Toxicology reports released on July 17, 2007, revealed that at their time of death, Nancy had three different drugs in her system: Xanax, hydrocodone, and hydromorphone, all of which were found at the therapeutic rather than toxic levels. Daniel was found to have Xanax in his system, which led the chief medical examiner to believe that he was sedated before he was murdered. Benoit was found to have Xanax, hydrocodone, and an elevated level of testosterone, caused by a synthetic form of the hormone, in his system. The chief medical examiner attributed the testosterone level to Benoit possibly being treated for a deficiency caused by previous steroid abuse or testicular insufficiency. There was no indication that anything in Benoit's body contributed to his violent behaviour that led to the murder-suicide, concluding that there was no "roid-rage" involved. Prior to the murder-suicide, Benoit had illegally been given medications not in compliance with WWE's Talent Wellness Program in February 2006, including nandrolone, an anabolic steroid, and anastrozole, a breast cancer medication which is used by bodybuilders for its powerful antiestrogenic effects. During the investigation into steroid abuse, it was revealed that other wrestlers had also been given steroids.
