We showed report number 6377.01.01 on this record; we misread it: 6377.01.01 is Vanguard Laboratory’s A2LA accreditation number, printed in the footer of its reports, not a report number; the certificate prints V260820-5 002.

PB
A COA is evidence, not a blanket safety guarantee. It describes the submitted sample and the panels reported in this document. It does not independently establish chain of custody, current inventory identity, or suitability for human use.
