Also known as: Pegylated Mechano Growth Factor, IGF-1Ec E-peptide PEGylated
PEG-MGF is the PEGylated 24-amino-acid C-terminal E-domain of the IGF-1Ec splice variant. Native MGF E-peptide has an estimated half-life of 5–7 minutes; PEGylation extends this to approximately 24 hours by reducing renal filtration and proteolytic degradation. No human pharmacokinetic study has been published. The compound activates muscle satellite cells via a receptor distinct from IGF-1R, promoting proliferation and repair in mechanically loaded or damaged skeletal muscle — complementary to the IGF-1R anabolic pathway. WADA-prohibited under S2 (growth factors).
