PEG-MGF
Also known as PEGylated MGF, Mechano Growth Factor, IGF-1Ec
One-dose burn-down
Half-life
2.0 days
Tmax
6.0 h
Typical dose
200 mcg
A PEGylated splice variant of IGF-1 (mechano growth factor) used by researchers/athletes to extend the very short half-life of native MGF.
Mechanism of action
MGF is an IGF-1 splice variant that activates muscle satellite cells; PEGylation slows clearance to prolong exposure.
Research peptide — not approved and no rigorous human PK exists. Native MGF lasts minutes; the PEGylated half-life here is an estimate only.
