AOD-9604 is a synthetic research peptide derived from the C-terminal region of human growth hormone and consists of amino acids 176–191 with an additional tyrosine residue. It was developed to isolate and investigate specific metabolic signaling characteristics associated with this region of the growth hormone molecule without reproducing the full biological activity of growth hormone.

AOD-9604 research has focused primarily on pathways associated with lipid metabolism and cellular energy regulation. Researchers have investigated its relationship with biological mechanisms involved in lipolysis, lipid storage, and the regulation of metabolic activity within adipose tissue models.

Another area of AOD-9604 research involves understanding how specific fragments of larger peptide hormones can retain selected signaling characteristics. Laboratory studies have used AOD-9604 to investigate structure-function relationships between growth hormone sequences and downstream metabolic pathways.

AOD-9604 has a molecular weight of approximately 1,815 g/mol and is synthetically produced for controlled research applications. It is typically supplied as a white, lyophilized powder for laboratory investigation involving lipid metabolism, cellular energy signaling, and related biochemical pathways.
