The story

Headquartered in Burlingame, California, BALCO was founded in 1983. Officially, BALCO was a service business for blood and urine analysis and food supplements. In 1988, Victor Conte offered free blood and urine tests to a group of athletes known as the BALCO Olympians. He then was allowed to attend the Summer Olympics in Seoul, South Korea. From 1996, Conte worked with well-known American football star Bill Romanowski, who proved to be useful to establish new connections to athletes and coaches such as Korchemny. Conte and Korchemny shortly thereafter founded the ZMA Track Club for marketing purposes, well-known members of it being sprinters Marion Jones and Tim Montgomery. In 2000, Conte managed to contact American baseball star Barry Bonds via Greg Anderson, a coach working in a nearby fitness studio. Bonds then delivered contacts to other baseball professionals.
