Methodology

On October 19, 2026 we fetched each vendor's public homepage and any linked COA, quality or test-results page at about one request per second, respecting robots.txt, without logging in or buying anything. We recorded whether each item appeared on the vendor's own pages and kept the source URL for each fact (shown on each vendor profile).

3 vendor sites blocked automated access (HTTP 403) and are excluded rather than described from other sources. We did not test any product; vendor statements are vendor statements.
