10 Vials of 2mg, 5mg, or 10mg PEG-MGF – Lab-tested, high-purity pegylated research peptide. Supports muscle repair, satellite cell activation, and tissue regeneration studies with secure payment and fast, discreet shipping.
PEG-MGF (Pegylated Mechano Growth Factor) is a synthetic peptide derived from a splice variant of insulin-like growth factor-1 (IGF-1), specifically modified through PEGylation—the attachment of polyethylene glycol to extend its stability and half-life. While native MGF has a very short half-life (5–7 minutes), PEG-MGF lasts 48–72 hours, allowing prolonged biological activity.
It functions by activating muscle satellite cells (myogenic stem cells), promoting their proliferation and differentiation into new muscle fibers. This makes it a key peptide in muscle repair, regeneration, and hypertrophy following mechanical stress or injury. It also stimulates the MAPK/ERK signaling pathway, enhancing protein synthesis and tissue recovery.
