You just shouldn't make blind assumptions when you don't know the facts. Every time someone in the bodybuilding community has a heart attack fellow bodybuilders and gear users on the boards sound worse than Joe public that knows nothing about gear. Making blind assumptions about how much gear and this and that is irresponsible. We all do it, we all take that same risk.
For some of us "playing it safe" well that amount could be killing us, and for some that others point the fingers at because they are taking "crazy" amounts of gear, that amount may do them no harm. Genetic predisposition is huge and something none of us can control and realistically something none of us can even begin to measure because we don't have parents and grand parents that used gear.
He had a history of heart disease. That alone without gear is enough to kill someone at that age. 1 in 4 Americans die of heart disease, its the leading cause of death for both men and women. Not all of those are obese couch potatoes. Sometimes it happens to apparently healthy people. So any type of speculation regarding how much gear and blah blah blah in the end makes makes no difference.
