The product page claims third-party lab testing and a COA is available, and the lab-reports page lists a KPV batch (RB-KPV-2709) with 99.79% purity and a test date of 2026-02-17. I could not access an actual COA/report document in this session, so there is no verified lab document or chromatogram to score beyond the supplier’s listed batch table.
