AOD-9604 (peptide fragment)

AOD 9604 Peptide

AOD 9604 peptide is a synthetic analog of growth hormone designed with the intention of mitigating obesity and aiding weight loss. The peptide is a modified fragment of the growth hormone where the last 16 amino acids (176-191) have been reproduced as a specific peptide, called GH Fragment 176-191 or simply AOD 9604. It also has a tyrosine residue to replace the first amino acid at the N-terminus, which researchers consider to help increase the stability of the peptide.⁽¹⁾

More specifically, AOD 9604 is considered the lipolytic fragment of GH as different parts of the GH molecule appease to have different potentials. For instance, studies suggest that out of its 191 amino acid structure “the N-terminal region exhibits an insulin-potentiating action, while amino acids 108 – 129 of hGH were found to evoke high mitogenic responses.”⁽
