Is Opti Peptides legit? The questions people ask
Is Opti Peptides legit?
Opti Peptides (optipeptides.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 Opti Peptides publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ Registered UK company, but no COA and no lab named. Opti Peptides Ltd (Companies House 16852554) has a live catalogue but only claims 'appropriate testing', with no COA and no laboratory named.
How do I check Opti Peptides's certificate myself?
Find the certificate on optipeptides.co.uk and read four things: an independent laboratory is named; the client field names Opti Peptides, 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.
