Can Synthetic Urine Be Reheated For Drug Test?

Can synthetic urine be reheated for drug tests?

Yes, you can reheat Quick Fix multiple times as needed without any problems. But that is only possible if you have not used the product.

If, for any reason, your drug test doesn’t take place, store it in its packaging or box for future use.

There’s no reason to buy Quick Fix again when you have unused bottles with you.

Quick Fix is unique since it has a shelf life of at least 18 months after the date of production.

Reheating synthetic urine several times will not affect its ingredients. You can even reheat it every day for a whole year and still works best.
