Shelton and Rajfer (2012) noted that androgen deficiency in aging men is common, and the potential sequelae are numerous. In addition to low libido, erectile dysfunction, decreased bone density, depressed mood, and decline in cognition, studies suggest strong correlations between low testosterone, obesity, and the metabolic syndrome. Because causation and its directionality remain uncertain, the functional and cardiovascular risks associated with androgen deficiency have led to intense investigation of testosterone replacement therapy in older men. Although promising, evidence for definitive benefit or detriment is not conclusive, and treatment of LOH is complicated.
One last point: Because steroids have all these side effects, a lot of abusers will then take other drugs to offset the effect—steroid abuse causes you to grow man-boobs, so people take another drug to mitigate those side effects. Guys who take steroids often also take augmenting drugs to decrease estrogen production or to improve athletic performance even further, like human growth hormone, insulin-like growth factor 1, insulin, erythropoietin, stimulants, diuretics, levothyroxine, and/or gamma-hydroxybutyrate, according to the study in FP Essentials . That means on top of all these side effects of steroids, most abusers are also looking at a whole separate list of effects from their peripheral drug habits.
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.
