PEG-MGF (PEGylated Mechano Growth Factor)
A polyethylene glycol-modified version of MGF with dramatically extended half-life. Provides systemic rather than purely local satellite cell activation for broader muscle recovery.
How it works
PEGylation protects MGF from rapid degradation, extending half-life from minutes to hours. Activates satellite cells systemically for whole-body muscle recovery.
Key facts
- Molecular weight: ~5000 Da (with PEG)
- Half-life: ~30 minutes to several hours (vs 5-7 min native)
- Bioavailability: ~85% subcutaneous
- Storage: Lyophilized: -20°C. Reconstituted: 2-8°C for up to 48 hours.
Dosing overview
- Typical dose: 100-200 mcg
- Frequency: 2-3x per week
- Duration: 4-6 weeks
- Route: Subcutaneous injection
Reported benefits
- Extended half-life vs native MGF
- Systemic satellite cell activation
- Whole-body recovery
- Less frequent dosing
Possible side effects
- Injection site reaction
- Mild joint ache
- Fatigue during adaptation
Research
- PEGylated MGF pharmacokinetics (2019): PEGylation extended bioactive half-life from 5 min to 30+ min with preserved satellite cell activation.
- Systemic vs local MGF delivery (2020): Subcutaneous PEG-MGF produced systemic muscle recovery benefits across multiple muscle groups.
