What we test
Before any concentrate leaves our hands, every batch is sent to a third-party, ISO-accredited lab for a full panel:
- Potency — confirms the exact mg of CBD per ml, so the measure-and-pour bottle is accurate.
- THC — verifies the product is below 0.3% THC (CBD isolate is THC-free/undetectable).
- Pesticides — screens for a broad panel of agricultural residues.
- Heavy metals — lead, arsenic, cadmium, and mercury.
- Residual solvents — ensures no processing solvents remain.
- Microbials — bacteria, yeast, and mold.
Status: the first production batch certificate of analysis (COA) will be published on this page the moment it returns from the lab. Every bottle ships with a QR code that links to its COA.
