I don't know what thread you read but frozen urine is good for about a year, refrigerated urine is good for about 2 weeks, and urine at room temp is good for a little over 8 hours. Don't use glass. It may break.
FakeBoobsRule Reviewed by FakeBoobsRule on . a clever idea to pass... im pretty sure im clean as of right now.. and will have my piss test in a few days time. i was wondering if this would work for any future tests. piss in a jar and freeze it, then a day or 2 before my next test, i let it thaw and keep it close to my body for a few hours to heat it up. a) would they be able to tell it was frozen b) how long would piss stay fresh frozen thanks :) Rating: 5
