MGF (Mechano Growth Factor)
MGF (Mechano Growth Factor) is a natural variant of the IGF-1 gene that the body produces in response to muscle being stretched or loaded during exercise. Research focuses on muscle repair, activation of muscle stem cells, and recovery from exercise-related damage.

Overview of MGF (Mechano Growth Factor)
Activates satellite cells and promotes muscle repair through a unique E-domain peptide that is released during mechanical strain, working independently of the mature IGF-1 signaling pathway.
The unique C-terminal E-domain peptide activates muscle satellite (stem) cells, initiating the repair response to exercise-induced or traumatic muscle damage.
Acts as a local autocrine/paracrine signal at the site of mechanical strain, unlike circulating systemic IGF-1.
Increases myoblast proliferation without premature differentiation (proposed), expanding the progenitor pool available for repair.
The E-domain peptide may signal through receptors distinct from IGF-1R (proposed), suggesting an independent mechanism from mature IGF-1.
Rapidly expressed after resistance exercise, peaking before the delayed splicing of IGF-1Ea (the systemic form).
Synthetic PEG-MGF has extended half-life to improve stability, as native MGF is rapidly degraded in circulation
