Follistatin is a naturally occurring glycoprotein that binds and inhibits myostatin, a negative regulator of muscle growth. Studied for muscle wasting conditions and performance enhancement. Gene therapy approaches also in development.

MGF (Mechano Growth Factor) is a splice variant of the IGF-1 gene produced in response to mechanical loading of muscle tissue. Also known as IGF-1Ec in humans. Research focuses on muscle repair, satellite cell activation, and recovery from exercise-induced damage.
