Onvay Labs 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.
See the full audit. This is the short answer; the full Onvay Labs dossier has the certificate check with a live verification link, the Companies House record, pricing against the market and the complete checklist.
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.
You cannot independently verify its testing today. A good delivery reputation is not the same as a verifiable certificate; the two are unrelated. Until Onvay Labs publishes an own-name certificate you can check on an independent lab's website, you are taking its quality on trust.
The Peptide Watch does not assert that. What is observable is the reason it sits on the watch list: 'coa on request', nothing published. Being unverifiable is a reason for caution, not proof of fraud.
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
