Clomid (Clomiphene Citrate) is a powerfully effective anti-estrogen officially classified as a Selective Estrogen Receptor Modulator (SERM). In many ways, it is very similar to another popular SERM in Nolvadex (Tamoxifen Citrate). Clomid first gained worldwide attention in the early 1970’s as a strong fertility aid and is still used for that purpose today. It is also one of the most commonly used SERM’s by anabolic steroid users. No, it is not an anabolic steroid but can be used to combat estrogenic side effects sometimes caused by anabolic steroids. It can also be used as a Post Cycle Therapy (PCT) medication in order to stimulate suppressed testosterone production due to anabolic steroid use. PCT use of Clomid is the most common purpose and most beneficial point of use for the anabolic steroid user.
