inject piss in your bladder? how about during the olympics, the females use prefilled balloons or condoms of clean piss, up in their pussy, then pop it when they take the test. you remember Flo JO? the fastest female sprinter?
anyways, everyone says try goldenseal, or try "quick caps" its like a pack of herbal stuff you take 4 hrs before you test. get it at GNC, you have to ask for it, its behind the counter. i've tried, passed my test. i have a friend take it twice, because his piss came out "too watery", there wasnt enough trace of actual piss, just water. the stuff works. but they didnt hire him because the test was inconclusive.
