What is AOD-9604, and what is it used for?
AOD-9604 is also listed and searched as AOD9604, hGH fragment 176-191 analogue, AOD 9604 peptide. They all mean the same compound. Supplier lists write it as AOD-9604 peptides or peptide AOD-9604 as well; every one of those is this record. A name is not a test, which is why the lot record further down counts for more than the wording on a label.
Chemically: molecular formula C78H123N23O23S2, average mass 1815.1 g/mol (PubChem CID 71300630). Those figures are what the identity test on a certificate is read against.
A man-made peptide matching the tail end of human growth hormone.
A piece of the hormone rather than the whole thing, and it does not carry growth hormone’s full range of effects. The published accounts of how it works are not settled.
It appears in a limited set of animal and early human studies about that piece of the hormone.
No approved drug product. Supplier copy routinely credits it with the pharmacology of whole growth hormone, which the primary research does not support.

The AOD-9604 certificate: lot, purity, identity, and how to verify it
A certificate answers identity, purity and net content as three separate questions, each with the method that produced it and the date it was run, how to read one covers what each field does and does not cover. For AOD-9604 that means a mass spectrum landing on 1,815.1 g/mol for C78H123N23O23S2, the figure published against PubChem CID 71300630. The cataloged form is AOD-9604, and the identity test resolves to that rather than to a related molecule with a similar name.
| Size | Lot | Identity method | Purity | Endotoxin · sterility · fentanyl | Test date |
|---|---|---|---|---|---|
| 5mg | LF-04A-2609 | LC-MS | 99.447% (RP-HPLC, C18, DAD @ 214 nm) | Pass · pass · not detected | 2026-10-07 |
Testing by Kovera Labs. Every batch tested on or after October 1, 2026 includes endotoxin, sterility and fentanyl screening, in addition to identity, purity and net content. Open the report, then confirm it on the issuing laboratory's own site. If the identifier does not resolve there, or resolves to a different lot than the one printed on your vial, the document is worthless however convincing it looks.

The lot number on the certificate must match the lot printed on the vial you received. That match is the only thing tying the document to your material. Net content is reported separately from purity, because a vial can be highly pure and still hold less material than its label states.
Is AOD-9604 legal? FDA status, and what this listing is
FDA status, and what this listing is Not an FDA-approved drug product
The FDA has not approved this compound for anything, and nothing in this catalog is a medicine.
Status verified 2026-08-25. Check the primary source before relying on this summary.
Whether AOD-9604 is legal depends on what it is being used for and where. It is sold as laboratory material under the research-use restriction below. Being listed is not an approval, and not a claim that it is safe, effective or right for any purpose. LabFirst is not a pharmacy or a compounding facility, this vial is not a compounded medicine, and no prescription is involved, because it is not sold for use in anyone. Sports bodies keep their own prohibited lists; whether a substance is banned in competition is a question for the relevant anti-doping authority, not for a supplier.
AOD-9604 research: what the published studies examine
Status: No FDA-approved application. This compound is sold as laboratory material. Where research on it has been published, it sits at the animal, cell or early-human stage, and this record does not summarize what it found. A supplier is not a neutral judge of evidence about its own catalog.
AOD9604 is a man-made copy of the tail end of human growth hormone, building blocks 176 to 191, with a tyrosine added at the front. The idea behind it is genuinely interesting: work in the 1990s suggested growth hormone’s fat-breakdown activity sits in one distinct section, separate from the section that drives growth and disturbs blood sugar. If that split held, a fragment could do the fat part without the insulin resistance that limits growth hormone itself. AOD9604 was built to test that idea.
It does not raise IGF-1 and does not work through the growth hormone receptor in the usual way, which is why it sits apart from the other growth-hormone-related compounds here rather than alongside them.
| Reported observation | Model | Source |
|---|---|---|
| Obese Zucker rats given 500 micrograms per kilogram by mouth for 19 days put on less than half the weight of untreated animals (15.8 grams against 35.6), with more fat breakdown in fat tissue. Unlike long-term treatment with whole growth hormone, a clamp test showed no harm to insulin sensitivity, which is the exact separation the compound was designed to achieve. | obese Zucker rats, 19 days, with euglycaemic clamp | Ng and colleagues, Metabolic studies of a synthetic lipolytic domain (AOD9604) of human growth hormone, Hormone Research (2000) |
| A development review from the time records the compound in phase IIa obesity trials as of February 2002. Development carried on into later obesity trials, no regulator ever approved an obesity product, and the compound was later pointed at other uses. | development review of the clinical program | Wilding, AOD-9604 Metabolic, Current Opinion in Investigational Drugs (2004)The review captures the program mid-flight. What matters now is where it ended, which is without an approval. |
Open questions. The important fact about AOD9604 is about outcome, not mechanism: it went through human obesity trials and never produced an approved product. That is the single most informative thing known about it, and it is missing from essentially all supplier copy, which still quotes the rat fat-breakdown work as though the human program never happened. A compound that failed to get through development for the very thing it was designed for has been tested more thoroughly than most things in this catalog and has less to show for it.
Two more points. The rat result above used the oral route, which is unusual for a peptide and does not carry over to other routes. And the founding idea, that growth hormone’s fat-burning section separates cleanly from the rest, is still argued over rather than settled.
Each row above describes an observation in the stated model. None of it describes what AOD9604 would do in a person or an animal outside that model, and none of it is a recommendation to use it for anything.
How to store AOD-9604: refrigeration and shelf life
Keep the sealed vial cold and out of the light and it stays as it left the lab. Once it is mixed into a solution, how long it holds up depends on the compound, what it was mixed with, how strong the solution is and how cold it is kept — too many variables for anyone to print one shelf life on a label. So laboratories write the date on whatever they prepare and keep their own record of it.
For solution preparation arithmetic on the bench, concentration, per-graduation values and molarity, use the vial concentration calculator, which opens with the AOD9604 sizes stocked here already loaded. It covers laboratory measurement only and contains no administration guidance.
