D Bol 10 is an oral steroid which contains 10 mg of the hormone Methandienone. It is a derivative of testosterone, exhibiting strong anabolic and moderate androgenic properties. D Bol 10 is a potent steroid, but also one which brings about noticeable side effects, such as gynecomastia and water retention. Sensitive individuals may therefore want to keep the estrogen under control with the addition of an anti-estrogen such as Nolvadex and/or Proviron. The stronger drugs Arimidex, Femara, or Aromasin (antiaromatase) would be a better choice if available.
