Overview
PEG-MGF is MGF with a polyethylene glycol (PEG) chain attached to slow clearance — hours of activity instead of minutes. Same satellite-cell mechanism as MGF, but you dose it less often.
Preparation
Recon: 2 mg vial + 3 mL BAC (0.67 mg/mL).
Protocol
| Period | Dose | Units (@ 0.67 mg/mL) | Frequency |
|---|---|---|---|
| Weeks 1–2 | 200 mcg | 30 units (0.30 mL) | 1x/day |
| Weeks 3–4 | 300 mcg | 45 units (0.45 mL) | 1x/day |
| Weeks 5–6 | 400 mcg | 60 units (0.60 mL) | 1x/day |
| Weeks 7–8 | 500 mcg | 75 units (0.75 mL) | 1x/day |
Cycle
4–8 week cycles. Post-workout dosing into the trained muscle. The PEG modification makes it more forgiving on timing than plain MGF.
