I'm not a fan of gear to begin with, but we won't argue about that...to each his own. However, I'd never recommend it to anyone who doesn't at least have a few years of experience in the sport. At your age, your natural test is raging. I'd at least wait until you get as much natural growth as possible and you really start to plateau. I appologize if it sounds like an attack. I'm just saying that at your age, you have a lot of natural potential. Please don't take it the wrong way.
Oh, one other thing...at least 1.5 grams of protein per lb of bodyweight when bulking. Good luck.
