In research literature and supplier catalogues, the terms AOD-9604 and HGH Fragment 176-191 appear with enough regularity — and enough conflation — that clarifying the structural relationship between them is a genuine scientific necessity. These are not interchangeable designations for the same compound. They differ in sequence, molecular weight, and N-terminal chemistry, and those differences…

AOD-9604 is a synthetic peptide fragment derived from the C-terminus of Human Growth Hormone (HGH). Originally developed as part of research into the metabolic properties of growth hormone, it has since become a widely studied compound in biochemical and molecular research settings. Unlike the full HGH molecule, AOD-9604 is valued in research for its selective…
