AOD9604, short for “Anti-Obesity Drug 9604,” is a synthetic peptide fragment derived from the C-terminal region of human growth hormone (hGH). It consists of amino acids 176 through 191 of hGH, with an additional tyrosine residue at the N-terminus. Its molecular formula is C₇₈H₁₂₃N₂₃O₂₃S₂, and it has a molecular weight of approximately 1815.12 g/mol. The peptide contains a disulfide bridge between two cysteine residues, which stabilizes its three-dimensional structure.

AOD9604 was first developed in the 1990s. The goal was to isolate the region of growth hormone of interest to metabolic researchers while excluding the remainder of the full-length hormone sequence. It is classified as a modified peptide fragment and is supplied as a white to off-white lyophilized (freeze-dried) powder that is readily soluble in water. The U.S. FDA granted it GRAS (Generally Recognized As Safe) status in 2014 as a food ingredient.
