MGF
MGF
MGF is the form of IGF-1 your muscles make after a hard workout — it's the localized "repair this fiber" signal. Used in research on muscle growth and exercise adaptation.
How MGF Works
A deeper look for the curious
For readers who want the full mechanism — feel free to skim.
MGF is the form of IGF-1 your muscles actually produce after a hard workout to trigger local repair. It activates "satellite cells" — the stem cells of muscle — which fuse into damaged fibers and rebuild them stronger.
