PEG
PEGylated Mechano Growth Factor // ~7000 Da // Satellite Cell Activator
Extended-release IGF-1 splice variant. Systemic muscle repair via satellite cell recruitment.
PEG-MGF is a PEGylated form of Mechano Growth Factor (MGF), an IGF-1 splice variant produced in response to mechanical stress and muscle damage. PEGylation dramatically extends the half-life from minutes to several days, enabling systemic distribution and whole-body muscle repair rather than the purely local effects of native MGF. Research demonstrates activation of muscle satellite cells, improved recovery from mechanical damage, and enhanced protein synthesis.
