Lance Armstrong
At one point in time, Armstrong was considered an incredible cyclist and a true American hero. Unfortunately, this fame didn’t last. Rumors came that he’d used performance-enhancing drugs on more than one occasion. This would negate the tons of awards and physical accomplishments he’d achieved. Not only did he use steroids, but investigators accused him of also trafficking enhancement drugs. Armstrong used testosterone, cortisone, the human growth hormone, and an anti-diabetes drug the night before races. In a few moments, he was stripped of his seven Tour de France titles and flushed his career down the toilet (via The Guardian).
