How to verify a Horizon Analytical certificate

  1. Find the lot number or report number printed on the report (often under the QR code).
  2. Open the lab’s lookup: horizonanalytical.com/verify-coa 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 Horizon Analytical results count on PepAssure

Horizon Analytical certificates reach PepAssure as vendor uploads or from a public index. Once a member of our team has confirmed the purity figure from the document, each counts at half weight (0.5) in the Purity and CoA Verification pillars, and a vendor whose only evidence is this class is capped at 85. The vendor chose which batch to send, which is why it never carries the weight of a blind buy.

Vendors with the most Horizon Analytical results on file

A count is not a grade: it shows how much Horizon Analytical evidence we hold for each vendor. The results themselves, with dates and links to the lab’s copy, are on each vendor’s page.

Counts regenerate hourly. “Recognized” describes whether a report can be checked by anyone holding it, not the lab’s accreditation or accuracy. Wrong or missing information about this lab: corrections.
