But at the same token, bodybuilding isn't exactly a heart-healthy sport either. I don't think a healthy person, from a regular dose of Jack3d, is going to have a heart attack though. I bet that runner, in addition to having heart problems, was abusing the pre-workout. I'm guilty of it too since I don't "feel" it when I take just one scoop.
