MGF

Mechano Growth Factor (MGF) originates from the IGF-1 gene, produced in response to mechanical stress such as exercise. This peptide is a variant of Insulin-like Growth Factor 1 (IGF-1) that plays a role in muscle repair and regeneration. It functions by stimulating the proliferation and differentiation of satellite cells, aiding in muscle recovery. Research on MGF began with investigations into its effects on muscle hypertrophy and adaptation to physical stress. Today, it is primarily studied for its effects on:

• Muscle regeneration
• Cell proliferation
• Exercise adaptation
• Tissue repair
