hey brandon. first of all i want to say thanks for all the info, you've been quite helpful for my cause.. i just had a couple quick questions..

1) what is the exact temperature cutoffs for pee... i heard it was 96-98 degrees but i can't be sure. is this true?

2) if i have a friend urinate for me the evening before the test, do i have to freeze it right away or something?

also, i get randomly drug tested at school so until i'm clean i plan on using the substitution method in case i get tested. the only thing i have to worry about is whether or not the age of the urine can be detected, and the exact temperature i need to keep it at.

any help would be appreciated, thanks a ton
