PEG-MGF is a synthetic peptide composed of a fragment of the growth factor (MGF) and a polyethylene glycol (PEG) chain, which acts as a muscle growth factor. MGF is a naturally occurring peptide produced by muscle cells in response to muscle damage or mechanical stress. MGF stimulates the proliferation and differentiation of muscle cells and activates muscle repair and regeneration processes.

PEG-MGF was designed to increase the stability and duration of MGF by adding a PEG chain. PEG prevents the breakdown of the peptide by proteolytic enzymes, resulting in a longer duration of action of PEG-MGF in the body. In studies, PEG-MGF has shown potential in stimulating muscle growth by increasing the number and size of muscle fibers and improving muscle strength. It is usually combined with HGH


PEG-MGF is a derived form of the IGF-1 (insulin-like growth factor-1), which stimulates myoblasts division and allows for muscle fibers to fuse and mature. This is a process necessary for the growth of adult muscle. The distinction between IGF-1 and MGF is that MGF stimulates myoblasts division through the stimulation of different receptors. Research has demonstrated that PEG-MGF helps increase the muscle stem cell count, so that more may fuse and become part of adult muscle cells.
