- PEG-MGF is MGF with a chemical 'time-release coating.' Where MGF is gone in minutes, PEG-MGF lingers for days — making systemic dosing practical in research.
What is it?
PEG-MGF is a pegylated form of Mechano Growth Factor (MGF, the IGF-1Ec splice variant). Polyethylene glycol attachment dramatically extends the very short half-life of native MGF.
In plain English
PEG-MGF is MGF with a chemical 'time-release coating.' Where MGF is gone in minutes, PEG-MGF lingers for days — making systemic dosing practical in research.
How it works
PEG-MGF retains the satellite-cell-activating activity of native MGF but with greatly extended plasma half-life due to PEGylation, enabling weekly or twice-weekly research dosing.
What researchers study
- •Satellite cell activation
- •Systemic muscle repair research
- •Comparison with native MGF and IGF-1 LR3
- •Cardiac and skeletal muscle studies
