What we found
PeptX (peptx.co.uk, domain registered 26 February 2026) is the trading name of PX Reagents Ltd, registered in Scotland (SC890970, incorporated 27 May 2026, West George Street, Glasgow). It sells single vials from UK stock and a 'factory direct' route that ships from outside the UK. Its COA library lists nine results: MOTS-c and BPC-157 from Marfleet, eloralintide and SS-31 from BT Labs, retatrutide 20 mg from Analiza Białek, tirzepatide from Chromate (labelled '3rd-party supply'), and PT-141, ipamorelin and retatrutide 10 mg from Janoshik. Two of those link to Janoshik's server and we opened both on 28 September 2026: task #211039 (PT-141, 99.906%, 10.96 mg) and task #211038 (ipamorelin, 99.653%, 4.81 mg), both ordered 21 July 2026 and analysed 11 August 2026. Both print the client as 'PX' and the manufacturer as Unknown, and neither prints a batch number. 'PX' matches the company's initials and logo but does not name the seller, so under this audit's rule it is not yet an own-name certificate. The results from the other four laboratories carry no verification link.

Questions people ask about PeptX
Is PeptX legit?
PeptX (peptx.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 PeptX publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ Real reports, but not clearly in its own name. PeptX (PX Reagents Ltd, SC890970, Glasgow) publishes nine results from five laboratories. Two are Janoshik reports that verify on Janoshik's website, but they print the client as 'PX', two letters that do not identify the seller on their own.
How do I check PeptX's certificate myself?
Find the certificate on peptx.co.uk and read four things: an independent laboratory is named; the client field names PeptX, 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.
