I know of one example of a 28 year old otherwise healthy male who had an MI after 1 year of self-administering 200mg T/E week.
The Iranian Trenbolone study is interesting, because he was running it for a year straight I believe, sometimes it's not really a matter of severe / permanent damage to the blood vessels, plaque, or remodeling, sometimes it just comes down to a combination of things and bad luck setting off an MI. Taking trenbolone for 365 days may not be enough to cause significant remodeling, but 365 days where something can fuck up just because of a combination of factors is enough.
When people analyzed Dallas's autopsy report and they noted all these irregularities in his heart, thyroid, etc, you have to wonder how many other 300lb'ers would have those same issues mid-blast. Maybe most? But not all of them are dropping dead. Your body isn't a finely engineered Swiss watch, it's an imperfect biological entity and you can't assume just because you have good health markers nothing will happen. Or even bad...anyone here have grandparents who smoked from childhood and lived till their late 80's?
