Evidence

Assay library

Every certificate we hold, published before purchase rather than folded into the box afterwards. Where the issuing laboratory runs a public portal, each row links straight to its own record — so you are checking the lab, not us.

No certificate has been verified into the library yet.

This page counts what exists, not what we intend to have. It stays at zero until a real certificate with a named laboratory and a date is on file.

A published purity figure without a checkable certificate behind it is the exact thing this library exists to replace.
