Steroids are found naturally in both animals and humans, but in daily talk the term is used about synthetically produced glucocorticosteroids and anabolic steroids.

Anabolic steroids add muscle mass and are perhaps best known from the world of sports where they are used as a form of doping.

Anabolic steroids are prohibited, not only because they are performance enhancers and therefore distort the competition, but also because they can have severe consequences for users, both psychological and physical, and in some cases life threatening ones.

Keynotes about steroids look into the topic of anabolic steroids and their frequent but illegal use in the world of sports.
