Overview
About PEG-MGF
Mechanism of action
PEGylated analogue of mechano growth factor (MGF, splice variant of IGF-1); activates satellite cells for muscle repair; promotes myoblast proliferation; PEGylation extends half-life dramatically.
Safety profile
Hypoglycemia risk, water retention, potential insulin resistance, injection site reactions. Similar IGF-1 axis risks. · PEGylated MGF; extended half-life; limited data; no proven major harms; sourcing quality main concern

Studies & key findings
- PEGylation of the MGF E-domain peptide extends its half-life by creating a hydrophilic polymer shield that reduces renal clearance and protease degradation, converting a peptide that degrades in minutes into one with a half-life measured in hours — enabling systemic rather than purely local delivery.
- A sheep model of myocardial infarction found that intravenous administration of the MGF E-domain reduced the area of compromised cardiac muscle by 35% compared to controls and preserved systolic function, suggesting that when delivered systemically at sufficient concentrations the peptide reaches ischemic tissue and is cardioprotective.
