No lawnsaver,I don't believe we will ever know the entire depth of things.The drugs themselves are relatively simple compared to the complexity of their reactions in the human body(as well as rodent/cattle bodies,lol).There are literally a million different responses that are taking place once anabolics interact with DNA from ALL different receptors on cells(which aren't limited to MUSCLE cells)and I believe science has only scratched the very tip of the surface,and we're all way behind these guys,lol...
