Alternatives to Biolabshop in the UK: sellers you can verify

Biolabshop (biolabshop.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.

Biolabshop states its peptides are 'third-party tested' / 'lab tested' to ≥99% but never names the lab and publishes no verifiable certificate. A purity claim with no lab, no document and no verification link is just a number on a product page, the buyer is asked to take quality entirely on trust. Aggravating: runs contact/orders through WhatsApp; also sells SARMs.
