Alternatives to Tidelabs in the UK: sellers you can actually verify

Tidelabs (tidelabs.co.uk) is on The Peptide Watch's watch list. What its certificate shows, and why it cannot be verified in its own name, is set out in the Tidelabs audit. This page answers the other half of the question: which UK sellers do publish a certificate you can check yourself before you buy. The Peptide Watch takes no vendor money and links to no seller's shop.
