O.P.M.S. tests all Kratom for heavy metals, feces, and mold content. O.P.M.S. filters the Kratom to remove any foreign objects. O.P.M.S. has developed a unique process of pulverizing its Kratom powder to a very fine powder. This process allows more surface area for the Kratom powder, making it much more desirable. It also allows O.P.M.S. to compact more powder into a smaller capsule.
