Kelly, I waisted a lot of money on supplements when I was young. I tried everything, but my metabolism was in overdrive well in to my 20's. I couldn't put on a pound and I was fortunate enough to have the Army bodybuilding champ in our supply room. He tried to help, but we are all different and some of us are not meant to be huge... We are just trying to tell you to save your money, look at your diet first, get that healthy and balanced and once you stop growing then give the supplements a shot...
