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 . 
Anemia is a medical condition that is characterized by a low red blood cell count. These cells are responsible for transporting oxygen to every part of the body and take back carbon dioxide to the lungs for removal. Since oxygen is the fuel needed to burn glucose and other nutrients to produce the energy needed by the body, a low RBC count means that your body will be weaker than it should be. Furthermore, you will not be able to engage in any strenuous activities, such as running or jogging because your RBC cannot supply enough oxygen to meet the body’s energy needs. Doctors normally prescribe anabolic steroids to help increase the RBC count of anemic patients, thereby treating the illness. However, continued use of steroids will be required.

There are lots of different types of anabolic steroids , but most of them beefify similarly. When we work out, we create tiny micro-tears in muscle fibers. When the muscle regrows and heals, it grows back a little bit larger, and repeating that process over time is how we get hard and massive (that's the idea anyway). The male sex hormone testosterone facilitates that muscle growth. Anabolic steroids do the same thing but better and faster. They also speed the muscle-healing process by blocking the stress hormone cortisol, which breaks down muscle tissue. That can mean less down time for athletes who go into overtime.
