How Long Does Synthetic Urine Last or Go Bad?

If you have a urine screening coming up, you might be wondering about the Quick Fix Synthetic Urine you bought some time ago.

Is it still good? How long does it last? Well, set your fears aside – QuickFix has the longest-lasting shelf life in the industry.

Does Fake Urine go bad? What can affect my product?

Storing your fake urine incorrectly can cause it to go bad way before its actual expiration date. There are 3 main factors which could negatively affect your product:

1- Sunlight

2- Exposure to oxygen

3- Extreme conditions.

1. Sunlight 

Sometimes when people move stuff around, they forget to store things at appropriate temperatures.

Having the fake pee in contact with direct sunlight will negatively affect the pH levels in the urine; which can, in turn, affect your urinalysis results.

If you accidentally leave it out exposed to sunlight for a short amount of time—a couple of minutes or an hour—it will not affect it; however, leave it out there for more extended period of time, you might want to talk to someone at Quick Fix about what next steps you should take.

2. Exposure to Oxygen

Another factor to consider is its exposure to oxygen. On many different boards and websites, people ask the question as to whether they can use fake urine if they have already opened it.

Say, for instance, you took it to work thinking that your urine screening was going to be that day, opened it to check the pH or creatinine levels and then you found out that your testing won’t be for another few days or weeks. What about the product that you already opened? Will it be okay for your next urine screening?

The answer is yes. However, the quality of artificial urine (regardless of which brand it is) can deteriorate the pH levels substantially if left open and exposed to oxygen and particles in the air. So if you are using fake urine, please remember to seal it properly whenever you are not using it.

3. Extreme conditions and temperatures.

The best option would be to store your QuickFix product at room temperature, with no direct access to sunlight. So as long as you are keeping your artificial urine in a room where the temperature is between 68 degrees and 75 degrees, you will be in good shape.

Can you refrigerate urine?

We do not recommend that you refrigerate it and do not put it in the freezer.

Does Synthetic Urine expire?

The answer is yes – like any other product, fake urine has an expiration date. This varies depending on the product or the manufacturer, but QuickFix boasts of the longest lasting shelf life.

This means that our urine can be heated and cooled without affecting its ingredients within a two year period.

After this period of time, your artificial urine will expire – its quality, pH and creatinine levels will deteriorate, and it will be easier for a lab technician to spot that the sample is fake.

If your QuickFix product is expired or goes bad, you should NOT use it for screening, as it will compromise the results.

Since QuickFix can last two years, it’s important to verify that you are still within the time frame. So for your protection, and for a successful result, we tell you the manufacturing date of your product.

You’ll find this information on a green insert in the package. You won’t see an actual date, however. What you’ll notice is the batch number with a code.

Verify with the Lab

The batch number of your particular product is on the left side of the directions on a green piece of paper or as of recent printed on the actual urine sample bottle. Don’t throw this insert away, since it contains your step by step instructions.

You can verify your batch number and get the exact date of manufacture by calling the phone number for Spectrum Labs, and they will give you the expiration date. We do recommend you verify each batch before you use it.

Tips to Make Your Fake Urine Last Longer

Here’s a summary of our top tips to keep your fake pee fresh and preserve its shelf life:

  • Store it in a cool, dry place 
  • Keep it out of direct sunlight
  • Don’t refrigerate it or put in a freezer
  • Don’t expose it to oxygen
  • Always check your batch number 
  • Stay away from counterfeit products 


Does urine get cloudy when refrigerated?

Yes keeping a real human urine sample in the refrigerator can turn it cloudy but it won’t have any effect on the sample and is likely to pass a test. If you are using someone else’s piss to pass a urine test and it is cloudy it could be because of bacteria.

The best option if you are going to store genuine urine for any length of time is to keep it frozen, this will lessen bacteria growth. Bacteria will start to grow after 24 hours even if the sample is refrigerated while keeping it in the freezer it should remain growth free indefinitely.

The safest bet is to use fake urine, as it won’t go bad and will last a much longer time and its certainly more hygienic! It’s also said that lab technicians who regularly carry out these urine tests have a nose for stale pee. If you want a better chance of passing then use a laboratory designed option such as QuickFix.

Can you still use expired QuickFix urine?

No, you shouldn’t use expired QuickFix products, as it is likely that the quality of the product’s ingredients could have deteriorated making it easy for a laboratory technician to realize the sample isn’t genuine. Having the wrong pH balance and creatinine levels will raise a red flag and the probable scenario is you will fail or be tested under supervision the second time.

QuickFix has a shelf life of two years which is longer than other fake pee brands. As we discussed earlier you can find the batch number on the bottle to ascertain if it is genuine and within its expiry date.

Can I store fake pee in an opened bottle?

It’s advised to keep save artificial pee in an airtight container. Subjecting it to oxygen can accelerate its deterioration, and reduce its life span. Fake pee is usually packaged in airtight pouches to avoid this issue and prevents oxygenation.

Can you reuse Fake urine? 

Yes, you can reuse and reheat it multiple times this will not be an issue with QuickFix. Just make sure you have some extra heat pads on hand if you need to reheat it.

Can you dilute fake urine with water or mix it with real urine?

No this would be a bad idea, both of these would affect the chemical composition of the fake urine. Products such as QuickFix are a complete product and contain the same urine ingredients as is found in your body. Adding random elements to the liquid will result in you failing the test. You just need to take care to follow the instructions and make sure when submitting your sample it is warm enough and at the correct temp.
