Masteron or Drostanolone Propionate is a very unique anabolic steroid that has been derived from DHT. It was for long used as a treatment for breast cancer in post-menopausal women due to its strong anti-estrogenic properties.

This was also one of the reasons for its popularity, as a lot of bodybuilders would throw in Mast purely to control their E2 levels. And to avoid the need for a separate SERM. Despite having a low rating on both anabolic and androgenic scales, Masteron is a very versatile compound that can be added to both, bulking and cutting stacks. Most athletes and recreational bodybuilders these days are so hung up over building muscle mass that they tend to forget the importance of looking good while they gain muscle.
