If you are worried, you could always get an adulteration hometest to make sure it is still good.

I don't remember reading anything about freezing and thawing and freezing again ruining urine.
suzieque Reviewed by suzieque on . Question about Freezing and defrosting urine Okay, I have been subbing with a friends voids for a while now. To get to the point, I am wondering if the urine changes properties as it freezes and is defrosted??? If I defrosted 2ozs. and refroze within 2 hours is that urine still good to use? It was exposed to room temp. for about 2 hours (at most). Thank you for any help and knowledgeable answers Rating: 5
