From the Vendor: Maeng Da Thai Red Vein Kratom originated in the jungles of Thailand but is now grown in several areas. The name literally translates to “pimp grade” kratom. The leaves of the tree have a characteristic network of red veins on the back of the leaves. All strains of Mitragyna speciosa kratom tree contain mitragynine, and the red-vein leaves have one of the higher concentrations of the alkaloid.
This is the not the cheaper “horned” material that other sites are selling as true RV Maeng Da and one of our most consistent products.
