EQ and Masteron bad for the heart?

[alan1973]

I did some research and marked out the gear that is rough on the heart, but EQ and Mast was not marked off. Then I went to some boards and some folks either think, or feel they are. I have to avoid certain gear because of heart related problems, like Tren, anadrol and Deca. I also have to keep dosages lower than most say they use. (50-75% less since all gear affects the heart in some way from what I have read).
Would like some real life experiences here from you all.
Thanks in advance.
