What psychological effects might steroid users experience, specifically relating to aggression?

Increased aggression is a well-documented psychological effect experienced by steroid users. Anabolic steroids, which are synthetic derivatives of testosterone, can lead to a range of mood changes known as "roid rage." This term describes episodes of aggressive behavior that are intensified by the use of steroids. The biochemical changes that occur in the brain due to elevated testosterone levels can disrupt normal mood regulation, contributing to heightened irritability and increased aggression.

Those who use steroids may find that they react more explosively to stressors that would ordinarily provoke a lesser response. This aggression can manifest in various ways, including verbal outbursts, physical altercations, or other confrontational behaviors.

The other options present conditions that are generally contrary to the effects observed in steroid users. Heightened calmness, decreased confrontational behavior, and lowered anxiety levels do not align with the evidence that suggests steroids can heighten aggressive tendencies and irritability. Thus, the association of increased aggression with steroid use is supported by both empirical research and anecdotal reports within the fitness and medical communities.
