Sumatran white vein. The morning end of the shelf.
White vein is harvested earliest in the leaf cycle, before the stem and vein darken. It is the least processed point on the same plant.
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.
