THE MUSCLE REGULATOR
Growth Differentiation Factor 8; MSTN
Myostatin (GDF-8) is your body's natural limiter on muscle growth. It tells muscles "that's enough" and prevents them from getting too large. Animals and rare humans born without myostatin develop extraordinary muscle mass. Myostatin inhibitors (not myostatin itself) are what people use to block this signal and unlock muscle growth.
