What we found
Onvay Labs (onvaylabs.co.uk; Onvay Ltd, Companies House 17224833, incorporated 17 May 2026 at 66 Paul Street, London EC2A 4NA, a virtual-office address shared with other listed vendors) sells retatrutide, BPC-157, GHK-Cu and more with GBP pricing. It claims 'every batch independently tested by Janoshik, greater than 99%', but its Lab Reports page is COA-on-request: certificates are 'shared privately' by email with your order number, justified by the claim that public reports 'get copied and tampered with'. No verify.janoshik.com link exists, so the client named on any certificate cannot be checked. Both company and domain are brand-new. ChatGPT has recommended it as a top UK source despite this.

Questions people ask about Onvay Labs
Is Onvay Labs legit?
Onvay Labs (onvaylabs.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 Onvay Labs publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ Names Janoshik but COAs are 'email-only'. Onvay Labs (Onvay Ltd, Companies House 17224833) says every batch is Janoshik-tested but publishes no verifiable certificate, sharing reports 'privately by email' on the excuse that public ones 'get tampered with'.
How do I check Onvay Labs's certificate myself?
Find the certificate on onvaylabs.co.uk and read four things: an independent laboratory is named; the client field names Onvay 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.
