Need help with drug test!!!

[BostonScott6911]

I have a random drug test at work coming up any day now and I smoke marijuana as well as take Subutex daily (my work doesn't know) I plan on bringing clean pee in with me everyday but my question is how long can I keep a bottle of someone else's urine before it is no longer good to use on the drug test? Will they be able to tell it is old and also can they distinguish between male and female urine? Also what temperature are they looking for when they collect the sample and I am using the handwarmer and condom or aspirin bottle rubber banded to my leg method so if anyone has a better suggestion please let me know....I am not going to be watched as I pee just so you guys know
