the urine is real. The products on the market nowadays are that good that they are undetectable by most adulteration tests.

How Do You Use Synthetic Urine?

Very simply, you need to get the synthetic urine into the sample cup or jar for the tester to believe it is your urine. Without raising suspicion, and following protocol it is possible to fool the test.

This is how it generally works:

  • Purchase the synthetic urine from the store or online
  • Take the kit with you to the testing area or do the deed at home
  • If in a liquid format, all you need to do is warm the liquid up. This can be done with a microwave, heating pad or using your body warmth
  • If the product is in a powder format, you need to dilute it with the recommended amount of water, and normally there is a heating agent in the packet as well
  • Once you have followed the instructions, pour the liquid into the sample cup
  • Then hand the liquid to the tester or lab

Should you find that the urine test will be held with a monitor, then you will need to buy a kit that includes a synthetic urine belt or a prosthetic device that looks like a male or female organ.

It is also important to get the sample urine to the tester before the temperature drops too much.

How Can You Hide Fake Urine During A Drug Test?

There are many ways to hide fake urine on your person to utilize it during a drug test:

  • Utilize a belt to attach the fake urine container to
  • Buy a synthetic urine belt online which is built to carry the liquid inconspicuously
  • Taping a sachet of fake urine to your inner thigh under a loose dress or pants will work too
  • Anally or vaginally may work, so long as you make a desirable method of pulling the container out

What Temperature Should The Urine Be And How Can You Heat It?

Normally urine that leaves your body is around 94°F (about 35 °C), and most times the urine is tested within 4 minutes of being received. There are ways to heat your urine. Generally, a microwave does the trick, but don’t overheat it (having a thermometer handy will work best), or using your body heat to warm it up can suffice.

How Long Is Synthetic Urine Good?

Like with most synthetic material the shelf life is generally a year to two years. With the fake urine on the market, the two-year marker is how long you can keep it for, however, check the packaging, and ensure you store it in a dry, out of the sun area, or you will throw off the PH balance.

How Do Labs Test For Drugs In Your Urine?

The labs first put your urine through a test called EMIT, which stands for Enzyme Multiplied Immunoassay Technique. This tests for any drugs and high levels of protein.

Also, they test the color of the urine, to make sure it is the required color that urine needs to be. They use a color spectrum for this purpose, as urine can come in different colors, dependent on your level of health and age.

Further, should your urine test be positive, they will send it for a further similar test, but this time to ascertain what drug is present in your system. A GC-MS machine is used, which is a Gas Chromatography-Mass Spectrometry. This tells the lab what illegal substances and their metabolites are hanging around in your urine.

How Do Labs Test For Synthetic Urine?

Should they be suspicion, the labs can send your urine for further testing to ascertain whether the urine is human.

They look for the following:

  • That the pH level is between 4,5 and 8
  • That the gravity level is between 1.005 and 1.030 – this measures the density of the urine as well as a concentrate of solutes within
  • That the creatinine levels are above 15 mg
  • That there isn’t Glutaraldehyde present in the urine, as this is an obvious mix from synthetic urines
  • That there isn’t Nitrate present for the same reasons as above point
  • That there isn’t increased volumes of urea present, which indicates that it is fake urine
  • Color and odor is measured against set parameters
  • Temperature, if taken quick enough to test can also be factored in to see whether the urine is real or not

So, there you have it. The low down on synthetic urine and how to pass a drug test with this clever substance.
