What's considered "fast acting"? The guy had it from Friday afternoon to Monday afternoon. Then it probably doesn't get to the lab unti Tuesday and I'm guessing they don't test it the same day they get it. Is 4 or 5 days considered "fast acting"? Its fast acting in the nature that it doesnt stay in your system long. Heres Conte's prior comment on it Were you surprised that Ryan Braun tested positive?: "No, I was not surprised. In fact, three weeks before that, I was in Vietnam and I was interviewed by somebody from the New York Daily News. It was when the growth hormone testing was being introduced. And I don't think growth hormone is effective as a performance enhancer. At that time, I basically said that what they're doing is using fast-acting testosterone - creams, gels, orals, patches - and they clear so quickly, sometimes in a matter of hours. … They could conceivably, after a game, use testosterone to help with tissue repair and healing and recovery and by the time they'd show up at the park the next day, their PE (progesterone/estradiol) ratio would be normal. I always knew there was this giant loophole that you could drive a Mack truck through." Also, I would guess if a player took a PED one day and peed in a cup the next day it would show up. Isn't "fast acting" really referring to the affects on the person taking the PED not how quickly it enters his system (which I think would be almost immediate). If you inject somthing directly into a sample of urine, I would assume it would show in test.
