Patrick Arnold: The "Brains behind BALCO" and steroid chemist mastermind reveals the inside story of sport's biggest scandal

It’s now more than 20 years since the BALCO scandal shook the world of professional sport to its foundations, but the aftershocks are still being felt with public trust in elite performance yet to recover.It was and will forever be the most shocking and sensational sports exposé: a conspiracy to create and deliver undetectable performance-enhancing drugs to some of the most high-profile athletes in the world to give them an insurmountable advantage to dominate their rivals.Household names, including Olympic gold medalist sprinter Marion Jones - who was forced to return her five Olympic medals - and men’s 100m sprinter Tim Montgomery - whose world record time was struck from the history books - became synonymous with the scandal. Others, such as multiple Major League Baseball MVP and record home run hitter Barry Bonds, were implicated without ever failing a drugs test.In all, dozens of athletes had their previously inspirational and illustrious careers forever tarnished by their associations with BALCO.While one man, BALCO founder Victor Conte, has sought fame, money and attention before, during and after his exploits were exposed by a US Internal Revenue Service investigation - most recently appearing in the Netflix documentary “Untold: Hall of Shame” - another figure, one arguably more influential to the entire BALCO operation than Conte or anyone else, has remained almost entirely in the shadows.Until now.In an exclusive and long-awaited interview, we tracked down Patrick Arnold, the enigmatic and reclusive chemist who created the designer anabolic steroid central to BALCO’s success, and convinced him to break his silence and reveal his side of the biggest doping story in the history of professional sport.BALCO not only catapulted the clandestine world of sports doping into a largely shocked and unsuspecting public, but also revealed the huge risks athletes were prepared to take to get to the pinnacle of their sport.In an exclusive Unfiltered conversation with contributing editor Dr Jonny Rees, Patrick Arnold unveils the intricate tapestry of deception, ambition, and scientific ingenuity behind the BALCO scandal, and his revelations lay bare how the allure of unparalleled performance and promise of immortality seduced some of the biggest names in professional sport.More than two decades on, the catastrophic legacy of BALCO is not simply one of tarnished records and fallen idols, but a profound erosion of trust, respect and honour in competitive and professional sports.And so Arnold’s side of the story is more than a sensational spectacle of how a few stars burned brightly before quickly being extinguished: it serves as a cautionary tale about the cost of victory at any price and the sheer fragility of sporting integrity in the face of irrepressible ambition.For exclusive access to all Unfiltered's video interviews, features and documentaries visit https://unfilteredonline.com/Get in touch in the comments below or talk to us on:Email: [email protected]: https://www.youtube.com/channel/UCGSV7XVaBYUYq5YidLI12owInstagram: https://www.instagram.com/unfiltered.extraTwitter: https://twitter.com/UnfilteredExtra
