This might be a stupid question, but how come athletes don't verify that any medication, supplement, or drug that they are taking isn't or have ingredients that are on the banned list? And to do it before they actually take it. May be there's something more to it, but if I were a professional athlete and testing was being done in my sport, I would take every precaution to avoid triggering a positive test especially if I were a high profile and highly paid athlete. Wouldn't it be logical to find other treatments that wouldn't trigger a positive test?
I'm not saying he's guilty or not guilty, but isn't this common sense or am I missing something?
