Description
About Green Hulu
Green Hulu is a green-vein powder sourced from mature trees along the Kapuas River in the Hulu region of West Kalimantan, Borneo. The remote alluvial soils of the river basin produce leaf with a characteristic mid-range alkaloid profile.
Each lot is milled and packed by hand in Poughkeepsie, NY. The lab panel covers mitragynine, 7-OH-mitragynine, microbial limits, and heavy metals, with the full COA published by batch number.
Alkaloid Profile
The alkaloids most quantified for Green Hulu, measured by HPLC against the dry weight of the milled leaf. 7-Hydroxymitragynine is trace-level and naturally occurring, never concentrated.
Product Specifications
From Leaf to Mill
01 Hand Harvest
Mature leaves picked at peak vein-color expression by farmers we have worked with since 2019.

Five-day cure in humidity-controlled rooms. Never on the ground, never UV-bleached.
03 Fine Milling
The dried leaf is milled to a fine, even powder that suspends cleanly.
04 Lab Panel
Independent labs verify alkaloid ratios, heavy metals, salmonella, and total plate count.
