MGF (Mechano Growth Factor)

Research profile · How we handle evidence

MGF (mechano growth factor) is an IGF-1 splice variant (often described as IGF-1Ec/E-peptide) associated with the cellular response to mechanical stress. In research models, it’s studied for effects on muscle stem (satellite) cell activation and repair signaling. Evidence is mostly preclinical.

Overview

MGF is a short-lived peptide fragment produced from the IGF-1 gene via alternative splicing. In muscle, it’s discussed as part of the signaling chain that helps satellite cells respond after training or tissue stress.

pH & Mixing

10.8

Peptides reconstituted at very different pH levels can destabilize when combined in the same syringe, which lowers how much of the peptide your body actually absorbs. If you're unsure whether two peptides are close enough in pH, reconstitute and inject them separately.

A dedicated compatibility check between two specific peptides is coming to the Compare tool. This section covers this peptide's pH only.
