Hello! In monophasic (Logest, Mersilon, ZHanin, Diane-35 and many other things) preparations all tablets contain identical quantity or amount of hormones, that is within a month daily you accept identical tablets. Three-phase contraceptives (Trikvilar, Tri-regol, tri-mersi, triziston) have three types of tablets, thus imitating natural changes in an organism of the woman during a menstrual cycle.
