A-Rod, Lance Armstrong, Jose Canseco, Rashard Lewis, Shawne Merriman. The list of superstar athletes accused of -- or admitting to -- taking performance-enhancing drugs is almost as impressive as the number of sports in which they compete. It's not just weightlifting, baseball and cycling. It's football, track and field, swimming, soccer and basketball . And it's not restricted to males -- or to professionals. Just ask former Olympic track star Marion Jones. Or the nine high school athletes in Texas caught using performance-enhancing drugs during the 2011-2012 academic year.

The most commonly used AAS in medicine are testosterone and its various esters (but most commonly testosterone undecanoate , testosterone enanthate , testosterone cypionate , and testosterone propionate ), [53] nandrolone esters (most commonly nandrolone decanoate and nandrolone phenylpropionate ), stanozolol , and metandienone (methandrostenolone). [1] Others also available and used commonly but to a lesser extent include methyltestosterone , oxandrolone , mesterolone , and oxymetholone , as well as drostanolone propionate , metenolone (methylandrostenolone), and fluoxymesterone . [1] Dihydrotestosterone (DHT; androstanolone, stanolone) and its esters are also notable, although they are not widely used in medicine. [54] Boldenone undecylenate and trenbolone acetate are used in veterinary medicine . [1]
