MGF benefits
From the PeptideBase research library. Educational only — not medical advice.
Studied effects
- muscle satellite cell activation following mechanical loading
- autocrine/paracrine local muscle repair signal (distinct from systemic IGF-1)
- progenitor cell proliferation and fusion enhancement in vitro
- PEG-MGF variant extends half-life for research applications — no human clinical data for either form
Mechanism
Splice variant of IGF-1; acts locally at site of muscle damage to activate satellite cells (muscle stem cells) for repair and hypertrophy
