Where to buy AOD-9604 (hGH fragment 176-191) in the UK: the sellers with a verifiable COA

The newest verifiable AOD-9604 certificate on any UK seller's website is on Peptology Labs (peptologylabs.uk), analysed 18 Jun 2026 (task #194959 on Janoshik's site); 4 verified sellers hold one covering AOD-9604, listed newest first below. Of the 450 active UK sellers we audit, 38 (8%) publish their own verifiable Janoshik certificate of analysis, and this page lists which of them hold one covering AOD-9604, newest certificate first. It is a record of paperwork, not a recommendation: The Peptide Watch sells nothing, takes no money from sellers and links to none of them. 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. Purity and identity cannot be judged by eye, so an independent certificate you can check is the only real proof of what is in the vial.

The one test that matters for AOD-9604

Ignore the marketing. The question is simple: does the seller publish a verifiable Janoshik certificate that names the seller itself as the client? If it does, you can confirm an independent lab tested that batch. If it shows an in-house document, a borrowed certificate, or "COA on request", you cannot. Learn the two-minute check in how to verify a Janoshik COA.

Audit findings, not recommendations. Every entry is a report covering AOD-9604 that we opened on Janoshik's own site and that names the seller itself as the client; the date is the analysis date printed on the report where we have read it, otherwise the date the laboratory received the sample. The table below is the same ledger in full, so the two always agree. Not exhaustive: a vendor whose AOD-9604 report we have not yet read is not listed.

The 6 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.

What the 6 AOD-9604 certificates show

We have read 6 Janoshik reports covering AOD-9604, published by 4 UK sellers. Each was opened on Janoshik's own website. All 6 name the seller itself as the client. 5 of the 6 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. 2 reports test for heavy metals or endotoxins instead. 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.

The market for AOD-9604 in the UK

Advertising. Google's Ads Transparency Centre shows 1 of these sellers running ads: Thoroughbredlabs. Paid reach is where a new buyer meets a brand before meeting any certificate.

Companies. 6 of the 16 can be matched to a Companies House record; the median company is 2.7 years old and 2 were incorporated within the last year. A seller with no traceable company is not necessarily dishonest, but there is nobody to hold to its certificate.

Reviews. 5 of the 16 have a Trustpilot profile with a score; the median is 4.4, 2 sit at 4.5 or above and 0 below 3.0. A review score says who collects reviews, not who tests, which is why it sits next to a certificate and never instead of one.

What the research shows for AOD-9604, and what it does not

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.

Who owns AOD-9604, and where it stands

Counts are from PubMed on 15 September 2026 using the queries recorded in our evidence file; "clinical trial" is PubMed's own publication-type index. This is a description of the published record, not medical advice and not an argument for or against use.

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.
