Myostatin is a substance your body produces specifically to inhibit muscle growth—an evolutionary mechanism to conserve energy by capping how much muscle you can build. The good news: leucine, HMB, and creatine monohydrate all block myostatin's inhibitory effects, which is part of why they work. Gaining muscle is literally overcoming your biology's resistance to it.
