I have looked at formulas at GNC, but I have no idea which one is the most effective for building muscle mass. If you can cite studies that would be awesome. Please don't just tell me that creatine doesn't work, if you believe that then please cite a study saying that. Otherwise I am a 5'8'' 16 year old, I weigh 165 pounds, and I am trying to build muscle mass. Also if you know the dosages and how to start out taking it (cycles, stacking, etc) that would be great.
