What does the research on AOD-9604 investigate?
AOD-9604 is the C-terminal fragment of human growth hormone, residues 176 to 191, and the research interest in it has always been structural: whether a small piece of a large protein can be studied in isolation and behave in its own right rather than as a shorthand for the parent molecule. The fragment is a short chain carrying two cysteine residues that form a disulfide bridge, which is the feature that dominates its analytical behaviour. That bridge is not decoration - it constrains the chain into a loop, and it is the first thing to look at when a preparation does not behave as expected. Because the fragment does not carry the region of growth hormone associated with receptor binding, the literature treats it as its own subject rather than as a substitute for the full protein, and in-vitro studies use it to probe how much of a protein's behaviour survives when the protein is cut down to one segment. This page describes the material and its documentation only.
Who can buy AOD-9604?
AOD-9604 is supplied strictly as a research chemical for in-vitro laboratory research. Products are sold exclusively to qualified researchers and licensed laboratories.
At checkout the buyer confirms that they are 18 or over, are buying in the course of research, and are responsible for handling, storing and disposing of the material in line with their laboratory's procedures. AOD-9604 is not for human or veterinary use.
We only answer questions about specifications, documentation and orders.
How are identity and quality assured?
Each released lot is tested and the result is published, rather than the material being described as high purity on the strength of a supplier's word. Purity is measured by reversed-phase HPLC at an independent laboratory. The laboratory used for every lot published so far is Janoshik Analytical, in the Czech Republic, and the result is stated alongside the measured content against label so the two can be read together.
The report carries the lot number printed on the vial, which is the part that matters. A certificate showing a result without a lot number cannot be tied to the vial in front of you, and a certificate for a different lot tells you nothing about yours. Matching the printed number on the label to the number on the report is a five second check and it is the whole point of publishing both.
Identity confirmation by mass spectrometry is a separate test and is ordered as an add-on, so the figures published here come from RP-HPLC purity testing unless a report says otherwise. Where no report is published for a listing yet, the documentation held for the lot being shipped can be requested before you order. We would rather send you what exists than let you assume a certificate is available when it is not.
Synthesis and supply
Peptide material is built by solid-phase synthesis, purified by preparative HPLC, then lyophilised. Lyophilisation freezes the solution and removes the solvent under vacuum, which is why the vial arrives holding a cake or powder rather than a liquid and why a solvent has to be added before the material can be worked with. Removing water also removes the main route by which a peptide degrades in storage, which is the reason the format is used.
Sequence length and modification are what make batches differ in difficulty. Every coupling step is an opportunity for a truncated or deleted by-product, and a heavily modified or long chain presents more of them, which is why the purity trace rather than the headline figure is what a certificate is read for. Vials are filled and labelled with the lot number, and the lot number is what the report and the verification lookup resolve against.
The disulfide is formed deliberately after chain assembly rather than during it, and a batch that failed to close the bridge would show a two dalton mass difference and a shifted retention time on the report.

Frequently asked questions
Is AOD-9604 supplied for human or veterinary use?
No. AOD-9604 is supplied as a lyophilised powder in a sealed vial and is supplied strictly as a research chemical for in-vitro laboratory research. Products are sold exclusively to qualified researchers and licensed laboratories, and buyers confirm they are 18 or over and purchasing in the course of research. We only answer questions about specifications, documentation and orders.
How is the purity figure measured, and what does it actually tell me?
Purity is measured by reversed-phase HPLC at an independent laboratory, and the result is published with the method conditions rather than as a bare percentage. The figure is the proportion of the UV-absorbing material in the chromatogram that elutes as the target peak. It describes the sample as analysed; it is not a statement about what the material is for. A high figure alongside a clean chromatogram is the useful combination, which is why the report is worth reading rather than the headline number alone.
What documentation comes with a batch?
Each released lot carries a number printed on the vial label and a report stating purity by RP-HPLC, measured content against label, and the testing laboratory. Reports published so far are listed on this page and collected on the certificate hub, and each carries a lot number that can be checked against the vial in front of you. Where a report is not yet published for a listing, ask before ordering and we will send the documentation that exists for the lot being shipped.
How should AOD-9604 be stored?
In the form supplied, as a lyophilised powder, the material is stable kept cold, dry and dark. For powder, that means a freezer at around minus 20 degrees Celsius, desiccated, with the vial sealed and shielded from light, which is how it should stay until you are ready to work with it. Bringing a vial to room temperature before opening avoids condensation on the contents. Once in solution the material is less stable than the powder and should be kept cold and used within a short working window. Choosing a solvent and storage conditions for your own work is your call, not ours.
Do I need bacteriostatic water to prepare it?
A lyophilised powder needs a solvent added before it can be worked with. Bacteriostatic water, which is water with 0.9% benzyl alcohol, is the common choice because the preservative extends the working life of the solution once the vial has been opened, and we supply it in 3ml and 10ml vials. It is not the only option: where a method cannot tolerate benzyl alcohol, use the solvent the method specifies. The choice affects the sample, so it belongs to the researcher.
How and when is an order shipped?
Orders are dispatched from the United Kingdom. An order placed before 4pm on a working day is collected the same day; weekends and bank holidays roll forward to the next working day. UK orders go by tracked DPD next-day delivery, free on orders over 14 pounds and 4.99 pounds below that. Tracking is sent when the parcel is collected, so the first scan is usually visible the same evening.
What is the relationship between AOD-9604 and growth hormone?
AOD-9604 is a sixteen-residue fragment corresponding to residues 176 to 191 of human growth hormone, not growth hormone itself. It does not include the region of the parent protein implicated in receptor binding, and the published literature describes it as not acting through the growth hormone receptor. That is a structural and receptor-pharmacology observation about a fragment, and it is the reason the compound is studied on its own terms rather than as a substitute for the full protein.
Why does the disulfide bridge matter analytically?
Two cysteine residues in the chain oxidise to form a covalent loop, and that loop changes the molecule's shape, its hydrodynamic behaviour and its retention on a reversed-phase column. If the bridge is not closed, or is opened during handling, the mass shifts by two daltons and the peak moves - a small change on paper that is clearly visible in a chromatogram. Any handling that could reduce the bridge, including prolonged exposure to reducing conditions, alters what is being measured rather than merely degrading it.
How is a short fragment different to work with than a large protein?
A sixteen-residue chain is straightforward to assemble and to characterise, and its mass is low enough that identity confirmation is unambiguous. The complications are concentrated rather than spread out: one disulfide, one or two oxidisable residues, and a free acid or amide terminus at the C-terminal end. Each of those is a defined variation that a certificate either does or does not account for.
What should someone check before relying on a batch?
The published purity trace, the measured content against label, and the lot number tying the report to the vial. For a fragment with a disulfide, it is also worth confirming whether the mass figure quoted matches the bridged form, since an unbridged chain has a measurably different mass. Where a report is not published for a listing, ask for the documentation held for the lot being shipped rather than assuming it exists.
Why does the fragment stop where it does?
Because it reproduces the C-terminal sixteen residues of growth hormone and nothing else. The boundary is what defines the molecule: a chain beginning one residue earlier or ending one residue later would be a different peptide with a different mass, and a certificate should match the stated span rather than a general description. Identity for a fragment is largely a question of where the chain begins and ends.
Could this material be mistaken for growth hormone itself?
Not on any measurement. A sixteen-residue fragment is a small molecule beside the full 191-residue protein, its mass differs by an order of magnitude, and it does not carry the region of the parent protein associated with receptor binding. The two are separated easily by mass and by retention, and the literature treats the fragment as its own subject rather than as a stand-in for the protein.
