Aight Question, I know that if you take enough niacin it will clear out your urine of drugs such as weed and some others, but would it work the same for a steriod? If so would 50 mgs a day be enough or would it take much more.

Reason I ask is because I am looking into promagnon 25 to get strenth up, and as a football player I can be drug tested although its never happened before. Also how long might a substance like this stay in system for a pee test.

Sorry if i posted this in the wrong section seemed right
