Testosterone is a well-known hormone and anabolic steroid that plays a crucial role in the development and maintenance of male characteristics. While naturally occurring in men and women, it is predominantly associated with male health and development. Beyond its natural occurrence, synthetic testosterone is used for various medical and non-medical purposes. This article provides a comprehensive overview of anabolic steroid testosterone, its uses, benefits, side effects, and legal status.

Testosterone is the primary male sex hormone and an anabolic steroid. It is responsible for the development of male reproductive tissues, such as the testes and prostate, as well as promoting secondary sexual characteristics like increased muscle and bone mass, and the growth of body hair. In medical contexts, synthetic testosterone is used to treat several conditions related to low testosterone levels. (Source)
