Stacked: Inside the Enhancement Craze

CNN International Correspondent Isobel Yeung premieres an examination of the growing mainstream appeal of performance-enhancing drugs.Performance-enhancing drugs have long been one of sports' greatest taboos. Today, "enhancement" has evolved far beyond elite competition into a booming industry backed by billionaire investors, fueled by social media algorithms, and marketed to young men as the path to greater strength, confidence, and success. In this hour, Yeung travels from Texas to Abu Dhabi and Las Vegas to investigate the forces driving the enhancement economy, including reporting from inside the Enhanced Games, an Olympic-style competition that encourages athletes to use performance-enhancing drugs."We spent months deep inside the male enhancement boom, and it has been shocking to see how far people are willing to go for a better-looking or better-performing body,' Yeung said. "The momentum is huge – and it's all over social media – so we wanted to sit down with the powerful players behind this boom and the young men who are buying into it, and ultimately paying the cost."Along the way, Yeung meets influencers promoting testosterone, steroids and peptides, and speaks with athletes embracing the movement, including Olympic gold medalist sprinter Shania Collins and Olympic gold medalist swimmer Cody Miller. Amid growing calls to loosen access to testosterone, she also interviews medical experts who warn of the potential health risks associated with misuse, and sits down with author and podcast host Scott Galloway to consider how testosterone therapy has become part of a broader conversation about men's health and loneliness.
