Gender does not matter in a drug test, despite what the anti-drug, pro-drug test, fear mongering propagandists try to program into the minds of the uninformed. The truth is, drug testing devices have no ability at all to determine if the sample came from a male or female. The devices can only detect the presence of drug metabolites. Only a genetic test can tell where the sample came from. And unless you are a criminal tangled up within the legal system (which nearly all rights are virtually relinquished), it is prohibited by law for labs to perform genetic tests without the donors written consent. They can only test the temperature, ph, creatinine, specific gravity, and look for drug metabolites.

With that being said, any human sample can be used for a sub as long as its drug free.

Horror stories of the Quick Fix?! Where did you read these at? The only time a person can fail with synthetic urine is if they used an expired batch with all of the urine components (creatinine, sg, ph, etc) broken down, or if they did not get the temperature right.

I've used the QF successfully since 2001 and passed my last UA with it in June of this year. I also home test my QF batches (using the Urinecheck 7 adulteration test strip) to make sure that all of the urine components will pass before going to the clinic. :thumbsup:
