Medroxyprogesterone (MP), is a progestin which is not used medically. A derivative, medroxyprogesterone acetate (MPA), is used as a medication in humans, and is far more widely known in comparison. Medroxyprogesterone is sometimes used as a synonym for medroxyprogesterone acetate, and what is almost always being referred to when the term is used is MPA and not medroxyprogesterone.
