im about to start my first cycle ever with sustanon 250. ive never did this before and would like some advice. the reason im going with this is its the only one i can find right now because a buddy of mine is using it. so the questions i have are what size needle do i use, how much, how long of a cycle on and off, were to inject and what pct do i go with. to give some stats of my build now im 6ft 210lb and never really did much working out. any help?
