    The testimony remained intimately personal for Barry Bonds as his trial resumed Tuesday.

    Prosecutors called two witnesses to the stand to discuss the urine samples Bonds provided during the 2003 season. Prosecutors allege those samples tested positive for the designer steroid THG.

    The two witnesses, Barry Sample, chief science officer of Quest Diagnostics, the company that analyzed Bonds' urine, and Dale Kennedy, who collected the sample, were necessary to establish that Bonds' samples were handled properly and can be used as evidence.

    The former head trainer for the Giants also testified. Stan Conte told the jury that Bonds became significantly more musclar during the 1999 baseball season. Conte said Bonds gained between 10 and 15 pound and developed acne on his back that same year.

    Tuesday morning was far less dramatic than the testimony of Bonds' former mistress Monday. Kimberly Bell testified that Bonds told her he used steroids and became verbally abusive toward her at the end of their nine-year relationship.

    Former AL MVP Jason Giambi and his brother, Jeremy Giambi, were both at the courthouseTuesday. The brothers have both admitted to using performance-enhancing drugs they obtained from Bonds' personal trainer, Greg Anderson. Jason Giambi did take the stand Tuesday afternoon.

    Other athletes who are on the government's witness list include several former teammates of Bonds: Armando Rios, Benito Santiago, Bobby Estalella and Marvin Benard.

    All the players except Jason Giambi, who is with the Colorado Rockies, have retired. He formerly starred for the Oakland Athletics and has all but admitted he used steroids during his prime years.

    Bonds, MLB's record-holder for home runs in a career (762) and a season (73), is accused of lying to a federal grand jury for testifying in 2003 that he never knowingly used performance-enhancing drugs.

    Prosecutors hope to use the players' testimony to bolster their position that Bonds knowingly used steroids obtained from Anderson.
