PCT in my opinion is something created on internet , but if you stop and think with your head you will understand when you start gear if you stop you will lose because you are putting exogenous stuff in your body on dosages that your body never will produce to keep the gains. Even when you got bigger like 100kg shredded you will need maybe 1gr test just to keep this muscle mass .
That´s why i always said to any natural guy : Think very well before you start , are you life from fitness image? are you be competition athlete? or you have a dream to get huge? If you want it badly understand this is a street without turning back .

Doing PCT you are using drugs the same way : clomid, tamox, HCG , toxic for liver as the steroids used to grow , that´s why i try to avoid AI ( only when needed ) because the more drugs you use more stress you cause to your body . PCT is always a step back losing all or almost all and start again . When we start using gear the goal is always improve every day and the only way is stay on always , of course doing some cruises to rest the body but never off
