Steroids can make pimples pop up and hair fall out. They can make guys grow breasts and girls grow beards. Steroids can cause livers to grow tumors and hearts to clog up. They can even send users on violent, angry rampages. In other words, steroids throw a body way out of whack. Steroids do make users bulk up, but the health risks are high. It's true, on steroids biceps bulge; abs ripple; and quads balloon. But that's just on the outside. Steroid users may be very pleased when they flex in the mirror, but they may create problems on the inside. These problems may hurt them the rest of their lives. As a matter of fact steroid use can shorten their lives.
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.
