Who holds the newest GHRP-2 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 GHRP-2 purity report we have read (1), one row per report
The one verifiable GHRP-2 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 | #88273 | Kensingtonlabs.co.uk | 14 Nov 2025 | GHRP-2 · 10.32 mg · 99.752% | G2A-302NK | 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 GHRP-2 is, and what it is sold as
GHRP-2 is a synthetic six-amino-acid growth hormone-releasing peptide from the early 1990s. It is approved in Japan as an injection used to diagnose growth hormone deficiency, has no approval we could find in the UK, the EU or the US, and is prohibited by name on the WADA list.
| Development status | Licensed elsewhere, not in the UK, US or EU. Approved in Japan on 22 October 2004 as a diagnostic agent for growth hormone deficiency; we found no approval in the US, the EU or the UK. |
|---|---|
| Originator | Cyril Bowers and colleagues at Tulane University, New Orleans, in joint research with Kaken Pharmaceutical of Japan. A Tulane patent application covering the sequence was filed on 22 August 1991. Rights: Kaken Pharmaceutical holds the Japanese marketing authorisation. A 2004 drug profile says Kaken sublicensed the US and Canada to Wyeth, whose development appears to have been discontinued. |
| Registered clinical trials | 0 on ClinicalTrials.gov |
A diagnostic agent in Japan, and nowhere else. GHRP-2, whose official name is pralmorelin, came out of joint research between Cyril Bowers' group at Tulane University and Kaken Pharmaceutical. Japan approved it on 22 October 2004 as GHRP Kaken 100, an injection used to diagnose growth hormone deficiency, and Kaken still sells it there. Kaken's own documents record no marketing outside Japan.
No approval in the US, the EU or the UK. It does not appear in the FDA or EMA medicines databases or on the UK's emc. The FDA lists it among bulk substances that may present significant safety risks in compounding, saying compounded GHRP-2 "may pose risk for immunogenicity due to the potential for aggregation and peptide-related impurities". Impurities are what a verifiable certificate tests for.
The published record. PubMed indexes 243 papers, 57 of them clinical-trial reports, mostly studies of growth hormone release from the 1990s and 2000s. ClinicalTrials.gov lists no study of it. The 2026 WADA Prohibited List names GHRP-2 (pralmorelin) as banned in sport at all times.

What regulators say about GHRP-2
In the UK. We found no licensed GHRP-2 medicine in the UK; the emc lists no pralmorelin product. Sold as a research chemical. Prohibited in sport.
We hold no statement from the FDA, MHRA or EMA specifically about GHRP-2 on file. Its development and licence sources are listed under the record above.
What the one GHRP-2 certificate shows
We have read one Janoshik report covering GHRP-2, published by one UK seller. It was opened on Janoshik's own website and names the seller itself as the client. It is dated 14 Nov 2025.
One report gives a purity figure for GHRP-2: 99.752%. A purity figure describes the sample the laboratory received, not every vial from that batch.
Read directly from the newest report: Kensingtonlabs: task #88273, analysed 14 Nov 2025, 10.32 mg recovered at 99.752%, client Kensingtonlabs.co.uk.
A certificate is a batch document. The lines that matter are the compound (it must say GHRP-2, 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 GHRP-2?
As of 13 October 2026, one: Kensingtonlabs. It has a report on Janoshik's own website that names the seller as the client and lists GHRP-2. That is a statement about paperwork, not a recommendation; The Peptide Watch does not recommend anywhere to buy GHRP-2.
How recent is the newest GHRP-2 certificate from a UK seller?
The newest we have read is Janoshik task #88273, analysed 14 Nov 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 GHRP-2 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 GHRP-2; 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 GHRP-2 a licensed medicine in the UK?
We found no licensed GHRP-2 medicine in the UK; the emc lists no pralmorelin product. Sold as a research chemical. Prohibited in sport. Approved in Japan on 22 October 2004 as a diagnostic agent for growth hormone deficiency; 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 GHRP-2?
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 GHRP-2. 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 GHRP-2
We found no licensed GHRP-2 medicine in the UK; the emc lists no pralmorelin product. 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-2. Sellers on this page are listed by the date of their newest GHRP-2 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 GHRP-2 and links to no shop; this is research-use-only information, not medical or dosing advice.
