San Francisco Giant player Barry Bonds has been accused of lying to a grand jury. In 2003 the baseball player made statements that he was deceived into taking steroids by his trainer. However, prosecutors are reporting that Bonds was aware that the supposed flaxseed oil was performance enhancing drugs.

Bonds is also accused of lying when asked about injections that his trainer was giving him. The federal prosecutor for the case is asking the jury to find the home-run superstar guilty of lying.

Bonds’ prior girlfriend was brought in to testify about changes she had observed in the baseball player during that time. She stated that he suffered from mood swings, hair loss and acne. Prosecutors confirmed that these side effects could all be attributed to steroid use.
