What I find funny is Everyone is so concerned about the effects of testosterone and gh on the heart

I have news for you. Taking ugl gear from these ugl's made in some dirty ass trailor park with contaminated powders and generic gh from china will fuck you up 50 times quicker. And it's not even the fact that these powders are contaminated, too much/too little BA can have quite the negative effect on the human organism.
....Norma, schering, these are multi billion dollar companies made in billion dollar lab settings. Unless you have only used human grade products in your lifetime I would not worry about the effects of anabolics on the heart, really should be the last of your worries.
