Clomid or Clomiphene is a selective estrogen receptor modulator (SERM), it is very similar to another popular SERM, Nolvadex (Tamoxifen). Mostly Clomid is used for ovulation induction for infertile patients. Clomid has been used since the 1960’s, initially it was used by women with infrequent menstruation. In the middle of the 1970’s the drug became very popular as a strong fertility aid and it still continues being used with that goal today. The research has shown a great result among infertile women. Clomid is also one of the most used selective estrogen receptor modulators by androgenic anabolic steroid users. The drug is not an androgenic anabolic steroid but can be used to reduce estrogenic side effects that can be caused by using steroids. There are better drugs on the market to reduce estrogenic side effects such as Anastrozole, Proviron, etc.
