We marked this certificate as disappeared on Sep 14, 2026. That was our error: our capture that day read only the gallery each product page shows by default, so we had no basis for the claim. On Sep 29, 2026 we found this image in the gallery of another variation of the same product (visible to signed-in customers), a variation Atomik Labz already offered on Sep 14, 2026, whose gallery we had not observed. We withdraw the claim. It is listed as current again.
As originally recorded: last seen Sep 12, 2026 · marked disappeared Sep 14, 2026 · listed again Sep 30, 2026. Correction · Oct 8, 2026
We showed laboratory Janoshik Analytical on this record; we misread it: the certificate prints Vanguard Laboratory. 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 V250813-25 007.

PRODUCT RELATIONSHIP Exact catalog attribution The vendor and normalized product URL match the tracked catalog exactly. Name-only similarities are never promoted to this state.
02 / PANEL COVERAGE
Panel evidence and provenance Lab-verified and document-extracted panels count as certificate coverage. Vendor-stated panels remain visible, but are not represented as results from this document.

No provider lookup attached Vanguard Laboratory
This record currently relies on the vendor-hosted certificate and PB’s preserved copy. That is a weaker verification surface than a lab-controlled lookup.

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.
