Mechano Growth Factor (MGF) is a variant of the Insulin-like Growth Factor 1 (IGF-1) that plays a crucial role in muscle repair and growth. It is produced in response to mechanical stress, such as exercise or injury, and helps stimulate muscle cell proliferation and differentiation. MGF is particularly important for recovery after intense physical activity. This growth factor is primarily expressed in skeletal muscle and is involved in the regeneration of muscle fibers. By promoting the repair of damaged tissues, MGF contributes to muscle hypertrophy and overall strength development, making it a key factor for athletes and individuals engaged in resistance training.
