MGF (Mechano Growth Factor) Peptide

MGF is the C-terminal splice variant of IGF-1 (also called IGF-1Ec) that is upregulated in muscle tissue following mechanical overload or damage. Unlike systemic IGF-1, MGF remains locally active, with preclinical studies indicating roles in satellite cell recruitment, myoblast proliferation, and differentiation timing in mechanically stimulated tissue. First characterized in research by Goldspink’s group, it is widely used in mechano-transduction and muscle biology studies. This research-grade lyophilized peptide is synthesized under strict quality controls and provided with full analytical documentation for use in laboratory research settings only.
