Who holds the newest AOD-9604 report (4 verified UK sellers)
Newest report first. Every report was opened on Janoshik's own website and names the seller as the client. The date is the analysis date printed on the report. The verify link opens the laboratory, never the shop. Audit findings, not recommendations.

Every AOD-9604 purity report we have read (4), one row per report
The 4 verifiable AOD-9604 certificates we have read, newest first
Each row was opened on Janoshik's own site by a real page load and transcribed. The client column is the name the laboratory printed; a certificate counts as a seller's own only when that name is the seller. The report date is the analysis date printed on the report where we have read it, otherwise the date the laboratory received the sample. The verify link opens the laboratory, never the shop. Audit findings, not recommendations.

Why the date on a certificate matters
What a purity figure means
The purity on a Janoshik report is the share of the main peak in an HPLC chromatogram. 99.5% means that 99.5% of what the detector saw was one substance and 0.5% was something else. It is not the amount in the vial: that is the separate quantity line, in milligrams. It does not by itself prove which substance the peak is: that is identity, confirmed by mass spectrometry. And it says nothing about sterility, endotoxins or heavy metals, which are separate tests.
A purity figure printed on a shop page with no report behind it is a claim, not a measurement. Between two reports, the difference that matters is rarely 99.2% against 99.8%; it is whether the report exists at all, names the seller as the client, covers this compound on its own, and is recent.
What AOD-9604 is, and what it is sold as
AOD-9604 is a synthetic fragment of human growth hormone that a pharmaceutical developer took into large obesity trials and then abandoned. It is sold on the strength of that history, so what a certificate says about the vial in front of you is the only current evidence.
| Development status | Development abandoned. Discontinued in February 2007 after a 536-person phase 2b obesity trial showed no significant weight loss. Never approved anywhere. |
|---|---|
| Originator | Monash University, Melbourne, from the growth hormone sequence; developed by Metabolic Pharmaceuticals. Rights: No active developer since Metabolic Pharmaceuticals ended the programme in 2007. |
| Registered clinical trials | 0 on ClinicalTrials.gov |
A drug candidate that failed its decisive trial in 2007. AOD-9604 is a synthetic fragment of human growth hormone that Metabolic Pharmaceuticals of Melbourne took into obesity trials in the 2000s. A 24-week placebo-controlled phase 2b in 536 people did not produce significant weight loss and development stopped in February 2007. That trial was never published. PubMed indexes 22 papers, 3 in rodents and none indexed as a clinical trial; ClinicalTrials.gov lists no registered study.
Nothing has happened since. No company develops it, no trial is registered and no regulator has approved it. What sellers describe as its fat-burning effect is the hypothesis a failed trial was built to test.
For a buyer, the only checkable fact about a vial is a certificate that names the seller and verifies on the laboratory's site.

What regulators say about AOD-9604
In the UK. Not a licensed medicine in the UK. Sold as a research chemical.
We hold no statement from the FDA, MHRA or EMA specifically about AOD-9604 on file. Its development and licence sources are listed under the record above.
What the 4 AOD-9604 certificates show
We have read 4 Janoshik reports covering AOD-9604, published by 4 UK sellers. Each was opened on Janoshik's own website. All 4 name the seller itself as the client. 3 of the 4 are dated within the last six months. The newest is dated 18 Jun 2026 and the oldest 16 Mar 2026.
3 of the reports give a purity figure for AOD-9604. The figures run from 99.273% to 99.788%, and all 3 are at 99% or above. 1 more gives the amount recovered and no purity figure for it, which is usual where the vial holds a blend. A purity figure describes the sample the laboratory received, not every vial from that batch.
Read directly from the newest reports: Thoroughbredlabs: task #149081, sample received 15 May 2026, 5.44 mg recovered at 99.273%, client Thoroughbred Labs; Phoenixbiolabs: task #147240, sample received 13 May 2026, 5.07 mg recovered at 99.465%, client www.phoenixbiolabs.net; Xlpeptides: task #121798, sample received 16 Mar 2026, 4.90 mg recovered at 99.788%, client XL Peptides.
A certificate is a batch document. The lines that matter are the compound (it must say AOD-9604, not only a batch code), the client (the shop, not its supplier) and the analysis date. A new batch is untested until a new report appears.

Questions people ask
Which UK sellers publish a verifiable Janoshik certificate naming AOD-9604?
As of 13 October 2026, 4: Peptology Labs, Thoroughbredlabs, Phoenixbiolabs, Xlpeptides. Each has a report on Janoshik's own website that names the seller as the client and lists AOD-9604. That is a statement about paperwork, not a recommendation; The Peptide Watch does not recommend anywhere to buy AOD-9604.
How recent is the newest AOD-9604 certificate from a UK seller?
The newest we have read is Janoshik task #194959, sample received 18 Jun 2026. It is published by Peptology Labs and names it as the client. A certificate covers one batch, so an old one says little about stock on sale today.
How do I check that a certificate for AOD-9604 is genuine?
Four things: an independent laboratory is named; the client field names the seller you are buying from, not a supplier; the compound line says AOD-9604; and the report's task number and key open the same report on the laboratory's own website (verify.janoshik.com). A branded PDF with no laboratory name and no verification code fails on the first check, however professional it looks. The free COA Checker on this site runs the checks for you.
Is AOD-9604 a licensed medicine in the UK?
Not a licensed medicine in the UK. Sold as a research chemical. Discontinued in February 2007 after a 536-person phase 2b obesity trial showed no significant weight loss. Never approved anywhere. The Peptide Watch does not give legal or medical advice.
Why does The Peptide Watch not say where to buy AOD-9604?
Because the site records paperwork, not recommendations. A verifiable certificate proves that a sample of one batch was tested. It does not prove the vial you receive matches it, and it says nothing about whether anyone should use AOD-9604. Listing which sellers publish a certificate you can check, and which publish nothing, is as far as the evidence goes.
The Peptide Watch's position on AOD-9604
Not a licensed medicine in the UK. Sold as a research chemical. The Peptide Watch reads the certificates UK sellers publish and does not recommend anywhere to buy AOD-9604. Sellers on this page are listed by the date of their newest AOD-9604 certificate and by nothing else. If you can verify a seller's testing, you can at least judge its evidence; if you cannot, you are taking the seller's word for what is in the vial. See how UK testing compares across every seller in the market statistics.
An honest note: a verifiable certificate proves a sample of a batch was tested, not that the specific vial you receive matches it, see what this can and can't tell you. The Peptide Watch sells no AOD-9604 and links to no shop; this is research-use-only information, not medical or dosing advice.
