MGF (Mechano Growth Factor) peptide molecular structure diagram from PubChem

Mechano Growth Factor (MGF) is a splice variant of IGF-1 that is expressed in response to mechanical overload of muscle tissue. It plays a role in muscle repair and hypertrophy by activating satellite cells, the muscle stem cells responsible for post-exercise muscle growth and repair.
