PEG-MGF
PEGylated Mechano Growth Factor
Long-acting version of the muscle satellite cell activator
PEG-MGF is a pegylated version of Mechano Growth Factor with an extended half-life from minutes to hours. The PEG chain provides systemic distribution rather than localised action.

Overview
PEG-MGF was developed to address the extremely short half-life of native MGF. By attaching a polyethylene glycol (PEG) chain, the peptide resists enzymatic degradation and circulates for hours instead of minutes. This allows subcutaneous injection rather than requiring direct intramuscular injection into target muscles. The trade-off is that PEG-MGF loses the localised, site-specific action of native MGF and instead works systemically. It remains a research compound with no human clinical trials.
How it works
Same as native MGF: activates muscle satellite cells through a receptor distinct from IGF-1R, promoting proliferation and fusion with existing muscle fibres. The PEG chain prevents enzymatic degradation, extending the half-life from minutes to approximately 6-8 hours, allowing systemic distribution through subcutaneous injection.
