And blood pressure problems, according to Yesalis, have been exaggerated. no2 nitric oxide steroids Steroids. There is some associative evidence that steroid use can increase the risk of prostate cancer, but this link has yet to be borne out in a laboratory setting. No studies of any kind link the use of anabolics to testicular cancer. Addiction is a legitimate concern, and Yesalis says a quarter to a half of those who use steroids solely to improve their body image exhibit signs of psychological dependence. no2 nitric oxide steroids Muscle pictures. "But in all my years of research," Yesalis continues, "I've only known three professional athletes who were clinically addicted to steroids. " The distinction, he explains, is that professional athletes see steroids as little more than a tool to help them do their job -- the way "an office worker views his computer. " Once their playing days are over, almost all the athletes within Yesalis' purview "terminate their use of the drug. no2 nitric oxide steroids Steroid abuse photos. "One reason the health effects of steroids are so uncertain is a dearth of research. In the almost 65 years that anabolic steroids have been in our midst, there has not been a single epidemiological study of the effects of long-term use. Instead, Yesalis explains, concerns about extended usage are extrapolated from what's known about short-term effects. The problem is that those short-term research projects are often case studies, which Yesalis calls the "lowest life form of scientific studies. " Case studies often draw conclusions from a single test subject and are especially prone to correlative errors. "We've had thousands upon thousands [of long-term studies] done on tobacco, cocaine, you name it," Yesalis complains. "But for as much as you see and hear about anabolic steroids, they haven't even taken that step. "What about the research that has been done? At least some of it seems to yield engineered results. "The studies linking steroid use to cancer were performed by and large on geriatric patients," notes Rick Collins, attorney, former bodybuilder, and author of the book Legal Muscle, which offers an exhaustive look at anabolic steroid use under U. S. law. The hazard of such research is that side effects observed in an older patient could be the result of any number of physiological problems unrelated to steroid intake. Moreover, the elderly body is probably more susceptible to adverse reactions than the body of a competitive athlete. Collins believes that some studies were performed with a conclusion in mind at the outset. "Their hearts were in the right place," says Collins. "Curtailing nonessential steroid use is a good and noble goal, but they undermined their efforts by exaggerating the dangers. " Call it the cry-wolf effect. For instance, it's long been dogma that use of anabolic steroids interferes with proper hepatic (liver) function and causes thickening of the heart muscle. However, a 1999 study at the University of North Texas found that it's not steroid use that causes these medical phenomena; rather, it's intense resistance training. Weight-lifting causes tissue damage, and, at high extremes, can elevate liver counts and thicken the left ventricular wall of the heart.
