In 2003 a number of current and former Oakland players such as Bill Romanowski, Tyrone Wheatley, Barrett Robbins, Chris Cooper and Dana Stubblefield were named as clients of the Bay Area Laboratory Co-Operative (BALCO). BALCO was an American company led by founder and owner Victor Conte. Also in 2003, journalists Lance Williams and Mark Fainaru-Wada investigated the company's role in a drug sports scandal later referred to as the "BALCO Affair". BALCO marketed tetrahydrogestrinone ("the Clear"), a then-undetected, performance-enhancing steroid developed by chemist Patrick Arnold. Conte, BALCO vice president James Valente, weight trainer Greg Anderson and coach Remi Korchemny had supplied a number of high-profile sports stars from the United States and Europe with the Clear and human growth hormone for several years.
