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.
Because of an editing error, an article on Monday about teenage boys and body image misstated the number of boys who were interviewed as part of a recently published survey. It was 1,307, not 2,800. The article also misidentified the academic affiliation of a doctor who commented on supplements and steroids. The doctor, Shalender Bhasin, is a professor of medicine at Boston University School of Medicine and chief of endocrinology, diabetes and nutrition at Boston Medical Center. He is not a professor at Boston Medical Center. And the article misidentified the nationality of the soccer player Cristiano Ronaldo, whose body a teenager quoted in the article said he would like to emulate. Mr. Ronaldo is Portuguese, not Brazilian.
