pct is post cycle therapy, it is what you do to help restore your natural testosterone levels that were suppressed while on cycle. it is very important, anyone who says different is uneducated on the subject. we have an entire section dedicated to pct, head over there and read all the posts at the top, then read them again. also be careful about the way you phrase things, ''source fishing'' is referring to compounds you want but can't find, and that is against the rules.
