Description
About Green Jongkong
Green Jongkong is a green-vein Mitragyna speciosa powder grown in the Jongkong district of West Kalimantan, Indonesia. The leaf is harvested at mid-maturity from mature trees and dried indoors before milling to a uniform fine grind.
Each lot is packed by hand in Poughkeepsie, NY, third-party tested, and listed on our COA dashboard by batch number.
Alkaloid Profile
The alkaloids most quantified for Green Jongkong, measured by HPLC against the dry weight of the milled leaf. 7-Hydroxymitragynine is trace-level and naturally occurring, never concentrated.
