Last Updated on

Getting a positive result on a drug test is one of the worst experiences that could ever happen to any adult. There are a lot of consequences to failing a drug test, like losing employment opportunities, getting fired, maybe even going to jail. Not to mention it’s also embarrassing as hell. 

Not everyone has the time to detox and flush out their systems, especially with on-the-spot random drug testing. To work around this, some people use synthetic urine to pass their drug tests. Fresh samples are always the best and most reliable, so ideally, you purchase the fake pee and use it right away. Some companies even offer next-day delivery which is super helpful when you don’t have much time to prepare. But things happen; maybe your test got canceled and now you’re stuck with a bottle of fake piss. Perhaps you’re just stocking up in case of emergencies. Either way, you might be wondering, “will this expire? And how long will it last?”

How Long Does Artificial Urine Last?

They usually last anywhere from a few months to three years or so, but it depends on the product, the manufacturer, the formulation, and the storage conditions. Clear Choice Sub Solution, for instance, being one of the best fake piss (read more), will stay good for about 24 months. There are a few ways to take care of your sample for the most reliable results, like storing it properly, avoid exposing it to extreme temperatures, and of course, using it as soon as you possibly can. Storing it incorrectly could cause it to go bad way before its actual listed expiration date.

No matter what, you should never use expired pee for a drug test! Synthetic urine should contain the right pH balance, levels of creatinine, and specific gravity to fool the labs into thinking it’s real human pee. Once it’s past its expiration date, its quality deteriorates and it becomes much easier to spot that it’s fake. Using expired piss will compromise your test results, raise suspicion, and put you at risk. Even worse, you might have to do it all over again – this time, supervised!

Always use a fresh sample so that you are confident and free from anxiety. Follow our tips and tricks to make the most out of your fake pee.

Tips & Tricks to Keep Fake Pee Fresh

Store in a cool, dry place, out of direct sunlight

Leaving your bottle of fake pee out in the sun is a sure-fire way to mess up its pH balance and cause it to expire much quicker. Always store synthetic urine in a cool, dry place, out of direct sunlight. We recommend storing it in the fridge.

Do not open unless necessary

Fake pee degrades once it’s exposed to oxygen, so think twice about breaking that seal until you absolutely have to. If you have to open it for whatever reason, make sure to store it in an airtight container after to preserve it.

Do not reheat and re-cool it multiple times

Some brands of fake urine can be affected by extremely hot or extremely cold temperatures, as well as rapid cycling between the two. Keeping it at a stable temperature will prevent it from expiring too soon.

Run a validity test strip

If you can get what they call an “adulteration test strip”, you can test if your pee is still good or not. It will check if the pH balance, creatinine levels, and other urine components are at normal human levels.

Use a reliable synthetic urine like Quick Fix

Everyone agrees that Quick Fix is one of the best synthetic urine kits out there according to Score Loop’s rating. It’s not affected by extreme temperatures and it has a solid shelf life of around two years.


There’s nothing scarier than facing a drug test unprepared. If you need a fast, easy, and reliable solution, synthetic urine is the way to go. As long as you follow our tips and tricks above, your bottle of fake pee will last a long time so that you can take advantage of it for as long as you can.
