Clomifene is sold under the brand name Clomid and is used among athletes and bodybuilders to increase testosterone levels, hormones that cause follicle stimulation, and better production of GnRH. After their steroid therapy, athletes need to get their hormones back in balance by taking supplements but this is of no use. Clomid is used in such a situation since it affects the level of LH and FSH directly. Both LH and FSH affect the production of testosterone. Clomifene is attached to the estrogen receptors and regulates their activity increasing testosterone after a period of time.
