MGF

Mechano Growth Factor

MGF (Mechano Growth Factor) is a splice variant of IGF-1 that is expressed in muscle tissue in response to mechanical stress (exercise) and damage. It plays a role in activating satellite cells, which are muscle stem cells critical for repair and hypertrophy. The synthetic version (PEG-MGF) includes polyethylene glycol modification for extended half-life.
Reported Benefits

Potential Benefits

  • Research suggests activation of muscle satellite cells for repair and growth
  • May support localized muscle recovery after exercise-induced damage
  • Preclinical data indicates potential for muscle tissue repair
  • PEGylated form provides extended activity compared to native MGF
  • Studies suggest it may promote muscle stem cell proliferation without full differentiation (priming for repair)
Research Dosing

Recommended Starting Dose

PEG-MGF: 200 mcg intramuscularly or subcutaneously (experimental)

Based on published research protocols. Not a prescription.

Dosing Protocol

PEG-MGF: 200 mcg injected 2-3 times per week, often into or near the target muscle group. Non-PEGylated MGF has a very short half-life (minutes) and requires bilateral injection. Cycles of 4-6 weeks are typical in anecdotal protocols. Often used alongside other growth hormone secretagogues.

Research Timeline

Expected Timeline

Phase 1

Anecdotal reports describe improved recovery and muscle soreness reduction within 1-2 weeks. Measurable muscle adaptation would require longer periods.
