Katsuya Kitamura, a Japanese wrestler, was banned for two years for violating the performance enhancing drugs ban. He was tested after a match and drostanolone was found in his system.
Used mostly by women fighting breast cancer, drostanolone was found to increase athletic muscle development and performance.
One website calls it:
Masteron has a deceivingly low anabolic/androgenic ratio, but since DHT is 5x as androgenic as testosterone and has a 3-4x higher affinity to receptor sites, Masteron provides a lot of “bang for the Buck” when examined on a Mg for Mg basis.
While another calls it:
Most users of Masteron are athletes and competitive body builders. The anti-estrogenic properties make it a very effective cutting agent. When Masteron becomes part of their regular cycle it gives the muscles a more defined look. Muscle lines will be more distinct since it has lower water retention.
For his part, Katsuya claims he became contaminated by the using supplements he bought internationally.
Most athletes will continue to claim innocence even when found guilty, so hopefully there is an appeals process he can follow.
