AOD-9604 is a synthetic peptide derived from the 176–191 fragment of human growth hormone. It was developed to stimulate fat breakdown (lipolysis) without increasing growth hormone or IGF-1 levels. While clinical trials showed modest fat-loss effects, it does not produce the level of weight loss seen with modern GLP-1 medications like semaglutide or tirzepatide.
