I have a urine test in two days and i need to pass, no one will be watching me take a piss so its good, i got my mates urine who is clean but thing is how do i keep the temperature normal? i was told to get a condom and have it pissed it then tie it or tape it sealed shut and keep it in your undies near your balls and it would work? is this true? does any condom work or does it have to be no lube in it? also i need to ask why a condom is it about its sterilizied? apparently the urine cups are? and another thing my mate is going to piss around an hour before the test for me and ill keep it at normal temp woould it work?
