These are the market-level figures from The Peptide Watch's ongoing audit of every identifiable UK research-peptide seller. Each is a single number with the date it was measured, computed from the same daily audit that powers the directory.
📊 As of 10 July 2026, of 318 active UK research-peptide sellers audited by The Peptide Watch, 28 (9%) publish their own verifiable Janoshik certificate of analysis.
📊 290 of the 318 active sellers (91%) publish no certificate that can be verified in their own name.
📊 The Peptide Watch has audited 420 UK research-peptide domains in total: 318 active retailers, 59 dead or parked, and 43 out of scope.
📊 Every verified certificate in this audit was issued by a laboratory outside the UK (Janoshik in Prague, or Analiza in Poland); no UK laboratory issued a single verified report.
📊 12 clusters of separately-branded UK shops trace back to a single shared operator, so some apparent competitors are the same seller.
A seller passes only when it publishes an own-name Janoshik certificate of analysis that can be verified on Janoshik's own website. "9%" is 28 of the 318 active retailers; the wider figure of 420 is every domain ever audited, including 59 that are now dead and 43 out of scope. One definition, stated once.
