PEG-MGF is the long-acting, pegylated version of Mechano Growth Factor (MGF / IGF-1Ec). The covalent attachment of a 20–30 kDa linear or branched PEG chain to the N-terminus dramatically extends plasma half-life from minutes (native MGF) to several days while preserving full biological activity. This allows systemic delivery with sustained exposure, making it ideal for models requiring prolonged satellite cell proliferation and muscle regeneration without repeated local injections. First described in 2004–2006 as an improvement over native MGF, PEG-MGF is the preferred isoform for whole-body or neurological repair studies. This research-grade lyophilised peptide is synthesised under strict quality controls and provided with full analytical documentation.
