O.P.M.s. Liquid Kratom Extract is manufactured using the high-pressure and cold-water extraction. This process allows the kratom to preserve 95% of the active alkaloids which is higher than any other known extraction process to. To make liquid Kratom, we deviate from the regular process at the point where the concentrated extract would normally be dried. Instead it is pre-treated with natural preservatives and bottled fresh off the process line. Our O.P.M.s. Liquid Kratom is derived from the same superb quality Maeng Da Kratom that is used in all of our Kratom products.Each bottle contains 8 mL of liquid Kratom with 12 grams of Maeng Da Kratom extract no alcohol added.
