According to Hunter's 2004 testimony before a federal grand jury, Jones's use of banned drugs began well before Sydney.  Hunter told the investigators that Jones first obtained EPO (Erythropoietin) from Graham, who Hunter said had a Mexican connection for the drug. Later, Hunter said, Graham met Conte, who began providing the coach with BALCO "nutritional supplements", which were actually an experimental class of "designer" steroids said to be undetectable by any drug screening procedures available at the time. Graham then distributed the performance enhancers to Jones and other Sprint Capitol athletes. Still later, Hunter told federal agents, Jones began receiving drugs directly from Conte.
Telmisartan has been used by endurance athletes as an alternative to the banned substances AICAR and GW1516. It is also a relatively safe and non-toxic drug used by athletes in dosages of 80-160 mg/day in divided dosages. The latter two drugs have been banned. Telmisartan has been shown to act by a similar mechanism. Specifically, telmisartan promises to enhance running ability, increase fat burning ability, reduce lactic acid formation and enhance recovery from exercise. However, its actual performance-enhancing effects remain the subject of debate.
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.
