Evolabs Research: 18 Kovera certificates.

None of the 18 certificates meets our failure rules: no lab fail, no unconfirmed identity, no purity under 95% and no content under 90% of the label. 12 measured more than 110% of the label, which Kovera does not grade as a fail.

Kovera revised 7 of these certificates after first publication, under the same report number: KVR-2026-EE331E (revised by the lab 2026-05-30: purity 99.788% → 99.731%, content 9.68 → 10.76 mg); KVR-2026-DF4A78 (revised by the lab 2026-05-30: purity 99.564% → 99.537%, content 52.25 → 53.81 mg); KVR-2026-AEC9DB (revised by the lab 2026-05-30: purity 98.552% → 99.528%, content 11.06 → 11.33 mg); KVR-2026-9F405D (revised by the lab 2026-05-30: purity 99.364% → 99.771%, content 5.19 → 5.67 mg); KVR-2026-129E57 (revised by the lab 2026-05-30: purity 99.629% → 99.402%, content 508.65 → 543.18 mg); KVR-2026-019FBF (revised by the lab 2026-05-30: purity 99.511% → 99.671%, content 11.38 → 5.59 mg); KVR-2026-83D3C6 (revised by the lab 2026-06-10: purity 98.977% → 98.98%, content 11.59 → — mg). Why that matters is in our revisions analysis.

A certificate covers the sample the client sent, and the client decides which results go public. The figures are as published on 2 August 2026; check the lab's verify page for the current version before you rely on one.
