Alternatives to New-U in the UK: sellers you can actually verify

New-U (new-u.io) 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 New-U 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.
