What we found
Reta Research is a single-focus retatrutide shop (also GHK-Cu, melanotan 2 and bacteriostatic water) offering discreet next-day UK shipping at GBP prices. It states 'independent third-party analysis confirms identity, purity and composition before release' and 'Verified Purity 99% by HPLC', but no lab is named and no report is published. A near-identical domain, reta-research.co.uk, presents the same 'Research Peptides UK' branding but does not currently resolve, so the two appear to be the same or a mirrored operator. No company registration is shown.

Questions people ask about Reta Research
Is Reta Research legit?
Reta Research (retaresearch.co.uk) is on The Peptide Watch's watch list. It does not publish a certificate of analysis that can be independently verified in its own name, so its quality claims rest on trust rather than checkable evidence. That is not proof of a scam; it means the evidence does not check out.
Does Reta Research publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ 'Independent third-party analysis', but nothing named or published. Reta Research says purity is 'verified 99% by HPLC' via 'independent third-party analysis', but names no laboratory and publishes no certificate you can check.
How do I check Reta Research's certificate myself?
Find the certificate on retaresearch.co.uk and read four things: an independent laboratory is named; the client field names Reta Research, not a supplier; the compound line names the peptide you are buying, not only a batch code; and the report opens on the laboratory's own website from its task number and key (verify.janoshik.com for Janoshik). Then compare the batch number on the report with the one on your vial. The free COA Checker on this site runs the first three checks on a photo of the certificate.
