Profile Overview

PEG-MGF (Pegylated Mechano Growth Factor) is a synthetic analog of MGF, the 24-amino-acid E-domain peptide of the IGF-1Ec splice variant naturally released in skeletal muscle in response to mechanical damage. PEGylation extends the half-life from minutes to an estimated 24 to 72 hours. MGF has been WADA-prohibited under S2 since 2005. No human interventional trial of PEG-MGF or exogenous MGF has been published. Animal evidence includes satellite cell activation, cardiac protection post-infarction in sheep (Carpenter 2008: 35% less compromised myocardium), and progenitor cell increases in ALS and DMD mouse models. Observational human data shows blunted endogenous MGF expression in elderly versus young men after resistance exercise (Hameed 2003, n=34). The IGF-1 pathway oncology risk is a meaningful theoretical safety concern.
