How to Preserve Synthetic ​Products
Properly Storing Your Stash

preserving artificial urine

If you want to pass off synthetic ​samples as human successfully, you must do your part to ensure the ​product is as similar to fresh human urine as possible. The money has already been spent on the product and the decision to use it has already been made, so you might as well put the energy in to confirm that it will be preserved correctly for whatever you need to save it for.

The most common error in using an artificial product is the failure to properly preserve the sample beforehand. Customers may think that once they have the product, they are good to go. Unfortunately, that is not the case for all of the products. The sample must be kept according to certain parameters to preserve both the correct temperature and color. If not properly preserved, there may be red flags raised about the authenticity of the sample.

Synthetic Urine Storage Tips 101:

​Fake pee after purchase will remain at the temperature of its environment. If kept in a hot car, it may overheat. If put in the refrigerator, it will be cold. It can also change color over time if not kept properly. The goal is to have it match as closely to human pee soon after leaving the body. For that to happen, it must be a specific color and temperature. Otherwise, an at-home drug test will be able to detect that the sample is a fake. To save money and heartache, doing it right the first time is the best option.

What are the Proper Preservation Techniques?

A properly preserved synthetic product right before use should be similar in temperature to the human body and within a reasonable range of the color yellow. It should not be too hot, and not too cold. These are dead giveaways that the sample is not human and should be avoided at all costs. There are brands of synthetic ​samples that are easier to store, you can see them here.

Once you have your product preserved, you’ll want to keep it in a safe place of mild temperature until ready to use. When you’re ready to use it, warm the product up and check to make sure it is a natural-looking color. Keep it close to your body to preserve the heat until you need to submit your sample.

What Temperature and Color Should It Be?

The human body temperature is normally at 98.6°F. After leaving the body, human urine should range from between 94°F and 96°F. Since the temperature can dramatically change soon after depending on the temperature of the surrounding environment, a urinalysis must check the temperature of the sample within the first four minutes after the sample is collected. The range of acceptable temperatures is between 90°F and 100°F, and if the sample falls outside of that range, it will be extremely suspicious.

Pee can change color as time passes. Human urine after exiting the body should be yellow. Diluted urine will have a lighter color and will be a red flag. Do not mix the synthetic product with water or add anything to it. A common mistake is diluting the product and even adding B vitamins afterward since it adds a yellow coloring. The high level of vitamins and low concentration will still be detected, so it’s not a good idea. Ideally, the synthetic product should be within the same parameters of color as human urine.

Methods of Heating/Reheating After Preserving:

While there are multiple methods that can be used to heat a synthetic sample, some methods are better than the others. While microwaving is the quickest and easiest way to raise the temperature, it creates some issues in getting the exact right temperature and preserving it until the test. Hand warmers and body heat take more time and have more variables involved, but tend to give a more accurate temperature reading.

1. Microwave


Microwaving the sample is a quick and easy way to raise the temperature. Simply put, the sample into a microwave-safe container and heat in increments of 10 seconds. Use temperature strips after 10 seconds to test the resting temperature. If not warm enough, heat for another 10 seconds and repeat this process until safely in the range between 90°F and 100°F.

You’ll want to be careful not to overheat it though because that makes things a bit tricky. There’s always the option to let it cool down to a proper temperature, but it should be noted that sometimes overheating the product can ruin it by breaking down the molecules. To be on the safe side, microwave it in short spurts and test the temperature after each time.

2. Handwarmers

Hand warmers are small, readily available, relatively easy to hide, and efficient in heating a sample. Take a good look at the details on whichever brand of hand warmers you have to see how fast they heat up and how high they are capable of heating. Warmers that will keep the heat in the range between 90-100°F are ideal. Knowing what you’re working with will help you avoid overheating and ensure the heat will last until needed for use.

When using hand warmers to heat the synthetic product, pour the product into a plastic bag or small container and seal it. Wrap the warmers around it, and secure in place with tape or a rubber band.

3. Body Heat

The last available option is merely taking advantage of body heat. For men, it’s popular to keep the sample near the crotch or inner thigh, secured with a band or tape. For women, the sample can be kept in the underarm, near the breast, or near the crotch.

Body heat can fluctuate and at times, can fail to heat the sample as high as it needs to be. This method could require some practice beforehand to be sure the ideal temperature can be reached.

What is the Best Option?

Using your own, clean urine is always the best option. When that’s not possible, Quick Fix Synthetic Urine is the next best bet. Using body heat, hand warmers, or microwave to reach the proper temperature for a urine sample, you can ensure that your synthetic product passes as the real thing. Just be sure to keep the synthetic product properly preserved to preserve the most foolproof color and temperature possible.
