MGF (Mechano Growth Factor) is the muscle repair peptide your body produces after heavy training. Community users report faster recovery from localized post-workout injections, though the only rigorous human cell study found no proliferative effect. Its 5-7 minute half-life makes timing everything.

The 5 to 7 minute half-life changes everything about how you use this peptide. You can't bring it home from the gym. You inject within minutes of your last set, or you're wasting product. Reconstitution math for a 2 mg vial with 1 mL bacteriostatic water: each 0.05 mL (5 units on a U-100 insulin syringe) delivers 100 mcg. For 200 mcg, draw 10 units. For 300 mcg, draw 15 units. For a 5 mg vial with 1 mL BAC water: each 0.02 mL (2 units) delivers 100 mcg. Draw 4 units for 200 mcg, 6 units for 300 mcg. The non-obvious thing most beginners miss: subcutaneous abdominal injection defeats the entire mechanism. MGF is a paracrine signal. It needs to be near the muscle you just trained. SC abdominal delivery leads to systemic enzymatic degradation before any peptide reaches the target tissue. Also, split your dose bilaterally when training paired muscles. One hundred mcg per side for biceps, quads, or pecs. Keep protein intake at or above 1.8 g/kg per day. Satellite cells can't build anything without amino acid substrate.
