How we rank
A precomputed daily snapshot, not a live search. Only lab results that carry a verifiable third-party certificate are eligible, so every entry can be independently checked. Unverified community and messaging-app uploads never rank.
- Tier 1 Severe. A failed endotoxin test, or a lab result that detected a different compound than the label claims.
- Tier 2 Underfill. The delivered dose measured 40% or more below the labeled amount.
- Tier 3 Low purity. Everything else rankable, ordered by the lowest measured purity.
Named vendors are listed first, and at most two results per vendor appear, so a single bad batch cannot dominate the list. Follow any verify link to check the certificate with the issuing lab.
