I concur about the clean food, esp at your age. By your age I was around 240, but with no muscle tone. Good clean food is the best Anabolic out there. Supplements are used to supplement your diet, not replace missing elements (except whey protein) Keep the protein high, I cannot stress enough how important it is to have at least one gram of protein per pound of Bodyweight!!! It makes all the difference as you look and feel fuller, and your muscles are getting the right building blocks. Also what is your workout volume like, are you only benching and doing arms? If so cut that ISH out and do some SQUATS dig deep and dirty Squats. Squats, the right diet, and the right mental attitude is what builds champions.
