A friend mentioned that large doses of aas could likely damage the heart. I'm not sure what "large doses" are, but he isn't doing large cycles. I thought I read a while back a thread where this was discussed, but I cant find it. If anyone else has info or an opinion, I'd love to hear it.
I'm sure it can put strain on the heart with high dosages of thinks like EQ and anavar that pump the blood faster into the muscle groups. But don't quote me on this, it's all my theory.
Sure AAS can by bad for your heart. AAS not taken probably or abused can increase Blood Pressure and Rise your Lipid Profile, this of course can lead to dmg. Now if your asking does AAS contribute to an enlarging of the heart. I'm sure there are people out there that will say yes, but I do not beleive there have been documented cases. Most people that claim AAS dmg'd there heart already had some kind of Heart Problems before they took them, and probably never knew it, or chose to ignore it. Thats my opinion.
