How to read a COA

Match the batch number on your bottle to the batch in the table above — that is the only result that applies to your bottle.

Check the test date — a recent test date means the result is for a current batch, not an old one.

Check the lab’s name — every Antidote batch on this page was tested by an independent third-party lab, not in-house.

Check the per-serving numbers — for kratom, that is mitragynine per serving; for Nano Kava, that is total kavalactones.

Check heavy metals and microbes — on an Antidote COA these results are shown as numbers below the lab’s limits.
