MGF
THE STEM CELL ACTIVATOR
Mechano Growth Factor; IGF-1Ec
MGF (Mechano Growth Factor) is a splice variant of IGF-1 that your body produces naturally after muscle damage from exercise. It's like a distress signal that activates dormant muscle stem cells (satellite cells) and tells them to start repairing and building new muscle tissue. Supplementing with MGF can accelerate this natural repair process.

Market evidence
MGF product testing and COAs
We found certificates from some of the MGF vendors we track. Based on the certificates our crawler found; vendors may publish more than we index. Research on this page describes the molecule. Vendor certificates concern particular market samples or batches; they do not change the research evidence or establish clinical safety, sterility, or suitability for use.
