I am 15 years old (about to turn 16) and about 150 pounds. I have been lifting seriously and eating seriously for about 3 months. I started out at about 145 pounds when i started seriously lifting. Yeah I look a little bigger and little more filled out and stronger. But i really want to make some serious gains. I take N.O. Xplode and muscle, take in about 2200-2500 calories and 160 grams of protein daily. For the past month I have pretty much leveled off at the same size and weight but im getting stronger. Should i be taking different or more supplements? More calories or protein? More time? or just letting my body fill out as i grow?
