QUALITY & TESTING

COA · Certificate of Analysis

Un certificado de análisis (COA) es un informe de laboratorio independiente que verifica qué contiene, y qué no, un producto. En el caso del CBD, confirma la potencia de los cannabinoides (incluido el THC) y detecta contaminantes como metales pesados, pesticidas y microbios.

Cómo leer un COA

Un laboratorio acreditado (ISO/IEC 17025) y un número de lote que puedas hacer coincidir con tu compra son las dos señales de un COA fiable. Cada lote de Mery J publica el suyo.

Why it matters

The COA is the single most important trust document in CBD. It turns marketing claims into verifiable facts, which is why we publish one for every batch.
