I do PCT everytime for every cycle...yes back in the "day" they didnt know about PCT but im pretty sure they would have appreciated it. There are numerous reasons that PCT or the "idea" of PCT was developed through countless studies and alot of blood work screenings. Point blank PCT works and should be done in every cycle...you say your body is not affected by not doing PCT...do you run bloodwork after your cycle is done? if not..then how do you "really" now?
