Acne is often present. Acne conglobata is a particularly severe form of acne that can develop during steroid abuse or even after the drug has been discontinued. Infections are a common side effect of steroid abuse because of needle sharing and unsanitary techniques used when injecting the drugs into the skin. These are similar risks to IV drug abusers with increased potential to acquire blood-borne infections such as hepatitis and HIV/AIDS . Skin abscesses may occur at injection sites and may spread to other organs of the body. Endocarditis or an infection of the heart valves is not uncommon.
Since the benefits of exercise are virtually all hormonally mediated, it follows logically that manipulating levels of key hormones in the body can produce exaggerated responses to exercise. An example is the use of synthetic testosterone and growth hormone in athletes participating in sports that require a great deal of muscle mass, such as powerlifting, football and bodybuilding. On the other hand, the use of stimulants that mimic adrenalin, such as amphetamines, is prevalent in sports such as cycling and track, where muscle mass is not necessarily helpful or desirable, but the ability to maintain high levels of power output and energy expenditure is.
