steroidirunko

Steroidirunko is a Finnish term that translates to "steroid body" or "steroid physique." It refers to a body type developed through the use of anabolic-androgenic steroids (AAS). This physique is characterized by significant muscle hypertrophy, often appearing disproportionately large and heavily muscled, with a low body fat percentage. Individuals with a steroidirunko typically exhibit well-defined musculature, prominent vascularity, and a generally "hard" or dense appearance.

The development of a steroidirunko is a direct result of the anabolic effects of steroids, which enhance protein synthesis and nitrogen retention, leading to rapid muscle growth. This can also be accompanied by other physical changes, such as increased bone density and a potential reduction in body fat. However, the term also carries connotations related to the potential health risks and ethical considerations associated with steroid use. While the physique itself is a visible outcome, the underlying cause—steroid administration—is often implied and can be associated with a range of side effects, both physical and psychological. The term is commonly used in informal contexts, particularly within fitness and bodybuilding communities, to describe a specific aesthetic achieved through performance-enhancing drug use.
