Where to buy Melanotan 2 (MT-2) in the UK: the sellers with a verifiable COA

By Jamie, Editor · The Peptide Watch · updated 4 October 2026

The newest verifiable Melanotan 2 certificate on any UK seller's website is on Lab77Peptides (lab77peptides.uk), analysed 28 Sep 2026 (task #231382 on Janoshik's site); 7 verified sellers hold one covering Melanotan 2, 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 Melanotan 2, 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. Melanotan 2 is a synthetic analogue of alpha-melanocyte-stimulating hormone studied in pigmentation research. It is one of the most widely sold research peptides, and correspondingly one where borrowed or absent certificates are common. 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 Melanotan 2

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

Audit findings, not recommendations. Every entry is a report covering Melanotan 2 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 Melanotan 2 report we have not yet read is not listed.

The 13 verifiable Melanotan 2 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 13 Melanotan 2 certificates show

We have read 13 Janoshik reports covering Melanotan 2, published by 8 UK sellers. Each was opened on Janoshik's own website. 11 of the 13 name the seller itself as the client; the client column in the table above shows the name on the rest. 7 of the 13 are dated within the last six months. The newest is dated 28 Sep 2026 and the oldest 5 Feb 2026.

9 of the reports give a purity figure for Melanotan 2. The figures run from 98.133% to 99.925%, and 8 of the 9 are at 99% or above. 4 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: Lab77Peptides: task #231382, analysed 28 Sep 2026, 10.58 mg recovered at 99.390%, client Lab77peptides.uk; Peptology Labs: task #229667, sample received 4 Sep 2026, 10.38 mg recovered at 99.925%, client PEPTOLOGY LABS LTD; BioVanta Research: task #153920, analysed 25 May 2026, 9.76 mg recovered at 99.771%, client Biovanta Research.

A certificate is a batch document. The lines that matter are the compound (it must say Melanotan 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 Melanotan 2?

As of 4 October 2026, 7: Lab77Peptides, Peptology Labs, BioVanta Research, Peptideprime, Ascendpeptidesuk, Xlpeptides, Imperialpeptides. Each has a report on Janoshik's own website that names the seller as the client and lists Melanotan 2. That is a statement about paperwork, not a recommendation; The Peptide Watch does not recommend anywhere to buy Melanotan 2.

How recent is the newest Melanotan 2 certificate from a UK seller?

The newest we have read is Janoshik task #231382, analysed 28 Sep 2026. It is published by Lab77Peptides 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 Melanotan 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 Melanotan 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 Melanotan 2 a licensed medicine in the UK?

Illegal to sell in the UK as an unlicensed medicine, per the MHRA. Palatin stopped work on it in 2000 and it was never submitted for approval anywhere. The Peptide Watch does not give legal or medical advice.

Why does The Peptide Watch not say where to buy Melanotan 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 Melanotan 2. Listing which sellers publish a certificate you can check, and which publish nothing, is as far as the evidence goes.

The market for Melanotan 2 in the UK

Companies. 13 of the 20 can be matched to a Companies House record; the median company is 7 months old and 10 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 20 have a Trustpilot profile with a score; the median is 4.6, 3 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 Melanotan 2, and what it does not

Papers on PubMed197
Indexed as rat or mouse studies134
Indexed as clinical trials1
Published since 202026
Trials registered on ClinicalTrials.gov1

A university compound whose developers walked away from it. Melanotan II was made at the University of Arizona by Hadley, Hruby and colleagues; its one human study indexed as a clinical trial is a 1996 pilot in three men. PubMed indexes 197 papers, 134 in rodents.

Licensed out, then dropped. Palatin Technologies licensed it for sexual dysfunction, stopped work on it in 2000 and developed bremelanotide instead; a 2008 settlement returned the rights to the university's licensing agent. No phase 3 trial was ever run and it was never submitted for approval.

In the UK it is illegal to sell. The MHRA has said since 2008 that unlicensed melanotan injections and nasal sprays are illegal to supply, has had more than 100 websites suspended, and has logged reports of suspected side effects. That is a stronger statement than 'unlicensed', and it applies to every UK listing.

The Peptide Watch's position on Melanotan 2

Illegal to sell in the UK as an unlicensed medicine, per the MHRA. The Peptide Watch reads the certificates UK sellers publish and does not recommend anywhere to buy Melanotan 2. Sellers on this page are listed by the date of their newest Melanotan 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 Melanotan 2 and links to no shop; this is research-use-only information, not medical or dosing advice.
