The release of documents from the Bay Area Laboratory Co-operative reveal the extent of drug use by disgraced track star Marion Jones, according to a report on ESPN.com.

The ledger, whose existence was long known, has the names of several other athletes redacted, but the documents essentially suggest the extent of doping by BALCO clients.

The ledger and accompanying calendars document Jones' use of the steroids norbolethone and tetrahydrogestrinone (THG), as well as the oxygen-boosting drug EPO, human growth hormone and insulin. The documents indicate her use of the substances in 2000 and 2001.

The Web site likens the entries to "logging profits and losses," and says BALCO kept a several-page document that listed names of athletes, doses of the performance-enhancing drugs they took and results of urine tests conducted to detect steroids and masking agents.

The records were made public as part of the government's case against Jones, who has pleaded guilty to two counts of making false statements to federal agents. She is scheduled to be sentenced Jan. 11.

Jones won five medals, including three golds, at the 2000 Sydney Olympics. The ledger specifically indicates she used performance-enhancing drugs in the month immediately before the Olympics began, and during the Games.

On Oct. 5, Jones pleaded guilty to one count of lying to investigators about her drug use when she told them in a Nov. 4, 2003, interview that she had never taken the banned drugs, never even seen or ingested the drug in the case known as "the clear," and never received any of those substances from track coach Trevor Graham.

Graham is under indictment for making false statements. He has pleaded not guilty, and his case is pending. *
