MGF (Mechano Growth Factor) is a splice variant of insulin-like growth factor-1 (IGF-1). Research reveals it to have positive effects on tissue growth, wound healing, cardiac repair, and skeletal muscle repair. 

There is good evidence to indicate that MGF improves muscle repair following injury and boosts recovery times following exercise or injury.

 MGF may even protect vulnerable tissue against mechanical stresses such occurs during running, weight training, and repetitive motion.
