Every batch is third-party tested before it ships, and the lot number on your bag matches the certificate of analysis exactly. If a batch has no COA in hand, it does not ship.
Every published batch is screened by a third-party lab for alkaloid content (mitragynine and 7-hydroxymitragynine), heavy metals, and microbial contamination. A certificate of analysis covers the lot it names and no other lot. A batch without one in hand does not ship.
