Product Description
Norethisterone (NET), also known as norethindrone, is a medication that is used in combination with estrogen or alone in hormonal contraceptives, hormone replacement therapy, and in the treatment of gynecological disorders. It is a synthetic progestogen (or progestin) of the 19 nortestosterone group and has similar effects to those of natural progesterone, including suppression of gonadotropins, ovulation inhibition, and endometrial transformation. In addition to its progestogenic activity, NET also has weak androgenic and estrogenic effects at high dosages.
