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 ),  nandrolone esters (most commonly nandrolone decanoate and nandrolone phenylpropionate ), stanozolol , and metandienone (methandrostenolone).  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 .  Dihydrotestosterone (DHT; androstanolone, stanolone) and its esters are also notable, although they are not widely used in medicine.  Boldenone undecylenate and trenbolone acetate are used in veterinary medicine . 
In November 1942, the Italian cyclist Fausto Coppi took "seven packets of amphetamine" to beat the world hour record on the track.  In 1960, the Danish rider Knud Enemark Jensen collapsed during the 100 km team time trial at the Olympic Games in Rome and died later in hospital. The autopsy showed he had taken amphetamine and another drug, Ronicol , which dilates the blood vessels. The chairman of the Dutch cycling federation, Piet van Dijk, said of Rome that "dope – whole cartloads – [were] used in such royal quantities." 
A quote from BFS, "[Out of all the people who take steroids, the fact is, x amount will suffer the harsh side effects]" It is a risk taken, knowingly, by those of us who choose to participate. Nobody is sticking anything in ourselves, but ourselves. I am sure if the % rate started to climb, the more people would rethink, but the fact remains is its that x % that suffer and the majority are fine. Now this doesn't mean that we should ignore this percentage, after all they are people, just like you and I and they share the same passion we all do and certainly we must not sit back and say "sorry bro, its gotta happen to someone." I really believe this "pushing the limit," in bodybuilding will eventually be its downfall. I was happy to see an earlier article on the return of "Classic Bodybuilding," guys weighing 200 and less, still big, still jacked, but not looking like the new hollywood Hulk. It was "is" about symmetry, proportion, muscularity. Not overall how big you are! A lot of changes need to taken and precautions to reverse this trend in BB that I believe can really help lower some of these tragic articles of our fellow brethren that we continue to get fed by the news. May bodybuilding and steroids live on! but only if we take a step back and look at what were really creating.
