How to verify a Janoshik certificate

  1. Find the task number + unique key printed on the report (often under the QR code).
  2. Open the lab’s lookup: janoshik.com/verify and enter it.
  3. Compare the lab’s copy with the one you hold: compound, lot, date, purity. Any difference means the document you were given is not the lab’s.

A match confirms the certificate is genuine. It does not prove that the vial in your hand came from the tested sample — only blind-buy testing does that. You can also run the check through our COA checker.

How Janoshik results count on PepAssure

Results read from Janoshik’s own public index are blind-tested — the vendor did not choose the sample — and carry full weight (1) in the Purity and CoA Verification pillars. A Janoshik certificate that a vendor uploads is a different thing: it is a vendor-selected sample and counts at half weight.
