Open review queue →This label reflects how the provider presents itself on its own site today, not a formal accreditation category.
Whether the site appears to invite direct sample submission from individuals rather than only business or institutional clients.
Whether the provider appears to offer public-facing report publishing, result browsing, or direct verification tooling.
This is our shorthand for how visible the provider's result or verification layer appears to be, ranging from none to searchable public verification.
Location details are kept conservative and only shown when clearly supported by the source page or the provider’s public materials.
What we can verify now
Horizon Analytical is an analytical testing lab that vendors reference on their
public COAs with the line “Searchable via: horizonanalytical.com”. Each report
prints a lot number (e.g. BP-3713888-P) that a reader can enter on the lab’s
own public verification page at /verify-coa — so the certificate can be checked
against the testing lab, not just the vendor.
Its own site advertises, in the lab’s words, “certificates your customers can verify” alongside HPLC/MS purity, chemical identity, quantitation, and endotoxin panels with a stated 48–72h turnaround.
Why it matters in the current vendor graph
Horizon is the third-party lab behind a chunk of Blank Peptides’ per-lot purity COAs, sitting next to Freedom Diagnostics in that vendor’s archive. It counts as a genuine provider-public-lookup surface: the lot code resolves on the lab’s own domain, which is materially stronger than a purity number printed on a vendor-controlled page.
What to watch for
The verification page is a client-rendered lookup (the lot code isn’t a deep-linkable URL), so PeptideBenchmark links the public verify surface and carries the lot code rather than a one-click deep link. Treat a Horizon lot code as verifiable at the lab, and enter it on the lab’s verify page to confirm.
