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.
The Peptide Watch benchmarks every vendor on the same compound, BPC-157, the most common research peptide, as £ per milligram, so prices are directly comparable across all providers. No public BPC-157 price feed was available for this vendor at audit.
