Yes, urine grows bacteria after a few hours, so you'll need a different sample to use.

Also, that's definitely not sanitary in any way. Throw it out as soon as you can, dude.

Home test: yes. They can tell in a lab test if its more than like 12 hours old.

Yes they can tell if its old or not but not all labs conduct the age test.

Though they could probably tell if it was old urine, it wouldn't be because it had bacteria growing in it. Urine is essentially toned down ammonia and is pretty good at killing shit.

there's a thing on the home test that can tell if the sample is expired or not.

next time at least try refrigerating it, or get a donor on the same day.

nah, man, that's not a good idea, haha.

they can do tests on your piss to determine when it left your body (it has something to do with the bacteria level in it). that's one of the reasons why they have to do the testing on it within two days of it leaving your body (i'm almost positive it's two days, but don't quote me on that, haha).

keep tokin', man. :smoke:

EDIT: a good idea would be to have someone you know that doesn't toke up piss in a pill bottle (or something of that sort) the same day for you. by the time they do the tests on the piss, it's gotten to room temperature anyway, so they wouldn't be able to tell. and they DON'T do DNA tests, so it's safe to have someone else piss for you.

Do it American Beauty style (it works):
1) Get clean pee
2) Freeze clean pee
3) Let clean pee defrost before test
4) Let clean pee rise to body temp before test

If you leave piss around (room temp) it wont be usable.
