Victor Conte Jr. (born July 10, 1950) is an American musician and businessman who was the founder and president of Bay Area Laboratory Co-operative (BALCO), which is now defunct. BALCO was a sports nutrition center in California. In the late seventies Conte played bass with funk / R&B group Tower of Power, appearing on the band's 1978 release We Came to Play!.

Conte served time in prison in 2005 after pleading guilty to conspiracy to distribute steroids and to money laundering. He currently operates Scientific Nutrition for Advanced Conditioning (SNAC Nutrition).

Victor Conte Jr. was born in 1950 in Fresno to Shirley and Victor Conte Sr. He is the oldest of three children in a working-class Italian family. After graduating from McLane High School he attended Fresno City College but dropped out of college in 1969 after being convinced by his cousin, musician Bruce Conte, to join the band Common Ground as its bass player. In 1970 he quit playing in Common Ground and joined the band Pure Food and Drug Act.

At the time Conte's nickname was "Walking Fish", due to his unusual way of moving across the stage when he was performing. He left Pure Food and Drug Act some time prior to 1977. He was a member of Tower of Power from 1977 until 1979 playing bass guitar. He also collaborated during that period with pianist Herbie Hancock and violinist Sugarcane Harris.

In 1984, Conte founded the Bay Area Laboratory Co-operative (BALCO), a sports nutrition center first located in Millbrae, California and later relocated to Burlingame, California. The United States Anti-Doping Agency (USADA) says he developed the banned steroid tetrahydrogestrinone (nicknamed "The Clear") with the help of bodybuilding chemist Patrick Arnold. Pursuant to a plea bargain struck with prosecutors, he entered guilty pleas in July 2005 to one count of conspiracy to distribute steroids and a second count of laundering a portion of a check. He was sentenced in October of the same year to four months in the federal Taft Correctional Institution in Taft, California, with four months on house arrest.

In a December 2004 interview with Martin Bashir on ABC's 20/20 program, he admitted to running doping programs which have broken Olympic records. He said, "The whole history of the games is just full of corruption, cover-up, performance-enhancing drug use." In the interview he implicated five-time Olympic gold medalist Marion Jones and her partner Tim Montgomery, Kelli White (who later admitted using performance-enhancing drugs), sprinter Dwain Chambers, NFL linebacker Bill Romanowski, and others.

On December 21, 2006, Yahoo Sports reported that one of Conte's initial defense lawyers, Troy Ellerman, had been targeted by the FBI as a possible source of leaks to the media during the Barry Bonds probe. On February 14, 2007, Ellerman pleaded guilty to leaking grand jury testimony. It was also reported that FBI agents were an additional source of leaks. In May 2007, Conte claimed to be again providing supplements for Dwain Chambers, who left track and field to play in the NFL Europa league for the Hamburg Sea Devils before returning to athletics in 2008. According to Conte, the nutritional supplements provided via his company Scientific Nutrition for Advanced Conditioning, are perfectly legal.

On December 13, 2007, Conte appeared on CNN before The Mitchell Report was officially released.
