PEG-MGF is a PEGylated analogue of Mechano Growth Factor (MGF), which is the E-domain splice variant of IGF-1Ec. Native MGF is short-lived in circulation; PEGylation significantly extends its duration, enabling researchers to study regeneration, repair, and mechanotransduction pathways with improved stability. https://www.candygym.fitness/product/peg-mgf-4-mg-2/
