Good post musclescience! See he took the time to type all that ip for u man, read that and then take a few months and really thing about this. I know ur 18 and think ur grown fully and all that but ur so far from being physically mature bro ur just starting to grow. I mean if ur a freak of nature and think u have a shot at being a pro bodybuoldr or athlete then u might have a good reason. If I could go back I would have never taken gear ever.. if ur anything like me u are probably gunna cycle anyway, if that's the case stay away from deca and tren forsure. Do ur research and respect the drug, steroids are a tool a bodybuilder has if ur diet and training are shit then gear will have very very little value to u.
