How to Keep Synthetic Urine Warm for a Drug Test

So you’ve got your synthetic urine, and you think you’re prepared for your drug test, but then you forgot about one crucial thing: the temperature of your sample

Don’t worry, you’re not alone! In fact, most people tend to forget that incorrect temperature is the number one reason for failing a drug test with synthetic urine. So to help you out, I’ve decided to list down a few ways on how you can keep your fake pee sample warm until you get to your drug test!

The Importance Of Warm Pee

A normal body’s temperature is around 98.6°F (35°C) so it’d be kind of suspicious to submit a pee sample that’s a little too cold to pass off as fresh. When you pee, the temperature of your urine is in between 90 to 100°F (32 to 38°C) – this is the temperature that you should aim for when you submit your fake pee sample. 

You might be surprised to learn that the #1 reason why people fail their drug tests is because they forget how important maintaining the right temperature for their pee is. Not only will submitting a sample at the wrong temperature make you lose your job, you’ll likely be fined or jailed for fraud – so don’t mess around!

How Long Does Urine Stay Warm?

One of the major challenges you face in keeping your synthetic urine warm is the travel time to the destination of your drug test. Synthetic pee doesn’t take that long to cool down, especially if you’re using a normal pill bottle. So if you heat it up in the microwave at home, it might be too cold to pass once you get to work.

In order to help your fake pee stay warm for longer, it’s important to have an airtight container and a source of heat with you on your commute. Besides keeping it from spilling (which is kind of gross, regardless of whether it’s fake or not), an airtight container will properly insulate your fake pee, keeping the heat in for longer.

How to Keep Synthetic Pee Warm

temperature thermometerI don’t think I can emphasize this enough: before submitting your pee sample for your drug test, be mindful of its temperature. Laboratories are constantly improving their technology which means a slight mishap can lead to you failing the test and getting caught!

Luckily for you, synthetic pee kits usually have a heating pad and temperature strips to help you adjust and determine its temperature. Some heating pads work for up to 8 hours, giving you proper reassurance that your pee will be at the right temperature for testing.

However, your heating pad only serves to maintain your sample’s temperature. The first hurdle you need to overcome is actually getting your sample to be at the right temperature – the heating pad can only do so much!


One of the fastest ways you can reheat your synthetic pee is by using a microwave – just make sure that you don’t overdo it. When heating up synthetic urine in the microwave, always remember to use the lowest setting in your microwave and heat up your sample in five or ten-second intervals.

The key here is to take your time with it – it’s better to have pee that’s not heated enough instead of having pee that’s too hot. If your synthetic urine is too hot, it might break down some of the compounds found in your solution, giving different results when tested in the lab and might cause you to fail your drug test. Remember that the goal is to pass your drug test with flying colors so be patient in warming up your fake piss!

Hand Warmers

Hand warmers are the cheapest way to heat up your fake piss. If you’re going to use them to heat up your sample, all you have to do is activate the hand warmers and put your pee sample container next to them until it reaches the right temperature.

Sometimes, one hand warmer isn’t enough. I would recommend buying two just to be sure that your sample heats up quickly. Hand warmers are perfect for transporting your fake pee so that you can be sure that your mixture is staying warm while in transit!

Heating Pad

Most brands usually sell heating pads along with their synthetic urine products which makes it really convenient to use. However, sometimes the heating pad will be missing or might even malfunction, so you should always have a backup method of heating your mixture!

Heating Powder

Some brands sell their synthetic urine products with heating powder instead of heating pads. The powder is usually made of lithium chloride and won’t drastically alter your synthetic urine solution. This method will reliably heat your sample up but exercise caution when pouring the powder into your mixture! Too much will alter the composition of your fake pee, meaning you’ll be stuck with an unusable batch.

Body Heat

Although effective, this is probably the most unreliable way to heat up your sample simply because it’ll take a really, really long time for your sample to go from room temperature to its desired temperature. If you rely on body heat alone, you’ll have to wait for a few hours before you can submit it to the lab. 

If you find that you have no other option, though, then nestle your container in a warm crevice of your body, like the thighs, or armpits; then hope for the best! For best results, you can strap your sample in your underwear or anywhere near your upper thigh using a belt.


Quick Fix: The Best Method for Warm Pee

Because I take my job seriously, I’ve tried and tested almost every method of keeping synthetic urine warm. And, after it all, I’ve found that the most reliable method is actually the heating pad that comes with Quick Fix (click here to read our review of quick fix plus).

You might be sick of me praising Quick Fix on this site, but they really are that good. Not only do they offer high-quality synthetic urine, but the heating pads are really effective. I used a temperature strip to conduct these tests, and Quick Fix’s heating pads kept the temperature at a stable 36 degrees for about 6.5 hours. That’s incredible! That means that you can keep Quick Fix tucked under your belt for more than half the workday with absolutely nothing to worry about.

Quick Fix’s imitation of real pee is astounding and I would personally recommend to anyone looking to cheat a drug test. It’s the most reliable and trustworthy brand out there, so if you want to keep that job and still get high AF on the weekends, look no further than Quick Fix!
