Methenmadinone caproate (MMC, also known as superlutin caproate) is a progestin medication which was developed in Czechoslovakia in the 1960s and was studied for potential use in combined injectable contraceptives in the 1970s but was never marketed.^[1]^[2]^[3]^[4] It was studied as a combined injectable contraceptive in combination with estradiol valerate at doses of 60 mg and 10 mg, respectively, once a month by intramuscular injection (tentative brand name Lutofollin).^[2]^[3]^[4] MMC is the C17α caproate (hexanoate) ester of methenmadinone and an analogue of methenmadinone acetate (MMA; superlutin).^[5]^[6]^[1]^[7] In addition to MMA, analogues of MMC include chlormadinone caproate, gestonorone caproate, hydroxyprogesterone caproate, medroxyprogesterone caproate, and megestrol caproate.
