PEG-MGF (Pegylated Mechano Growth Factor) is a variant of IGF-1 (Insulin-like Growth Factor) which leads to an increase in the muscle cells necessary for adult muscles to continue growth beyond their genetic limit. Like other forms of IGF-1, PEG-MGF (also known as IGF-1ec) creates new muscle cells and stimulates muscle growth by promoting nitrogen retention and increasing protein synthesis.
PEG-MGF differs from regular MGF as it has undergone a process of “Pegylation” which extends its half-life from less than 30 minutes to several days. Useful For: Persons looking to stimulate growth in certain (usually lagging) muscles.
Neurological research has shown that utilizing PEGylated MGF resulted in a longer more stable acting version of the MGF peptide in serum/blood. The difference between IGF-1 and MGF is that MGF stimulate myoblasts division through stimulation phentermine of different receptor
PEGylated protein (PEG-MGF) is the one that has Polyethylene Glycol added to it. The role of the Polyethylene Glycol molecule is to preserve the integrity of the Mechano Growth Factor. Unlike the naturally produced Mechano Growth Factor, the injected MGF needs to enter the circulatory system. That is where the problem for the MGF arises. MGF is not stable in such environment and in order to be able to reach its final destination and fulfill its role it needs to be PEGylated (and turned into PEG-MGF). Polyethylene Glycol serves as a kind of a shell protecting the MGF from reacting to its surroundings before it reaches its final destination. It makes the PEG-MGF much more stable and long-lasting than Machano Growth Factor could be on its own.
