This is the first available supplement which includes butein chalcones. These substances, according to Y. Wang’s newest research (Department of Biochemistry, The Chinese University of Hong Kong, Rm. 507C MMW Bldg., Shatin, N.T., Hongkong) can reduce aromatase by 90%, thus by much more than synthetic inhibitors (Arimidex, mesterolon). Research is currently being conducted concerning the use of butein in the treatment of neoplasm linked with estrogen, but the substance is still unavailable for athletes taking part in competitive sports. Henryk Różański, MD., has been conducting studies on pharmaceuticals of this type, and has elaborated a product that may be used as a supplement by athletes. None of its substances is tested for in anti-doping tests, and its use does not hinder the hypothalamic–pituitary axis.
