What we found
Zenterex (trading as Strata Sourcing Ltd, Companies House 16961416, London) is a live UK shop selling BPC-157, TB-500, GHK-Cu, NAD+, MOTS-c, Semax and Selank 'for laboratory research only', with next-day UK delivery at GBP prices. It states 'Certificates of Analysis from independent third-party laboratories are available for every product', but no independent laboratory is named and no certificate is published for inspection, so nothing about a given batch can be independently verified. The trading company is registered, but its peptide testing is not tied to any named lab.

Questions people ask about Zenterex
Is Zenterex legit?
Zenterex (zenterex.com) 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 Zenterex publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ 'COA from independent third-party labs available', no lab named. Zenterex says a certificate is available for every product from 'independent third-party laboratories', but names no laboratory, so nothing can be traced to a lab's own verification.
How do I check Zenterex's certificate myself?
Find the certificate on zenterex.com and read four things: an independent laboratory is named; the client field names Zenterex, 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.
