The core function of MGF is as a **rapid response system** after muscle injury. When muscles undergo high-intensity training or external force injury, micro-tears in muscle fibers trigger the rapid secretion of MGF, with its concentration increasing more than threefold within 12 hours after injury. It precisely activates dormant muscle satellite cells, promoting their differentiation into mature muscle fibers, while accelerating capillary formation to deliver oxygen and nutrients to the repair area. Experiments have shown that MGF supplementation can increase muscle repair efficiency by 40% and shorten the duration of post-workout muscle soreness by 25%.
Beyond muscle repair, MGF also exhibits **multi-system potential value**. In the field of nerve repair, it can promote the growth of motor neuron axons, helping to restore motor function after nerve injury. In terms of bone health, it can stimulate osteoblast activity and increase bone density, making it particularly suitable for athletes to prevent stress fractures.
However, it must be noted that **there are uncertainties associated with exogenous supplementation**. Current clinical research is still mainly focused on animal experiments, lacking sufficient data on the long-term safety of human supplementation. Excessive supplementation may lead to local tissue hyperplasia. Sports medicine experts emphasize: "The physiological effects of MGF depend on the balance of 'mechanical stimulation + precise secretion.' Regular training is the core of activating endogenous MGF; the risks of blindly supplementing with exogenous MGF are still unclear."
