What is AOD-9604?
AOD-9604 is a short chain of 16 amino acids copied from the tail end of human growth hormone, with one link swapped. Growth hormone itself is 191 links long. This piece covers links 177 to 191, with a tyrosine added at the front in place of the phenylalanine that sits at link 176. That single swap is what separates it from Fragment 176-191, the related product sold alongside it. It has been tested in obese rats and obese mice.

AOD-9604 Research & Reference
What AOD-9604 does in published studies, and how to work with it in the laboratory, are covered in full on two dedicated pages rather than summarised here, so neither the evidence nor the handling detail is cut short.
Certificates of Analysis
Every batch is tested by an independent laboratory before release. The certificate covering this batch of AOD-9604, and its safety data sheet, are below as PDFs, so the figures on this page can be checked against the source.
Frequently Asked Questions
Is AOD-9604 independently tested for purity?+−
Yes. Every batch of AOD-9604 is tested by an independent third-party laboratory using HPLC and MS-UPLC, confirming purity and mass identity before the batch is released. Pure Peptides does not test its own material.
Can I see the Certificate of Analysis before buying?+−
Yes. The Certificate of Analysis for the batch currently in stock can be viewed and downloaded directly on this page, before you place an order. Each certificate states the batch number, the measured purity, and the date of analysis, and can be verified independently with the issuing laboratory using the report number it carries.
What does "Research Use Only" mean?+−
It means AOD-9604 is supplied for in-vitro laboratory research and for no other purpose, and must not be administered to humans or animals. AOD-9604 is legal to purchase in the United States for in vitro and non-clinical laboratory research. It carries no FDA approval or therapeutic indication for human use. AOD-9604 appears in section S2 of the WADA Prohibited List for competitive athletes, a separate consideration from its legal research status. Sold strictly for qualified research use, not human or veterinary administration.
How is AOD-9604 shipped and stored?+−
AOD-9604 ships from US stock with cold-chain packaging and full tracking; orders placed before noon EST on business days are typically dispatched the same business day. On arrival, store the lyophilized powder at -20°C or below, dry and protected from light.
How is AOD-9604 different from Fragment 176-191?+−
AOD-9604 is Tyr-hGH(177-191): it substitutes a tyrosine for the phenylalanine that sits at position 176 of growth hormone. Fragment 176-191 is the unmodified peptide. Both carry the same intramolecular disulfide bridge, so the tyrosine substitution is the structural difference. The two have overlapping but separate published literature, and this site reports each one's findings on its own page.
