Charlie Sheen has admitted taking steroids to star as a baseball player in a movie.
The US star - who was fired from hit TV show Two And A Half Men following a public meltdown last year - told Playboy magazine that he took the performance-enhancing drugs for three months to help boost his pitching skills for 1989's Major League.
He said: "I wanted to put a little zip on my fastball. I didn't want to look like I was lily-arming it up there. I was always a hit-the-spots, low-zone pitcher. But my character, Ricky Vaughn, is a flamethrower. With steroids I went from a modest 78 mph to a decent 85, which on film can be made to look in the 90s."
But the 46-year-old confessed there was a downside.
He revealed: "I got injured a lot afterward. Steroids build your muscles, but they don't build your tendons or ligaments. Once you start altering your body's blueprint, things start falling apart. Some players take steroids, and two years later, after they've broken records, suddenly they have back problems, shoulder problems, arm problems. They're out of the game for good."
Charlie added that when you are using steroids "you're pissed all day long".
"About nothing," he added. "You just wake up and you're f*****g mad."
The Anger Management star continued: "But I had a trainer who was really smart. He'd been a defensive lineman in the National Football League. He knew enough guys who did steroids, and he knew enough doctors. I did steroids for only three months, and I never did them again. If there's a safe way to do steroids, we tried."
