PEG-MGF (Pegylated Mechano Growth Factor) is a synthetic variant of IGF-1 (insulin-like growth factor) with a PEG (polyethylene glycol) modification to extend its half-life. It is studied primarily for its role in muscle repair, regeneration, and growth. PEG-MGF activates satellite cells in muscle tissue, stimulating protein synthesis and muscle fiber hypertrophy following mechanical stress or injury.
โ Form: Lyophilized peptide
โ Purity: >99%
โ Origin: Manufactured and tested in the USA
โ Certifications: Certificate of Analysis (COA) included
PEG-MGF promotes muscle regeneration by triggering satellite cell activation and proliferation. It mimics the natural MGF splice variant of IGF-1, which is expressed in response to mechanical overload. The PEGylation protects the peptide from rapid degradation, extending its half-life and making it more viable for research applications involving sustained activity.
