I have a very serious question here I am hoping to get answered. I have recently been reading some old threads and it seems like today's big no no's were widely accepted as the way thing were done years ago. Example. Deca only cycle, is it true that this used to be considered ok to do? PCT Protocols constantly changing too. Along with Pyramid cycles that are now considered wrong. How do we know that current protocols viewed as acceptable won't become very wrong in a few years. How do we know what we are doing is right when so much changes in what is perceived as right and wrong.
