been a while since i've done a cycle, and back when i used to do them it seemed more common to do one kind of gear for about 6 weeks, then switch to totally different compounds for the next 6 weeks. the reasoning was that it was supposed to help prevent receptor downgrade that comes from using the same thing for a long period of time. why is it those kind of cycles have seem to died and everyone seems to stay on the same stuff the whole way through the cycle?
