Four factors. One score. No exceptions.

Every vendor starts at zero. Points are added only for documented, verifiable behavior. A payment to us doesn't exist in the formula. A removal of documentation costs points immediately, regardless of prior standing.

40%

COA Depth & Traceability

Third-party lab certificates present, dated, and linked to specific lot numbers. In-house-only testing earns partial credit. No public COA means the vendor cannot score above 30.

25%

Claims Risk Screen

All product pages reviewed for human-use language, dosing language, and treatment claims. Each open flag reduces the score. Resolved flags recover points within one week.

20%

Regulatory History

FDA warning letters, import alerts, and import refusals on record. Each active citation reduces the maximum achievable score. We check the FDA's public databases weekly.

15%

Support & Transparency

Response time to documentation requests, refund policy clarity, and shipping transparency. Tested via blind inquiry once per quarter per vendor.

Independent laboratory testing underpins every score. We do not accept vendor-supplied results as primary evidence.
