I question your cred wrote:
Why do you think Blake in particular needs steroids as well as this stuff to be good, as opposed to a guy like Gatlin?
Me, I believe steroid effects last, and that Blake has taken enough for a lifetime, that guy is dense with muscle fibers. If he can take your IGF stuff freely as you suggest everybody does, then why does he suck so badly this year? Do you think he is off the IGF, and if so, why would he be, when you suggest that it can be done freely?
Can you do a small amount of research before you post; I have seen body builders lose mass and strenght with in few months off of PEDs. There is absolutely nothings you can put in the human body that last forever.
