So I was talking to an ex bodybuilder at the gym (detached pec so he can't compete anymore) what he was telling me was 2 major things. 1st he said never to run test prop in a stack, as it binds to strongly to your receptors, obviously minimizing the effects of everything else in the stack. The 2nd thing was that you are not to run anything over 7 weeks because the receptors can only handle so much of the overload and once again minimizes the effects. I haven't been able to confirm or deny the theories. What are your opinions ?
