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 . 
We are becoming quite tired of these senseless and premature steroid deaths. Nasser’s death immediately followed the death of Matt Duval. Matt Duval was another bodybuilder with too much body weight relative to his vertically-challenged frame. Unlike Nasser, Matt didn’t achieve the same level of notoriety with competitions limited to amateur Junior National competitions and ad hoc guest posing appearances. We offer no kind words to describe either Matt Duval or Nasser El Sonbaty following such horrible deaths. In his absence, Nasser adversely affected the lives of family members, American & German friends, and a global fan base. The enormity of their structures was influential to young generations determined to initiate steroid cycles even though they would become too addicted to observe Nasser’s final outcome and deviate from their destructive behavior. For these reasons, we offer no ‘Rest In Peace’ sentiments. Rather, we say “It Is What It Is”.
