Our Green Borneo Kratom capsules contain ultra-fine ground powder, sourced from the mature leaves of the Mitragyna Speciosa tree in the dense forests of Borneo. The capsule form provides researchers with a standardized sample amount per unit, which is crucial for reproducible results in microscopic and alkaloid analysis. The shell protects the botanical material from oxidation and moisture, ensuring the integrity of the diverse alkaloid profile is maintained. Perfect for laboratories that prioritize precision and ease of use.
