the only thing that can mess you up is if she is pregnant
Thats incorrect. Labs are not allowed perform such tests on urine samples collected for a drug test.
Even if a lab were to break the law and ran such a test, the lab would not report that the male donor is "pregnant". The lab would state that the male donor has prostate cancer or testicular cancer.
Just as HCG horomones are elevated in expectant mothers, they are also elevated in males with testicular cancer, or prostate cancer.

The "pregnant" story is nothing but a myth taken from an old Cheech & Chong comedy skit.

First Sub - Mixed some QF with clean human - Awaiting Results So I used my girlfriend's clean urine - the only issue is that she drank a bunch of water so she could be sure to go -- the sample looked almost completely clear... in a last minute fear of dilution I mixed about 30% QuickFix 5.7 and 70% her urine... total of about 3oz was given to e-SCREEN lab... Temp OK crotched with toe warmer on third pair of undies. I think I am GOOD TO GO (pre-employment) however the simple fact that I submitted part female part synthetic is making me paranoid Rating: 5
