What we found
River Peptides re-checked 9 September 2026. This vendor had been carried as dead. It resolves on 8.8.8.8, 1.1.1.1 and 9.9.9.9 and returns an HTTP response, which under our own liveness rule counts as alive. The response is a Cloudflare Turnstile challenge. We do not complete bot challenges to gather evidence, so this entry records exactly what can be established without doing so: the site is up and it is closed to inspection. It came to our attention because visitors searched this brand on our own site three times in a week while our page said it was dead.
New As of 13 October 2026 you can leave feedback on your order. Reports are being collected now and will be shown on this page from 1 November 2026, so every seller has the same time to gather them. Written notes appear only after we have read them.

Questions people ask about River Peptides
Is River Peptides legit?
River Peptides (riverpeptides.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 River Peptides publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ Live, but it will not let anyone check it. River Peptides resolves normally and its server responds, but every request is met with a Cloudflare bot-verification challenge, so the storefront cannot be read by us or by any automated check.
How do I check River Peptides's certificate myself?
Find the certificate on riverpeptides.co.uk and read four things: an independent laboratory is named; the client field names River 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.
