Dosage Protocols

FormDoseRouteFrequency
Standard MGF200–400 mcgIM (target muscle)Post-workout
PEG-MGF200–400 mcgSC2–3× per week

Standard MGF has a very short half-life (~minutes) and is injected intramuscularly into the target muscle immediately post-workout for local action.

Reconstitution

Reconstitute lyophilized MGF with bacteriostatic water. Use the peptide calculator for volumes. Standard MGF is highly unstable once reconstituted — use immediately or within hours. PEG-MGF is more stable and can be stored reconstituted.

Timing & Cycles

Standard MGF: inject bilaterally into target muscles immediately post-workout (within minutes). PEG-MGF: inject subcutaneously on training days or 2–3 times per week. Typical cycles run 4–6 weeks.

Storage

  • Lyophilized: -20°C long-term, 2–8°C short-term
  • Reconstituted standard MGF: use immediately — extremely unstable
  • Reconstituted PEG-MGF: refrigerate, use within 14–21 days
