SAN FRANCISCO (AP) -- Barry Bonds juiced out of jealousy, Gary Sheffield followed his training buddy's lead and Jason Giambi did it to please his perfectionist father who loved the game, according to a new book. "Game of Shadows," which centers on Bonds' allegedly extensive drug regimen -- steroids, human growth hormone, insulin and more -- also undercuts Sheffield's claims that he took designer steroids unwittingly.

Sheffield has admitted that he used a cream two years ago but said he did not know it contained illegal steroids. The authors, however, say Bonds' trainer, Greg Anderson, put Sheffield on injectable testosterone and a human growth hormone in 2002, and later sold him designer steroids known as the "cream" and the "clear."


Sheffield adopted Bonds' heavy training program when he visited the San Francisco star after the 2001 season and lived in his home in Hillsborough, Calif., for two months, according to the book.

Though the two had a personal falling out, Sheffield wanted to maintain a relationship with Anderson so he could keep getting the drugs, the authors wrote.
On Wednesday in Tampa, Sheffield denied using any drugs mentioned in the book.
