Anabolic steroids affect a part of the brain called the limbic system, which controls mood. They don’t cause a “high” like some other drugs, but can cause harmful effects.
Long-term steroid misuse can lead to aggressive behavior and extreme mood swings. This is sometimes referred to as “roid rage.” It can also lead to feeling paranoid (like someone or something is out to get you), jealous, delusional (believing in something that is not true), and invincible (like nothing can hurt you).
