Where to buy GHRP-6 (growth hormone-releasing peptide 6) in the UK: the sellers with a verifiable COA

The newest verifiable GHRP-6 certificate on any UK seller's website is on Thoroughbredlabs (thoroughbredlabs.co.uk), analysed 18 Aug 2026 (task #222877 on Janoshik's site); 3 verified sellers hold one covering GHRP-6, 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 GHRP-6, 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. GHRP-6 is the 1984 laboratory hexapeptide that founded the growth hormone secretagogue class. It was used in academic studies and as a diagnostic test for growth hormone deficiency, was never developed into a medicine by any company, and 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 GHRP-6

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 450 active UK research-peptide sellers we audit, only 38 (8%) publish their own verifiable Janoshik certificate. Any of them is where you can actually verify testing, for GHRP-6 or any compound. A few: Lab77Peptides · Peptology Labs · Biovanta · Camo Chem · Biohackpeptides · Zenic Labs.

Audit findings, not recommendations. Every entry is a report covering GHRP-6 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 GHRP-6 report we have not yet read is not listed.

The 3 verifiable GHRP-6 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 3 GHRP-6 certificates show

We have read 3 Janoshik reports covering GHRP-6, published by 3 UK sellers. Each was opened on Janoshik's own website. All 3 name the seller itself as the client. 1 of the 3 is dated within the last six months and 1 is more than a year old. The newest is dated 18 Aug 2026 and the oldest 22 Aug 2025.

All 3 reports give a purity figure for GHRP-6. The figures run from 98.880% to 99.376%, and 2 of the 3 are at 99% or above. A purity figure describes the sample the laboratory received, not every vial from that batch.

Read directly from the newest reports: Thoroughbredlabs: task #222877, sample received 18 Aug 2026, 4.34 mg recovered at 98.880%, client Thoroughbred Labs; Kensingtonlabs: task #88274, analysed 14 Nov 2025, 9.07 mg recovered at 99.376%, client Kensingtonlabs.co.uk; Xlpeptides: task #76136, sample received 22 Aug 2025, 5.00 mg recovered at 99.333%, client XL Peptides.

A certificate is a batch document. The lines that matter are the compound (it must say GHRP-6, 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 GHRP-6 in the UK

Advertising. Google's Ads Transparency Centre shows 2 of these sellers running ads: Kensingtonlabs, Thoroughbredlabs. Paid reach is where a new buyer meets a brand before meeting any certificate.

Companies. 3 of the 5 can be matched to a Companies House record; the median company is 2.7 years old and 0 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.

What the research shows for GHRP-6, and what it does not

The 1984 laboratory peptide that founded a drug class. Cyril Bowers and Frank Momany at Tulane described GHRP-6 in 1984 as the first synthetic peptide that released growth hormone in animals and then in people, years before its receptor, the ghrelin receptor, was known. PubMed indexes 703 papers, 359 in rodents, and 47 clinical-trial reports, mostly 1990s physiology and diagnostic studies: a Lancet paper in 2000 tested GHRH plus GHRP-6 as a diagnostic test for growth hormone deficiency in adults.

Never developed into a medicine. No company took GHRP-6 through approval; the field moved on to non-peptide secretagogues such as MK-677 and to later peptides such as ipamorelin. ClinicalTrials.gov lists no registered study of GHRP-6 alone. Cuba's Center for Genetic Engineering and Biotechnology studies it combined with epidermal growth factor for stroke, a separate combination product. The 2026 WADA Prohibited List names GHRP-6 as banned at all times.

What a certificate can tell you. The two purity reports we read recovered 4.34 mg (98.880%) and 5.00 mg (99.333%) on 5 mg labels.

Who owns GHRP-6, 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 GHRP-6

Not a licensed medicine in the UK. Sold as a research chemical. Prohibited in sport. The Peptide Watch reads the certificates UK sellers publish and does not recommend anywhere to buy GHRP-6. Sellers on this page are listed by the date of their newest GHRP-6 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.
