turn on, turn off, question mark

Fake pee has a limited life. Most synthetic urine has a shelf life for up to 2years.

Always check for a brands’ shelf life while purchasing it since this varies with different products. The better the brand, the longer the shelf life.

After the said shelf life, the product will, unfortunately, be not in a position to pass a test.

The components of the sample will break down, and the effectiveness of the product will automatically reduce.

In case of such a case, dispose of the product and buy a new brand. Avoid making a mistake of using expired urine, since you will not be doing yourself any good.

It’s better to spend an extra penny than acting cheap-stake and deciding to use a croaked product.

How to properly store fake pee

As mentioned earlier, fake pee can as well go bad before its shelf life. How you store your product will determine how long it will last.

On the products’ manual, it’s always listed that you store it in a cool temperature away from direct sunlight.

Remarkably, you may opt to freeze the product. Here, this is ideal for some products, especially those in premixed form, since the properties like the fake pee’s pH level will not be disrupted.

It is applicable whenever the use of the product will be at a future date. On the contrary, if you will be using the pee in a few days, freezing is not the option.

Store it in a well-sterilized place, away from the pollutants. Have it properly sealed to avoid the air from reacting with the product, which may cause oxidation of the urine sample.

Conditions synthetic urine may go bad.

There are certain states which may terminate the shelf life of a synthetic urine.

Direct sunlight exposure

Direct sunlight will break down the product’s elements, thereby contaminating the product and reducing the efficacy level.

This is a red flag sign that results will come out positive or get caught up using fake pee. You can now imagine what would occur from submitting a contaminated fake pee for lab urinalysis.

Sadly you may end up losing your job position or end up in jail. All this is avoidable with proper storage and care.

Therefore, store it in a dark, cool place away from direct sunlight.

Freezing the fake urine

Freezing of fake urine is always necessary if you need to use the product at a future date, (before the expiry date). Here, you will not have escaped from the fact that it can still expire even while frozen.

Do it and mark the indicated expiry date to avoid disappointments.

Yes go ahead and freeze it, but avoid constant defrost and reheating. Such incidence will reduce the amount of water in the synthetic urine, affecting the concentration rate. Avoid test fails from such mistakes.

Even with the freezing option, i would not really recommend the process.

Not all fake pee kits require freezing like the sub solution urine, no freezing is needed since it is in powdered form. It is 100% effective with a long shelf life that will maintain the effectiveness of the product for long.

Heating synthetic urine

Synthetic urine authenticates that heating will not affect the product. We agree, but what about regular heating? Once you heat it, let it cool to the required temperatures (90-100F).

If you use a heating pad, this is easy to have it at the right temperature. For microwave users, you need to be careful with how you do the heating.

If it’s possible, have it heated whenever the need to carry out the drug test arises.

Reheating it several times will drain the amount of water in the urine and eventually disrupt the potency of the sample.

Besides, reheating it will reduce the volume of the brand. Heat it only when the need arises, you will avoid compromising everything.

Signs synthetic urine is void for use.

Colour change

Suppose the synthetic urine has changed the colour from yellowish to any other colour, that one sign that it has gone bad.

It happens with a loosened sealing. The oxygen will oxidize the product, hence contaminating it.

Have proper sealing to have it last long and improve its sterilization. In case it goes bad, then you will realize some bacteria growths.

At times, It may have changed from the normal colour to cloudy, these fungi infections.


Synthetic urine should smell just like real urine. Therefore, if you realize a unique smell with the fake pee that hint that the product has spoiled.

In case of an abnormal smell, do away with it for your own good. At times, it may appear thicker to the normal look.

This also will tell you that the product is off its usage. Smell and appearance will guide you on how to detect a congealed pee.


Can one mix two fake urine to make one sample?

There are different reasons you may decide to mix two different synthetic urine and come up with one sample.

Yes, this is possible, but with precautions. Reasons most people prefer mixing are that you may have purchased a new brand, but the previous one was not fully used, having different kinds of quality or trying to improve one of the product’s efficiency.

Perhaps you may pass a test, but did you mix that right? The quality of the brand always matters, so if you decide to mix different qualities, you may eventually compromise the product.

Again, if you decide to mix, you cannot do that with an expired product thinking it will work. Always dispose of bad product.

If there is no valid reason to mix two products, avoid the process to maintain one product’s accuracy.
