PEG-MGF (also known as Mechano Growth Factor, PEGylated MGF) is a PEGylated splice variant of IGF-1 studied for muscle repair. This page covers what the published research does — and does not — establish about it in relation to muscle growth and recovery.
PEG-MGF is researched for Muscle repair, Recovery — which is why it appears in discussions of muscle growth and recovery.
Research status: Preclinical research.
How PEG-MGF is thought to work
PEG-MGF is a PEGylated form of mechano growth factor, a splice variant of IGF-1 that muscle produces after mechanical stress. PEGylation extends its half-life, and it is studied for activating satellite cells involved in muscle repair.
What it does not establish
Human data is limited. Affects growth-factor pathways.
Nothing on this page is a recommendation to use PEG-MGF, and Selpho publishes no dosing, reconstitution or sourcing information. Read how we decide what goes in the library.

Frequently asked questions
Preclinical research. Research relevant to this area covers muscle repair, recovery. That is a description of where the research points, not evidence that it will work for you — and Selpho does not provide dosing or medical advice.

Muscle repair and satellite-cell activation. Evidence is preclinical.
It means a polyethylene-glycol chain is attached to slow breakdown and extend how long the peptide stays active.
