Can You Reuse Synthetic Urine? How Long Does It Last?

Synthetic Urine is very useful when you need to pass a drug test. However, sometimes getting the timing right can be very difficult. So what happens if you heated up too early? Can you reuse that same bottle or do you need to buy another one? And how long can you even hold onto synthetic urine?

Can You Reuse Synthetic Urine?

The answer is yes, you can reuse synthetic urine after you have opened the bottle. Firstly, always try to keep it in a cold place (your freezer or fridge works well). This will stop the metabolites and chemicals from degrading until you actually need to use them.

However, be careful … because it needs to be heated back up to human body temperature so that the testing labs initial temperature testing comes back ok. If it is not at the correct temperature, then you may fail the drug test.

So if you are in a pinch and need to reuse fake urine, make sure that you freeze it when you aren’t in need of it and then when you do – make sure you heat it up correctly and to the right temperature. Otherwise, your drug test results may come back negative and you will be out of luck.

A handy trick during the day of the test (if you don’t know the time) is to buy some hand warmers and tape them to your thigh. This will keep the bottle at a good human body temperature throughout most of the day.

How Long Till Synthetic Urine Expires?

Another common question is how long does fake urine last? The answer will vary depending on the type of synthetic urine you are using. Most high-quality brands (like the ultra klean ultra pure synthetic urine) contain around 2 years validity (how long they can be used before expiring), but this really depends on the density of the urine and how it is stored (in a cold place).

If you can keep the bottle in your fridge, then that will help prolong its life; however, always check with your supplier first about storage conditions. It is also important to remember that some people believe they can tell when drug testing if your sample has gone bad because it might smell like ammonia (and according to them, it smells like ammonia then you should fail the drug test).

However, this is not always the case and most labs only test for certain chemical levels – not smell. So if your urine sample smells like ammonia, it might be bad but it’s not always a guarantee that you will fail the drug test.

Final words

In short, you can reuse synthetic urine after you have opened the bottle, but make sure it is at the correct human body temperature when taking the test and stored in a cold place when not in use. How long fake urine lasts really depends on the quality of the product but usually ranges from 2-3 years. If it smells like ammonia, it might be bad but this is not always a guarantee that you will fail a drug test. Always check with your supplier first.
