I'm a pitcher, and I have done months of research about AS and it seems to me that Winstrol makes your existing muscles faster. Is this true? Also, I have read that Winny only cycles have given the users sore joints, etc. I cannot have that as a pitcher, since pitching is already very hard on the joints. What would be my best bet to get my fast twitch muscle fibers FASTER but remain injury free? Any advice would be greatly appreciatted....Thanks
