Alternatives to UK Peptide Supply in the UK: sellers you can actually verify
UK Peptide Supply (ukpeptidesupply.com) does not publish a certificate of analysis you can verify in its own name. If that is why you are looking for an alternative, the UK sellers further down do, so you can check the testing yourself before you buy. The Peptide Watch takes no vendor money and links to no seller's shop.
Why UK Peptide Supply is on the watch list
UK Peptide Supply (distinct from the separately-listed peptidesupplyuk.co.uk) sells research compounds including Melanotan 2, claiming 'carefully sourced, third-party tested' but naming no laboratory and showing no certificates on the page. It has a Trustpilot presence. Domain registered March 2026.
- Why it is on the watch list: No named lab, nothing to verify
- Trustpilot: 4.6 from 31 reviews, which reflects delivery and service, not what is in the vial
