Each user experiences their own unique feelings when using steroids and coming off the drug. When someone chooses to stop using they can experience a variety of withdrawal symptoms linked to addiction. Symptoms can include mood swings, fatigue, restlessness, loss of appetite, insomnia, reduced sex drive, the desire to take more steroids, and depression. Evidence for steroid addiction is certainly not as strong as it is for other drugs like cocaine or heroin. Though it is clear that people develop a tolerance and dependence on them and willingly experience negative consequences when using steroids - both of which are signs for drug dependence.
There are lots of different types of anabolic steroids , but most of them beefify similarly. When we work out, we create tiny micro-tears in muscle fibers. When the muscle regrows and heals, it grows back a little bit larger, and repeating that process over time is how we get hard and massive (that's the idea anyway). The male sex hormone testosterone facilitates that muscle growth. Anabolic steroids do the same thing but better and faster. They also speed the muscle-healing process by blocking the stress hormone cortisol, which breaks down muscle tissue. That can mean less down time for athletes who go into overtime.
