What we found
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].

Questions people ask about Purity Peptides
Is Purity Peptides legit?
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.
Does Purity Peptides publish a real, verifiable Certificate of Analysis?
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, batch number or verification link is published.
How do I check Purity Peptides's certificate myself?
Find the certificate on purity-peptides.clinic and read four things: an independent laboratory is named; the client field names Purity Peptides, 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.
