A new 50-minute investigatory report on sports doping from Al Jazeera America, "The Dark Side," released on Dec. 26, is tearing its way through the Internet today. The report shines a light on the world of performance-enhancing drugs in a way not seen since Alex Rodriguez and 13 other MLB stars were suspended in 2013 for getting hormones from the Biogenesis clinic in Miami. This new investigation spent months following British track athlete Liam Collins as he travels from the Caribbean to Vancouver to Indiana, telling doctors he wants one last chance at the Olympics in 2016—all while secretly recording his interactions.
