Where to buy Hexarelin (examorelin) in the UK: the sellers with a verifiable COA
The newest verifiable Hexarelin certificate on any UK seller's website is on Kensingtonlabs (kensingtonlabs.co.uk), analysed 7 Oct 2025 (task #81975 on Janoshik's site); 1 verified seller holds one covering Hexarelin, listed newest first below. Of the 446 active UK sellers we audit, 38 (9%) publish their own verifiable Janoshik certificate of analysis, and this page lists which of them hold one covering Hexarelin, 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. Hexarelin is a synthetic six-amino-acid growth hormone-releasing peptide first described in 1994. Its Italian developer took it to phase 2 trials and stopped; we found no approval for it as a medicine anywhere we checked, and it is prohibited by name on the WADA list. 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 Hexarelin
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.
Which UK sellers publish a verifiable COA
Of the 446 active UK research-peptide sellers we audit, only 38 (9%) publish their own verifiable Janoshik certificate. Any of them is where you can actually verify testing, for Hexarelin or any compound. A few: Lab77Peptides · Peptology Labs · Biovanta · Camo Chem · Biohackpeptides · Zenic Labs.

Verified UK vendors with a confirmed Hexarelin Janoshik certificate (1)
- Kensingtonlabs kensingtonlabs.co.uk · newest Hexarelin report 7 Oct 2025 · task #81975
Audit findings, not recommendations. Every entry is a report covering Hexarelin 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 Hexarelin report we have not yet read is not listed.
The one verifiable Hexarelin certificate we have read
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 one Hexarelin certificate shows
We have read one Janoshik report covering Hexarelin, published by one UK seller. It was opened on Janoshik's own website and names the seller itself as the client. It is dated 7 Oct 2025.
One report gives a purity figure for Hexarelin: 99.427%. A purity figure describes the sample the laboratory received, not every vial from that batch.
Read directly from the newest report: Kensingtonlabs: task #81975, analysed 7 Oct 2025, 5.92 mg recovered at 99.427%, client Kensingtonlabs.co.uk.
A certificate is a batch document. The lines that matter are the compound (it must say Hexarelin, 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 Hexarelin?
As of 29 September 2026, one: Kensingtonlabs. It has a report on Janoshik's own website that names the seller as the client and lists Hexarelin. That is a statement about paperwork, not a recommendation; The Peptide Watch does not recommend anywhere to buy Hexarelin.
How recent is the newest Hexarelin certificate from a UK seller?
The newest we have read is Janoshik task #81975, analysed 7 Oct 2025. It is published by Kensingtonlabs 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 Hexarelin 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 Hexarelin; 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 Hexarelin a licensed medicine in the UK?
We found no licensed hexarelin medicine in the UK: neither the MHRA products site nor the emc lists one. Sold as a research chemical. Prohibited in sport. Reached phase 2 trials for growth hormone deficiency and was then discontinued; we found no approval in the US, the EU or the UK. The Peptide Watch does not give legal or medical advice.
Why does The Peptide Watch not say where to buy Hexarelin?
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 Hexarelin. Listing which sellers publish a certificate you can check, and which publish nothing, is as far as the evidence goes.
What the research shows for Hexarelin, and what it does not
| Papers on PubMed | 293 |
|---|---|
| Indexed as rat or mouse studies | 113 |
| Indexed as clinical trials | 58 |
| Published since 2020 | 19 |
| Trials registered on ClinicalTrials.gov | 0 |
An Italian growth hormone-releasing peptide from the 1990s. Hexarelin, whose official name is examorelin, was first described in 1994 by Romano Deghenghi and colleagues and taken into human studies by Mediolanum Farmaceutici of Milan. PubMed indexes 293 papers, 113 of them in rats or mice and 58 clinical-trial reports, most of them 1990s studies of growth hormone release.
It stopped at phase 2. Published reviews list hexarelin as having reached phase 2 for growth hormone deficiency and then been discontinued. We found no approval for it in US, EU or UK records, and ClinicalTrials.gov lists no study of it.
Banned in sport by name. The 2026 WADA Prohibited List names examorelin (hexarelin) among the growth hormone-releasing peptides prohibited at all times.

The Peptide Watch's position on Hexarelin
We found no licensed hexarelin medicine in the UK: neither the MHRA products site nor the emc lists one. Sold as a research chemical. Prohibited in sport. The Peptide Watch reads the certificates UK sellers publish and does not recommend anywhere to buy Hexarelin. Sellers on this page are listed by the date of their newest Hexarelin 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 Hexarelin and links to no shop; this is research-use-only information, not medical or dosing advice.
