Understanding MGF The Mechano Growth Factor Peptide.pdf

Mechano Growth Factor (MGF) is a splice variant of Insulin-like Growth Factor 1 (IGF-1), specifically expressed in response to mechanical stress or muscle damage. Discovered in the late 1990s, MGF plays a key role in muscle repair and growth, making it a topic of interest in sports science, bodybuilding, and regenerative medicine. Unlike its parent compound IGF-1, MGF is produced locally in muscle tissue, offering targeted benefits for recovery and hypertrophy.
