◇ The Peptide Watch, independent vendor audit

Is Corix Research Labs legit? An independent review

corixlabs.co.uk · audited 10 October 2026
Corix Research Labs is on the watch list: its certificate can't be verified in its own name, one of 459 of 500 UK sellers that fail this check.

Corix Research Labs (Corix Research Labs UK Limited, Companies House 15270634, incorporated November 2023, Louth) runs a genuine UK shop selling BPC-157, TB-500, GHK-Cu, AOD-9604 and similar at GBP prices. Its /third-party-testing page names Janoshik Analytical and states every batch is externally tested, but that page is narrative only: it displays no certificate, and the individual product pages, checked directly, show no Janoshik report, no batch identifier and no verification code. A named lab in prose is not the same as a published, verifiable certificate in the seller's own name, so nothing about a given batch can currently be confirmed.

Is Corix Research Labs legit? The questions people ask

Is Corix Research Labs legit?

Corix Research Labs (corixlabs.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 Corix Research Labs publish a real, verifiable Certificate of Analysis?

Not one that can be independently verified in its own name. ⚠ Names Janoshik in policy, shows no certificate. Corix Research Labs describes a '100% batch testing' policy with Janoshik Analytical on its testing page, but its product pages carry no certificate, batch number or verification link, so there is nothing you can independently check.

How do I check Corix Research Labs's certificate myself?

Find the certificate on corixlabs.co.uk and read four things: an independent laboratory is named; the client field names Corix Research Labs, 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.
