Andreas Krieger is one freak story. This person used to be a girl athlete but after taking steroids and other hormone injections to improve her athletic performance, turned into a man. Though It would not be fair to say though that he/she had control over her destiny because the communists ran the mass sports factories behind the wall.
Andreas Krieger, born as Heidi Krieger, was a former East German shot-putter, who competed as a woman in the East German athletics team. Like many prominent East German sportspeople at the time, Krieger was systematically doped with anabolic steroids.
People like those coaches should go to hell.
