Alternatives to Peptide Vault in the UK: sellers you can verify

By Jamie, Editor · The Peptide Watch · updated 10 July 2026

Peptide Vault (peptidevault.co.uk) does not publish a certificate of analysis that can be verified in its own name, so if you want a UK research-peptide seller whose testing you can check yourself, the verified alternatives are below. The Peptide Watch takes no vendor money and links to no seller's shop.

Peptide Vault peptide Vault (matching Peptide Vault Ltd, Companies House 16606409) sells tirzepatide, retatrutide and GLOW pens plus stacks with GBP pricing, shipping to UK and Northern Ireland only with next-day delivery Mon to Thu. It cites 'trusted third-party laboratories' but names none, and contact is WhatsApp-only, a higher-friction pattern. Companies House shows an ACTIVE PROPOSAL TO STRIKE OFF this company (Peptide Vault Ltd, 16606409).
