Another 2007 study had similar findings, showing that, while 66% of individuals using anabolic steroids for non-medical purposes were willing to seek medical supervision for their steroid use, 58% lacked trust in their physicians, 92% felt that the medical community's knowledge of non-medical anabolic steroid use was lacking, and 99% felt that the public has an exaggerated view of the side-effects of anabolic steroid use.
Their use is referred to as doping and banned by most major sporting bodies.
For many years, AAS have been by far the most detected doping substances in IOC-accredited laboratories.
In countries where AAS are controlled substances, there is often a black market in which smuggled, clandestinely manufactured or even counterfeit drugs are sold to users.
The most commonly used anabolic steroids are testosterone (and its various esters, but most commonly testosterone propionate, testosterone enanthate, and testosterone cypionate), Others also available and used commonly but to a lesser extent include methyltestosterone, oxandrolone, mesterolone, and oxymetholone, as well as drostanolone, methenolone (methylandrostenolone), and fluoxymesterone.
Studies in the United States have shown that anabolic steroid users tend to be mostly middle-class heterosexual men with a median age of about 25 who are noncompetitive bodybuilders and non-athletes and use the drugs for cosmetic purposes.
"Among 12- to 17-year-old boys, use of steroids and similar drugs jumped 25 percent from 1999 to 2000, with 20 percent saying they use them for looks rather than sports, a study by insurer Blue Cross Blue Shield found."(Eisenhauer) Another study found that non-medical use of AAS among college students was at or less than 1%.According to a recent survey, 78.4% of steroid users were noncompetitive bodybuilders and non-athletes, while about 13% reported unsafe injection practices such as reusing needles, sharing needles, and sharing multidose vials, Another 2007 study found that 74% of non-medical anabolic steroid users had post-secondary degrees and more had completed college and fewer had failed to complete high school than is expected from the general populace.Anabolic steroid users tend to research the drugs they are taking more than other controlled-substance users; however, the major sources consulted by steroid users include friends, non-medical handbooks, internet-based forums, blogs, and fitness magazines, which can provide questionable or inaccurate information.are drugs that are structurally related to the cyclic steroid rings system and have similar effects to testosterone in the body.They increase protein within cells, especially in skeletal muscles.Anabolic steroids also have androgenic and virilizing properties, including the development and maintenance of masculine characteristics such as the growth of the vocal cords and body hair (secondary sexual characteristics).
