I don't really think it was rampant in the early stages of Baseball. Where there some guys who tried different things? Probably. However, if you actually look at the development of synthetics and PEDs in general, the science was not really there to help Baseball, like it did Football etc. I think pitchers have been using for years but not so much other positions and hitters. I think that's much more recent. Building bulk does not really help you in Baseball. I am skeptical of it's wide spread usage before the late 70s, early 80s. JMO.
