AOD-9604 vs MOTS-c: Key Research Differences AOD-9604 and MOTS-c differ fundamentally in origin and mechanism AOD-9604 is a fragment of the human growth hormone molecule, studied for its effects on lipid metabolism
Its appeal comes from stability and breadth: BPC-157 stays intact in gastric acid, where most growth-factor peptides break down, and animal studies link it to repair across skin, muscle, tendon, ligament, bone, nerve and the gastrointestinal tract
Plus, theres evidence that restricting calories can increase levels of cortisol, the stress hormone
SomatomedinC mediates growth hormone negative feedback by effects on both the hypothalamus and the pituitary
