Who holds the newest Hexarelin report (1 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 Hexarelin purity report we have read (1), one row per report
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.
| Seller | Task | Client on the report | Report date | Result | Batch | |

| Kensingtonlabs | #81975 | Kensingtonlabs.co.uk | 7 Oct 2025 | Hexarelin · 5.92 mg · 99.427% | HXA-509ZT | verify |
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 Hexarelin is, and what it is sold as
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.
| Development status | Development abandoned. Reached phase 2 trials for growth hormone deficiency and was then discontinued; we found no approval in the US, the EU or the UK. |
|---|---|
| Originator | Romano Deghenghi, the named inventor on the patent family and first author of the first indexed paper (Life Sciences, 1994). Rights: Developed by Mediolanum Farmaceutici of Milan with Europeptides of France. The US patents were later assigned to Ardana Bioscience and Mediolanum Pharmaceuticals. |
| Registered clinical trials | 0 on ClinicalTrials.gov |
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.

What regulators say about Hexarelin
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.
We hold no statement from the FDA, MHRA or EMA specifically about Hexarelin on file. Its development and licence sources are listed under the record above.
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 10 October 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.
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.
