In his new biography, Eric Gagne alleges that 80 percent of his teammates on the Dodgers were using performance-enhancing drugs.

Gagne admits that he used human growth hormone over five cycles in a three-year period toward the end of his career.

"It was sufficient to ruin my health, tarnish my reputation and throw a shadow over the extraordinary performances of my career," he says in the French-language book, titled "Game Over: The Story of Eric Gagne."

Gagne does not provide any names of players he says used PEDs.
