Polyethylene Glycol (PEG) Mechano Growth Factor (MGF) is an isoform of Insulin Like Growth Factor 1 (IGF-1) comprised of 24 amino acid residues that is stabilized by a biocompatible polymer coating (PEG).

According to researchers, MGF or peg mechano growth factor has the ability to offer systematic full body benefits. It does this through the increase in muscle cell production. Studies show that MGF is able to enhance recovery of injured or strained muscle tissues as well as increase muscle size. Because of the mechanism that mechano growth factor uses, you can also expect slower protein breakdown and improved muscle growth. While most variations of this natural peptide only last roughly 5 to 7 minutes in the body, modifications done to the synthetic variety mean it last longer in the bloodstream for better results.


A natural form of MGF is expressed in muscle tissues in response to the overburdening or damage of these cells1. MGF has been found to induce the stimulation of repair, regrowth, and the formation of new cells in response to stress2. This process is called hypertrophy (or hyperplasia) and is crucial in the gaining of muscle mass.
