AOD-9604 is a synthetic peptide fragment of the C-terminal region (residues 176-191) of human growth hormone, studied in research for its lipolytic and metabolic-pathway activity in experimental models.
AOD-9604 is a synthetic peptide based on the C-terminal region of human growth hormone, specifically a tyrosine-bearing analogue of the 176-191 fragment (Tyr-hGH 177-191). It carries the molecular formula C78H123N23O23S2, a molecular weight of 1815.1 g/mol, and the CAS number 221231-10-3. Kovalabs supplies it as a lyophilised research material.
Because it is a structural relative of HGH Fragment 176-191, AOD-9604 is sometimes catalogued alongside it as a reference standard. It is a research chemical only and is not a medicine.
AOD-9604 is not a controlled drug under the Misuse of Drugs Act 1971, and it is not a licensed medicine in the UK. Kovalabs supplies it strictly as a research material for laboratory use, not for human or veterinary consumption. It must not be administered to people or animals. Purchasers are responsible for complying with the laws and institutional rules that apply to handling research chemicals in their jurisdiction.
Every batch is released only after independent analytical testing. Purity is assessed by HPLC at 99% or higher, and identity is confirmed by HPLC retention-time matching (HPLC-RTM) against a reference standard and the verified identifiers: CAS 221231-10-3, PubChem CID 71300630, and molecular formula C78H123N23O23S2. Because quality varies between suppliers, a Certificate of Analysis documents these results so the material can be verified before use in research. You can review our published records on the CoA page.
The published literature investigates AOD-9604 as a fragment-derived peptide in pre-clinical metabolic-pathway studies, conducted in vitro and in animal models. None of this establishes any benefit, effect or outcome in humans, and AOD-9604 is not a licensed medicine. For a referenced overview of the study designs and pathways involved, see the AOD-9604 research monograph. Full terms are set out in our research disclaimer.
AOD-9604 is manufactured by solid-phase peptide synthesis and supplied as a white to off-white lyophilised powder. For laboratory handling it is typically reconstituted with bacteriostatic water and held at 2-8C once in solution; the sealed lyophilised vial is stored at -20C, dry and protected from light. It sits within our metabolic research category alongside related materials such as MOTS-c and Cagrilintide. Supplied for laboratory research use only; not for human or veterinary use.

Easy, straight forward, well priced
great quality and an impressive service. Used many times. Wouldn't go anywhere else.
Highly recommend.
For context, I’ve used many peptide companies over the years. And I can confidently say kovalabs sit in their own lane. The efforts they go through to get ISO testing is remarkable, more importantly the results themselves are also consistently superb. Shipping has always arrived next day, packaging is professional and packed securely. With nice personal touches too. Support team are fantastic also. The only company I’d recommend for peptides moving forward.
Most transparent provider in the UK
I’ve been using kovalabs for a few weeks but before my first order I did a LOT of research, and chose these as they are by far the most transparent and stringent provider in the UK, by a country mile. This is now my 4th order, and every single time without fail the communication is outstanding, the quality is as expected - superb. And prices remain highly competitive especially for the assurance you’re getting high quality, tested products. I’ve recommended to everyone I know.
100% the best peptide company I've dealt with for peps.This company stands behind it's products and it's service quite boldly, and understandably so. The products themselves look amazing and very professional, and the quality is far beyond what I’ve had from any other pep company in the uk. On my last order, I did have an issue with Royal Mail, in which I then emailed customer support, and Sophie put it right for me on the exact same day, very impressed. They've earned a repeat customer from me!
Delivery was super quick, communication throughout was outstanding. Very reassuring company and also transparent, I’ll continue to buy from here moving forward.
VERY refreshing to have found such a great company. Feels very personal, hats off to Taylor and the team. Great work.
Faultless!
Cannot fault these guys, from ordering to delivery to product quality. 3rd order and always outstanding service. Products are proving great for my research too, best provider around. Wont go anywhere else now.
