The Bay Area Laboratory Co-operative (BALCO) was a service business for blood and urine analysis and food supplements. The BALCO affair was a drug sports scandal uncovered in 2003 by journalists Lance Williams and Mark Fainaru-Wada. BALCO owner Victor Conte, vice president James Valente, weight trainer Greg Anderson and coach Remi Korchemny provided several high-profile athletes from the United States and Europe with the designer steroid Tetrahydrogestrinone and growth hormones for several years.
