Field notes
The homepage says it tracks 15 active vendors and that 8 publish lot-matched COAs; its tables report 223 normalized prices per milligram and 13 enforcement events, checked October 21, 2026. Its ranking rubric names COA transparency, independent tests, regulatory record, and policy clarity, while the COA guide distinguishes purity testing from identity testing. These are the site's reported coverage and criteria, not evidence that any listed product is safe or effective.
