Montgomery has not failed a drugs test but can be banned for "non-analytical positives", the term for evidence that he used drugs.
In his testimony on 6 November last year, published by the San Francisco Chronicle yesterday, Montgomery admitted he took THG and Human Growth Hormone provided by Conte, although he was not using them when he set the world record with 9.78sec in 2002.
The sprinter testified that Conte had given him weekly doses over an eight-month period ending in 2001.
When Montgomery met Conte at the Sydney Olympics, the Balco founder produced a sample of THG and was told it was unidentifiable in normal drug testing.
Montgomery's response was: "This was the magic potion."
Britain's own European 100m champion, Dwain Chambers, was found guilty of using THG. He is serving a two-year ban.
Meanwhile, Scottish cyclist David Millar has been released by French police after being held for questioning as part of a doping investigation into his Cofidis team.
Millar, due to ride next month's Tour de France, has never failed a drugs test and denies all doping accusations.
