Empower pharmacy also spelled estradiol enanthate and sold under the brand names Perlutal and Topasel, among others, is an estrogen medication which is used in hormonal birth control for women. I planned it in combination with dihydroxy progesterone acetophenide (DHPA; algestone acetophenide), a progestin, and is used specifically as a combined injectable contraceptive. Estradiol enanthate is not available for medical use alone.
