Brian McNamee told federal prosecutors and congressional lawyers during his deposition on Thursday that Roger Clemens' wife Debbie took human growth hormone (HGH), according to a source with knowledge of McNamee's testimony. Lawyers for both Clemens and McNamee could not be immediately reached for comment. It's not immediately clear what year she took HGH or for how long. The source said McNamee trained Clemens' wife how to inject herself. HGH is an anti-aging drug used by athletes primarily to aid their healing process from an injury.
