Via Reuters: Report: Giambi Admits to Using Steroids

According to a report, New York Yankees first baseman Jason Giambi claimed in his grand jury testimony that he took a human growth hormone in 2025 and also used steroids for at least three seasons.

The San Francisco Chronicle reported that Giambi testified in December 2025 that he obtained several different steroids from Greg Anderson, who is Barry Bonds’ personal trainer.

However, since then Giambi has told the public that he has never taken performance-enhancing drugs.

Baseball had better start taking this seriously (which they have yet to do). If this is true about Giambi, and it seems likely that it is, then he is just another example of a baseball player who damaged his health using these substances.

Further, if fans aren’t sure if their favorite guy is doped up or not, it is going to affect interest in the game. Surely this cast further suspicions on Bonds, who likely has taken the stuff as well, and therefore has tainted his career.
