PEG-MGF

Pegylated Mechano Growth Factor — Modified IGF-1 for Muscle Repair

What It Is

PEG-MGF (Pegylated Mechano Growth Factor) is a pegylated variant of the MGF splice of IGF-1. The PEG modification extends its half-life, allowing systemic distribution for muscle damage repair and satellite cell activation. It is considered an experimental growth factor peptide.

Mechanism of Action

Activates muscle satellite (stem) cells at sites of mechanical damage, promoting muscle fiber repair and new cell fusion. The pegylation extends circulating half-life compared to native MGF, enabling systemic rather than purely local effects.

Benefits

Muscle repair acceleration
Satellite cell activation
Extended half-life (PEG)
Post-training recovery
Muscle fiber regeneration
