Pinealon has 71 independent tests on file from 12 laboratories across 48 vendors; the recency-weighted purity index is 99.54. The most recent test was submitted on 2026-08-03.
These are certificates shops have chosen to publish, verified for authenticity before listing. Because shops decide which COAs to make public, the set reflects the batches they published rather than every production batch — a selection bias we state openly. How the index is calculated →
