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.
