i am running 500mg a week and have had great results but i still havent reached my goals. i saw somewhere someone said "if u can recover from a 12 week cycle u can recover from a 15" part of me believed it cuz its what i want to hear but i want everyones opinion. If a 15 week cycle is just as dangerous as a 12 week cycle is it worth it?? because i know at some point homeostasis comes in to play and i dont have much knowledge on that subject.
