Is Pyrox Labs legit? An independent review
Pyrox Labs links 229 Janoshik reports, and both we opened on the laboratory's own site name utherpeptide.com as client and manufacturer, not Pyrox Labs: #226797 (tirzepatide, analysed 2 September 2026) and #101333 (semaglutide, sample received 20 January 2026). A report in another company's name shows that company's batch was tested, not this shop's stock. Checked 17 September 2026: the domain was registered on 29 June 2026 and Pyrox Labs Ltd (Companies House 17321280, London E1) was incorporated on 5 July 2026, yet the certificate page runs back to Janoshik task #91818, months before either existed. The reports carry lot codes in a single supplier's format, such as ZE60-0817 and OZ5-0112, and utherpeptide.com is a separate peptide supplier's website with no UK pricing. The catalogue includes retatrutide, tirzepatide, semaglutide, tesamorelin, selank and MOTS-c; contact is [email protected]. What would move this listing: a report on Janoshik's site that names Pyrox Labs as the client.

Is Pyrox Labs legit? The questions people ask
Is Pyrox Labs legit?
Pyrox Labs (pyroxlabs.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 Pyrox Labs publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ Its certificates are its supplier's, not its own.
How do I check Pyrox Labs's certificate myself?
Find the certificate on pyroxlabs.co.uk and read four things: an independent laboratory is named; the client field names Pyrox 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.
