Pegylated form of Mechano Growth Factor (MGF) — the 24-aa C-terminal E-peptide from the IGF-1Ec splice variant, transiently upregulated in muscle after mechanical loading. Studied preclinically for satellite-cell activation and muscle repair; distinct from mature IGF-1 and IGF-1 LR3. Not FDA-approved; WADA-prohibited.

Research-grade PEG-MGF ranges from $13.20/mg to $20.00/mg across 7 verified sources, a 34% spread per mg.
How are PEG-MGF prices verified on Disclosed Labs?
Every listed vendor holds a Grade C or better trust score, computed independently from lab Certificates of Analysis — not from payments or sponsorships. Prices are scraped and fact-checked daily. Vendors cannot pay to improve their ranking.
Check formulation: Lyophilized powder requires reconstitution before use. Pre-mixed solutions are more convenient but may have a shorter shelf life and higher prices.
Compare per-mg cost: Different strengths and quantities make direct price comparison difficult. Calculate the per-milligram cost to find the true best value.
Verify COAs: Look for vendors that publish per-batch Certificates of Analysis from named, accredited labs. Use the Full safety panel filter to require endotoxin, sterility, and heavy-metals testing on the current batch — not just HPLC purity.
Yang and Goldspink (FEBS Lett 2002, PMID 12095637) established that the MGF E-peptide promotes myoblast proliferation and delays terminal differentiation through a receptor distinct from IGF-1R, separating MGF pharmacology from mature IGF-1. Kandalla et al. (Mech Ageing Dev 2011, PMID 21354439) showed the 24-aa MGF E-peptide activates human muscle progenitor cells and enhances their fusion potential even from older donors. Qin et al. (Mol Cell Biochem 2012, PMID 22875667) confirmed MGF drives satellite-cell proliferation while inhibiting differentiation by down-regulating MyoD and p21. Comprehensive reviews by Matheny, Nindl & Adamo (Endocrinology 2010, PMID 20130113) and Zabłocka, Goldspink et al. (Front Endocrinol 2012, PMID 23125840) summarize the evidence across muscle, cardiac and neural tissue and caution that MGF's receptor, in vivo pharmacokinetics, and safety profile remain incompletely characterized. No randomized controlled human trials of PEG-MGF have been published. MGF and IGF-1 analogs are prohibited at all times under the WADA Code.
