Purity Peptides purity Peptides (a .clinic domain, but a research-peptide shop rather than a treatment clinic) sells tirzepatide, retatrutide, cagrilintide and other GLP-1 compounds with next-day UK delivery. It brands itself heavily as 'JANOSHIK VERIFIED', says 'every batch is independently analysed by Janoshik Laboratories', and claims '99.8%+ purity guaranteed', yet the same page states the certificate 'is on request', and no certificate, batch identifier or Janoshik verification link is actually published. Prominent lab branding with the evidence held back 'on request' cannot be independently verified. No company number is shown; contact is via [email protected].
| Fact | What we found | How it was checked |
|---|---|---|
| Standard applied | own-name verifiable-COA standard | how every vendor is judged, methodology |
| Certificate | nothing we could verify in this seller's own name, details below | read on the seller's own site |
| This audit as data | /data/vendor/purity-peptides-clinic.json | same record the open dataset serves, re-checked daily |
The Peptide Watch benchmarks every vendor on the same compound, BPC-157, the most common research peptide, as £ per milligram, so prices are directly comparable across all providers. No public BPC-157 price feed was available for this vendor at audit.
Purity Peptides (purity-peptides.clinic) 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.
You cannot independently verify its testing today. A good delivery reputation is not the same as a verifiable certificate; the two are unrelated. Until Purity Peptides publishes an own-name certificate you can check on an independent lab's website, you are taking its quality on trust.
The Peptide Watch does not assert that. What is observable is the reason it sits on the watch list: name-drops janoshik with nothing behind it. Being unverifiable is a reason for caution, not proof of fraud.
Not one that can be independently verified in its own name. ❌ Big 'Janoshik Verified' branding, certificate only 'on request'. Purity Peptides headlines 'Janoshik Verified' and '99.8%+ purity guaranteed', but its own page also states the certificate is 'on request', and no report
