RebuildPEG-MGF
Mechano growth factor. Repair what training breaks down.
About
What it is
PEG-MGF is a PEGylated version of mechano growth factor — the growth factor your muscles produce in response to mechanical stress. The PEG modification extends its half-life, giving damaged muscle fibers more time to repair and grow.
How it works
PEG-MGF is mechano growth factor with a polyethylene glycol modification that extends its half-life. Natural MGF is released by muscle fibers after mechanical stress (training). PEG-MGF provides a sustained signal that activates satellite cells — the stem cells of muscle tissue — promoting repair and growth.
Benefits
Who it's for
What to expect
Week 1–2
Satellite cell activation increases. Post-workout recovery improves.
Week 4–6
Muscle repair accelerates. Soreness decreases between sessions.
Week 8–12
Enhanced muscle development with continued training.
Safety & tolerability
PEG-MGF works through your body's existing muscle repair pathways, just with a longer duration of action. The PEG modification is well-established in pharmaceutical science. Our care team reviews your training status and monitors your response.
How we compound
Single-source API
Every peptide is sourced from one vetted pharmaceutical-grade supplier — no blending from multiple sources.
Third-party tested
Independent labs verify purity, potency, sterility, and endotoxin levels before any batch is released.
Care team reviewed
A real person reviews your profile, your protocol, and your progress. Not an algorithm.
