THE MUSCLE UNLEASHED
ActRIIB-Fc, Soluble Activin Type IIB Receptor Fusion Protein
ACE-031 works by trapping myostatin, your body's natural brake on muscle growth. By neutralizing this signal, your muscles can grow more freely. Originally developed for muscle-wasting diseases, it's now studied for its ability to increase lean mass, strength, and even bone density without the side effects of steroids.
