"There is little evidence that steroid use increases risk of heart disease- though there is some- one needs to take into account the diet of many who use anabolics- which is rarely that clean- so more food + not "clean"- less healthy + cardio is somewhat rare in some circles."
Correct. Also, the high consumption of protein in bodybuilders increases the levels of homocysteine, which is now being shown to be damaging to the cardiovascular system. Lets not forget about the high use of beta-adrenergics, insulin, GH, and thyroidal meds, which all may act to increase cardiovascular damage.
"plenty of men die before 50- the fact that they are brothers makes it MORE likely that it was genetic."
Genetics and, in Mike's case, the bias against chronic exercise, smoking, and past drug use. HIT every other week, or whatever the hell he was advocating in the end, will simply not improve cardiovascular health like routine resistance training.
"Jakobs-klienfelters syndrome( or is that kreuzfeld jakobs)- which some claim is what lyle alzado died of is linked to the use of GRORM as human GH extract taken from cadavers."
AIDS also shows correlations with certain brain cancers and since Alzado was known to have had many sexual partners over his lifetime, increases this probability.
