I do not condone steroid use by teenagers. At the same time, I think it has been wildly exaggerated as to how many high-school students are into steroids. I have seen statistics as low as 3% and as high as 20%. That’s a pretty big range, which makes it tough to believe we even have anything like an accurate idea of what the percentage really is. But that’s not really important. If I was a parent, and I do happen to have a son and a daughter myself, I would be far more concerned with Junior drinking alcohol, smoking marijuana, taking Ecstasy, or snorting cocaine. I watch the news and read the papers, and I never seem to read about fatal car accidents or drug overdoses involving teenagers and steroids. Nobody is slipping a couple tablets of Winstrol into a 16-year-old girl’s drink and committing a date rape. Teens have no business using steroids, but as far as being a threat, there are about a hundred other drugs far worse to worry about. Any time you hear differently you can be sure it’s a slow news day down at Channel Five.
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 .
