The Legend: That Eddie Guerrero's death was the direct result of years of anabolic steroid abuse. Why People Believe It: Eddie Guerrero was massive, there's no getting around that fact. For a guy who was a legitimate 5ft6in tall he was incredibly large in terms of muscularity. His arms, shoulders and back were huge. There's little doubt that Eddie used steroids to attain that size. The copious amounts of acne on his back (a common side effect of steroid use) attest to that. In articles about Guerrero's death there is, invariably, discussion of Eddie's steroid usage. Eddie died of acute heart failure due to underlying atherosclerotic cardiovascular disease (essentially a heart attack). Heart attacks are common for people who use/abuse steroids. Steroids may enlarge the muscles but the heart is also a muscle and thus gets enlarged, too. Add Human Growth Hormone to the mix and that's a bad recipe. In March 2007 Eddie was named by Sports Illustrated as having allegedly bought HGH and the steroid stanozolol in early 2005 from an online pharmacy. Guerrero, along with then-current and other former WWE performers, was also named in the Signature Pharmacy scandal in August 2007. Eddie was named as having bought he steroids testosterone and nandrolone, along with the estrogen-blocker anastozole (to prevent forming breast tissue) on November 2nd, 2005 just 11 days before his death. Is It True: Given Eddie's past problems with prescription drugs and alcohol, it's hard to say that steroid abuse was the sole cause but Guerrero clearly took the muscle-building drugs and they undoubtedly contributed to his heart attack.
