Many steroids can convert to estrogen in the process of aromatisation and can lead to gynecomastia and excess water retention. Clomid prevents estrogen binding to its receptors to reduce the risk of side effects. It is very helpful to fight and prevent gynecomastia and to lower the level of retained water. In a Post Cycle Therapy plan, Clomid helps to restore a natural level of testosterone and is very commonly used by bodybuilders as part of a PCT plan. Clomid is the best product on the market and an excellent SERM that comes highly recommended. Most users recover completely in 2 weeks.
