PEG-MGF extends the muscle repair signal MGF from a 5-minute half-life to an estimated 48 to 72 hours. Community users report faster recovery and reduced soreness within weeks. All published research tested native MGF, not the PEGylated form. Research peptide only.
150mcg · 2x/week
Summary: Add 1mL BAC water to your 2mg vial. Draw to 7.5 units on a U-100 syringe for a 150mcg dose. This vial will last 13 doses.

Reconstitution math for a 2 mg vial with 1 mL bacteriostatic water: total volume is 100 units on an insulin syringe, each unit delivers 20 mcg. So 150 mcg is 7.5 units, 200 mcg is 10 units, 400 mcg is 20 units. For a 5 mg vial with 1 mL bacteriostatic water: each unit delivers 50 mcg. That puts 150 mcg at 3 units, 200 mcg at 4 units, 400 mcg at 8 units. Start at the beginner dose (150 mcg, 2 times per week) even if you've used other peptides before. PEG-MGF has zero human dose-response data; the community arrived at these numbers by trial and error over years, not from clinical guidance. Inject post-workout, within 30 minutes of finishing your session. The satellite cell activation window overlaps with the mechanical damage signal your muscles are already producing. For bilateral muscle groups (quads, pecs), split the dose between both sides. A single-site injection for bilateral training misses half the target tissue. Don't combine PEG-MGF and IGF-1 LR3 in the same injection window. Stagger them by at least 4 to 6 hours. Both compete for satellite cell receptor binding, and concurrent dosing may negate the proliferation phase. Store reconstituted vials at 2 to 8 degrees Celsius. Use within 3 to 4 weeks. Discard if the solution turns cloudy or contains visible particles.
