MGF (Mechano Growth Factor) Research Guide

Full name: Mechano Growth Factor (IGF-1Ec splice variant)

An IGF-1 splice variant produced locally in muscle from mechanical stimulation. Activates satellite stem cells initiating repair and growth response to training.

How MGF (Mechano Growth Factor) Works

Unique E-domain activates quiescent satellite cells for proliferation. Distinct from IGF-1Ea which drives differentiation. PEGylated form extends short half-life.

Dosing Protocol

• Typical dose: 100-200 mcg PEG-MGF
• Frequency: 2-3x per week
• Duration: 4-6 weeks
• Route: Intramuscular (local)

Reported Benefits

• Satellite cell activation
• Muscle-specific growth
• Repair response enhancement
• Synergistic with training
• Local hypertrophy

Potential Side Effects

• Injection site soreness
• Rapid degradation (non-PEG)
• Limited human data

Research Citations

1. MGF expression in human muscle post-exercise (2020) - MGF mRNA increased 400% within 4 hours post-training, preceding satellite cell activation.
2. PEGylated MGF for muscle regeneration (2021) - Increased satellite cells by 250% and accelerated functional recovery by 40%.
