Where to buy Melanotan 2 (MT-2) in the UK, and how to check it's real
To buy Melanotan 2 in the UK from a seller whose testing you can actually verify, choose one of the 28 UK sellers that publish their own verifiable Janoshik certificate of analysis (of 320 active UK sellers, only 9% do). 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.

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.
