Dianabol is the old Ciba brand name for the oral steroid methandrostenolone. It is a derivative of testosterone, exhibiting strong anabolic and moderate androgenic properties. This compound was first made available in 1960, and it quickly became the most favored and widely used anabolic steroid in all forms of athletics. This is likely due to the fact that it is both easy to use and extremely effective. It remains the most commonly used black market oral steroid in the U.S. As long as there are countries manufacturing this steroid, it will probably remain so.
Similar to testosterone and Anadrol 50®, Dianabol is a potent steroid, but also one which brings about noticeable side effects. For starters methandrostenolone is quite estrogenic. Gynecomastia is likewise often a concern during treatment, and may present itself quite early into a cycle (particularly when higher doses are used). At the same time water retention can become a pronounced problem, causing a notable loss of muscle definition as both subcutaneous water and fat build. Sensitive individuals may therefore want to keep the estrogen under control with the addition of an antiestrogen such as Nolvadex® and/or Proviron®. The stronger drug Arimidex® (antiaromatase) would be a better choice, but can also be quite expensive in comparison to standard estrogen maintenance therapies.
