PEG-MGF

This product is not intended for weight loss, human consumption, or veterinary use. It is sold for research purposes only. Please handle with care and follow all safety guidelines for the specific chemicals involved.

What Is PEG-MGF Peptide?

Polyethylene Glycol (PEG) Mechano Growth Factor (MGF), commonly referred to as PEG-MGF peptide. It 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). The C-terminal residue sequence of MGF infers the characteristics that make this peptide unique from IGF-1¹.A natural form of MGF is expressed in muscle tissues in response to the overburdening or damage of these cells². MGF has been found to induce the stimulation of repair, regrowth, and the formation of new cells in response to stress³.

PEG MGF Peptide and Muscle Hypertrophy

This process is called hypertrophy (or hyperplasia) and is crucial in the gaining of muscle mass.The natural production of MGF stimulates the recruitment of undamaged cells to give rise to new muscle tissues, while a liver-derived variant of this agent (IGF-1Ea) initiates the upregulation – or positive feedback control – of protein synthesis⁴. Through these biochemical pathways, MGF is thought to be the primary mechanism by which the body naturally produces new muscle tissue.

PEG-MGF in Neuroprotection and Cardiac Repair

Animal studies have shown PEG-MGF as an active neuroprotective agent⁵ and a promoter of conserved skeletal health⁶. Also, reinforcing its functionality as an agent of muscle tissue repair, PEG-MGF has been found to be active in coordinating the repair of heart muscle tissue following myocardial infarction (heart attack)⁷. One study found that human mesenchymal stem cells migrated towards PEG-MGF, highlighting its potential role in cardiac tissue repair. In neonatal rat ventricular stem cells, apoptosis was inhibited with exposure to MGF.

PEG-MGF Peptide vs. IGF-1 — Key Differences

Though IGF-1 and PEG-MGF are very similar in origin and in (partial) structure, the two agents have very different mechanisms of action. Researchers have expressed that these two agents (PEG-MGF peptide & IGF-1 LR3) show great sThough IGF-1 and PEG-MGF are very similar in originynergy and have observed enhanced rates in muscle growth while both IGF-1 LR3 (or IGF-1 DES) and MGF have been administrated together in animal subjects.

PEG-MGF is much more stable than unprotected MGF, which infers a much longer residence time in the bloodstream. Preference for MGF’s ‘burst’ profile or PEG-MGF’s sustained profile of activity must be determined by the research intent.

What is PEG MGF peptide used for in research?

PEG-MGF has been studied as an active neuroprotective agent, a promoter of conserved skeletal health, and an agent of muscle tissue repair. It has also been found to coordinate the repair of heart muscle tissue following myocardial infarction (heart attack).

3
How does PEG-MGF differ from IGF-1?

Though IGF-1 and PEG-MGF are very similar in origin and in partial structure, the two agents have very different mechanisms of action. Researchers have observed that these two agents show great synergy and enhanced rates in muscle growth when administered together in animal subjects.
