What we found
Peptrion Labs checked 1 October 2026: peptrion.co.uk is a live WooCommerce storefront (GBP pricing) trading as Peptrion Labs, with its own structured-data (schema.org) address confirming Birmingham, England, B16 8PF. It sells research peptides including BPC-157, TB-500, retatrutide, tirzepatide and GHK-Cu. Its FAQ says "verified documentation is provided for the relevant batch in the Documentation section where applicable," but no product page checked carried an actual certificate file, a named laboratory, or a verify.janoshik.com link with a key. No company registration number is stated on the site. What would move this listing: a named lab plus an openable own-name Janoshik report, or a confirmed Companies House match.
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 Peptrion Labs
Is Peptrion Labs legit?
Peptrion Labs (peptrion.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 Peptrion Labs publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. Peptrion Labs (peptrion.co.uk) is a live UK storefront based in Birmingham selling research peptides including BPC-157, TB-500, retatrutide and GHK-Cu. It refers to a Documentation section for batch paperwork but names no testing laboratory and publishes no openable verify.janoshik.com link.
How do I check Peptrion Labs's certificate myself?
Find the certificate on peptrion.co.uk and read four things: an independent laboratory is named; the client field names Peptrion 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.
