Accreditation
The pages of horizonanalytical.com read on October 21, 2026 (home, about, Verify COA) state no laboratory accreditation.
How verification works
Horizon’s Verify COA page searches by report number (required) and lot number (optional). Prof. Peptide’s matches used the public certificate search behind that page, after a made-up report number returned no certificates (October 18, 2026).
A match confirms the record is Horizon’s own, including the client name it holds; it does not confirm chain of custody between the tested sample and a specific vial.

3 certificates from 1 vendor, each found at Horizon Analytical’s own lookup after that lookup refused an invented code, and counted by the same rule as the vendor’s verification panel.

Limitations
- Prof. Peptide checks certificates through the same public lookup a reader would use, and has not visited the laboratory or observed testing directly.
