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].
See the full audit. This is the short answer; the full Purity Peptides dossier has the certificate check with a live verification link, the Companies House record, pricing against the market and the complete checklist.
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
