Clomos is a brand name for clomiphene citrate. It is typically prescribed for women to aid in ovulation. In men, the application causes an elevation of follicle stimulating hormone and luteinizing hormone. As a result, natural testosterone production is also increased. This effect is obviously beneficial to the athlete, especially at the conclusion of a cycle when endogenous testosterone levels are subnormal. When an athlete discontinues the use of steroids, his testosterone levels will most likely be suppressed. If endogenous testosterone levels are not brought to normal, a dramatic loss in size and strength may occur. Clomos plays a crucial role in preventing this crash in athletic performance. Bodybuilders find that a daily intake of 50-100 mg of clomiphene citrate over a two week period will bring endogenous testosterone production back to an acceptable level. It will gradually raise testosterone levels over its period of intake. Clomos is also effective as an anti-estrogen.
