PEG MGF (2 mg Vial) Dosage Protocol
PEG MGF Dosage Chart
PEG MGF is dosed at 200 mcg–500 mcg daily via subcutaneous injection in educational protocols. A 2 mg vial reconstituted with bacteriostatic water yields about 0.667 mg/mL. This information is for research and educational use only.
Reconstitute: Add 3.0 mL bacteriostatic water (max vial capacity) → ~0.667 mg/mL concentration.
Typical daily range: 200–500 mcg once daily (gradual titration over 8 weeks).
Easy measuring: At 0.667 mg/mL, 1 unit = 0.01 mL ≈ 6.67 mcg on a U-100 insulin syringe.
Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F); avoid freeze–thaw cycles.
PEG MGF is a pegylated variant of mechano-growth factor, a muscle-derived IGF-1 splice isoform that is upregulated after mechanical stress or injury[2]. The unique C-terminal E peptide of MGF activates muscle satellite cells and local protein synthesis, initiating tissue repair and growth in addition to IGF-1 receptor signaling[3]. This educational protocol presents a once-daily subcutaneous approach using a practical dilution for clear insulin-syringe measurements.

Standard / Gradual Approach (3 mL = ~0.667 mg/mL)
Weeks 1–2
200 mcg
30 units (0.30 mL)
Weeks 3–4
300 mcg
45 units (0.45 mL)
Weeks 5–6
400 mcg
60 units (0.60 mL)
Weeks 7–8
500 mcg
75 units (0.75 mL)
Frequency: Inject once daily subcutaneously. Pegylation extends MGF’s half-life, allowing systemic once-daily SC dosing instead of frequent intramuscular injections[7]. This schedule uses the largest practical dilution (3.0 mL) to keep per-injection volumes easy to measure accurately on standard insulin syringes.
Reconstitution Steps
Draw 3.0 mL bacteriostatic water with a sterile syringe.
Inject slowly down the vial wall; avoid foaming.
Gently swirl/roll until dissolved (do not shake).
Label and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.
Supplies Needed
Plan based on an 8–16 week daily protocol with gradual titration.
Peptide Vials (PEG MGF, 2 mg each):
8 weeks ≈ 10 vials
12 weeks ≈ 17 vials
16 weeks ≈ 24 vials
Insulin Syringes (U-100):
Per week: 7 syringes (1/day)
8 weeks: 56 syringes
12 weeks: 84 syringes
16 weeks: 112 syringes
Bacteriostatic Water (10 mL bottles): Use ~3.0 mL per vial for reconstitution.
8 weeks (10 vials): 30 mL → 3 × 10 mL bottles
12 weeks (17 vials): 51 mL → 6 × 10 mL bottles
16 weeks (24 vials): 72 mL → 8 × 10 mL bottles
Alcohol Swabs: One for the vial stopper + one for the injection site each day.
Per week: 14 swabs (2/day)
8 weeks: 112 swabs → recommend 2 × 100-count boxes
12 weeks: 168 swabs → recommend 2 × 100-count boxes
16 weeks: 224 swabs → recommend 3 × 100-count boxes
