Alternatives to Proforma Peptides in the UK: sellers you can actually verify

Proforma Peptides (proformapeptides.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 Proforma Peptides audit. This page answers the other half of the question: which UK sellers do publish a certificate you can check yourself before you buy.
