Alternatives to My Reta in the UK: sellers you can actually verify
My Reta (myreta.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 My Reta 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.
