More reports means more evidence to inspect, not better quality. Each report counts once. Purity and amount percentages require at least five applicable results; explicit endotoxin failures are always shown. Missing measurements are not passes.
Understand the coverage
- Published COA report entries
- 121,194
- Ranked vendors across all seller groups
- 3,071
- Index refresh
Report dates are shown with each test. International classification does not establish factory ownership. U.S. resale does not establish U.S. manufacture.
The first 20 identities in each seller group’s original report-count ranking are shown to signed-in members. Changing the sort order does not change access. Vendors ranked 21 and below in those rankings remain named.
- International vendors
- 30 reviewed vendors · 7,735 unique reports · 20 observed in 30 days
- Compare manufacturers, exporters and other international sellers by their independent lab reports.
- Domestic resellers
- 102 reviewed vendors · 17,278 unique reports · 44 observed in 30 days
- Compare U.S.-based resellers. The seller is domestic; the product may still come from an overseas supplier.
- Seller type not reviewed
- 2,939 vendors · 57,178 unique reports · 353 observed in 30 days
- Sellers with independent lab reports whose seller type we have not reviewed yet.
Each report counts once, even when it tests several compounds or appears in multiple archives. Purity and dose results describe submitted samples, not everything a vendor sells. The methodology and known limitations explain eligibility and exclusions.
Explore recorded findings and compound comparisons
What is a domestic reseller?
A reseller buys from another supplier and sells under its own storefront or brand. Here, domestic means U.S.-based. Local shipping does not mean the product was made in the U.S. or tested after resale. Check the report for the actual batch.

Vendors with the most results that did not find the labeled compound.
What these counts include
All available results in the lab-findings comparisons. Each category counts only applicable tests; missing measurements do not count as passes. One sample can appear in several categories, but counts once in the overall total. These are counts of tested samples, not failure rates for everything a vendor sells.
International vendors: Recorded lab dates 2022-06-24 to 2026-10-27. 24 measured results have no usable date.
Domestic resellers: Recorded lab dates 2020-01-31 to 2026-10-27. 143 measured results have no usable date.
