Is Zenterex legit? An independent review
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.

Is Zenterex legit? The questions people ask
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.
Can I trust Zenterex, and is it a good supplier?
You cannot independently verify its testing today. A good delivery reputation is not the same as a verifiable certificate; the two are unrelated. Until Zenterex publishes an own-name certificate you can check on an independent lab's website, you are taking its quality on trust.
Is Zenterex a scam?
The Peptide Watch does not assert that. What is observable is the reason it sits on the watch list: no named lab, nothing to verify. Being unverifiable is a reason for caution, not proof of fraud.
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.
Which UK peptide sellers do publish a verifiable certificate of analysis?
Of the 450 active UK sellers The Peptide Watch audits, 38 publish a certificate of analysis you can verify in their own name on the independent laboratory's own website. Ranked by most recent certificate, they are Lab77Peptides, Peptology Labs, Biovanta, Camo Chem, Biohackpeptides and 33 others. This is a record of who publishes verifiable paperwork, not a recommendation.
