What Is AOD-9604? A Research Overview
A plain-language research overview of AOD-9604 — what the modified hGH fragment is, why it's studied, and how purity is verified. Research use only.

AOD-9604 is a research peptide derived from the growth-hormone molecule and frequently studied in metabolic science. This overview covers what it is and what to look for when sourcing it.
What AOD-9604 Is
AOD-9604 is a modified synthetic fragment corresponding to the C-terminal region (amino acids 176-191) of human growth hormone — the segment associated in the literature with lipid metabolism — stabilised with an added tyrosine residue. It is a fragment, not full-length growth hormone.
Why Researchers Study It
Researchers use AOD-9604 in laboratory models of lipid metabolism and adipocyte signalling, and in comparative fragment studies. All such work is preclinical and laboratory-scale.
How It Is Characterised in the Lab
Identity and quality are confirmed analytically rather than assumed. A credible research supply confirms identity by mass spectrometry (MS) and purity by HPLC — typically 99%+ — through an accredited (ISO 17025) third-party laboratory, with a per-batch Certificate of Analysis (COA) tied to the exact lot. The CAS reference is 221231-10-3.
