Mechano Growth Factor (MGF) is an isoform of Insulin Like Growth Factor 1 (IGF-1) comprised of 24 amino acid residues. MGF’s C-terminal residue sequence infers the characteristics that make this peptide unique from IGF-11.

Description

Mechano Growth Factor (MGF) is an isoform of Insulin Like Growth Factor 1 (IGF-1) comprised of 24 amino acid residues. MGF’s C-terminal residue sequence 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. 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.

Animal studies have shown MGF as an active neuroprotective agent5 and a promoter of conserved skeletal health6. Also, reinforcing its functionality as an agent of muscle tissue repair, MGF has been found to be active in coordinating the repair of heart muscle tissue following myocardial infarction (heart attack)7.

Product Comparison

Though IGF-1 and 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 show great synergy 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.

MGF has a relatively short half-life relative to PEG MGF, which infers a ‘burst’ action profile, rather than a sustained action profile. Preference for MGF or PEG MGF must be determined by the research intent.
