In a television interview airing Friday on ABC's 20/20, Victor Conte, founder of Bay Area Laboratory Co-Operative (BALCO), said he supplied Jones with performance-enhancing drugs in the weeks leading up to the 2000 Sydney Olympics in which Jones won five medals.
"After I instructed her how to do it and dialed it up, she did the injection with me sitting right there next to her, right in front of me," he told ABC.
Conte claimed he gave her a substance called "the clear," later determined to be tetrahydrogestrinone (THG), the endurance-boosting drug EPO and insulin. He also showed her how to inject growth hormone into her leg.

Jones' lawyer, Richard Nicholls, vehemently denied the new allegations on Thursday.
"Marion has steadfastly maintained her position throughout: she has never, ever used performance-enhancing drugs," he said.
"Mr. Conte's statements have been wildly contradictory, while Marion Jones has steadfastly maintained her position throughout: She has never, ever used performance-enhancing drugs," said Nicholls. "Mr. Conte is simply not credible."
Conte is the subject of a grand jury investigation into steroid trafficking, allegedly providing banned substances to some of the world's biggest sports stars.
He faces charges in which BALCO is accused of concocting the designer steroid THG that, until recently, defied testing.
Jones has never failed a doping test, but Conte countered by saying no accurate tests existed for the substances he gave her during their 13-month working relationship.
The U.S. Anti-Doping Agency (USADA) is investigating Jones for alleged doping violations. In June, she passed a lie detector test arranged by her lawyers.
"We challenge him to submit to the same lie detector procedure that Marion Jones passed," Nichols said.
In July, Jones' former husband, C.J. Hunter, told federal investigators that the athlete was using banned performance-enhancing drugs during the 2000 Games. Insulin, THG and EPO were among the substances Hunter alleged that Jones used before, during and after the Olympics.
Track and field athletes charged with doping violations as a result of the BALCO investigation include Tim Montgomery, holder of the world record in the 100-metre sprint, Michelle Collins, Dwain Chambers, Chryste Gaines, Alvin Harrison, Kevin Toth and Kelli White.
Conte told ABC he designed a plan to use drugs to help Montgomery, the father of Jones's baby, break the world 100-metre record two years ago. Howard Jacobs, the sprinter's lawyer, refused comment.
Conte's lawyer, Robert Holley, could not be reached for comment.
