Also known as: PEG MGF, Pegylated MGF
PEG-MGF is a synthetic peptide derived from mechano growth factor (MGF), itself a splice variant of IGF-1. It functions by promoting muscle growth and repair through the activation of the PI3K/Akt signaling pathway. Research into PEG-MGF began as scientists sought to enhance tissue regeneration following injury. This peptide is particularly noted for its prolonged half-life due to pegylation, allowing for sustained biological activity. Today, it is primarily studied for its effects on:
- Muscle regeneration
- Injury recovery
- Tissue repair
- Cellular growth pathways
- Enhanced biological activity
It is also being studied for its potential role in age-related muscle loss.
