It is very good if you are not affected by them much. But you probably know that prohormones/steroids, oral especially, tend to lower HDL (good) cholesterol values and shift the HDL/LDL ratio in an unfavorable direction, even if they don't raise total cholesterol much or at all. Since you have had a heart attack, and may have reason to at least be concerned with this effect, I would suggest taking extreme caution. I would discuss this with your doctor first and foremost. Let him/her know you are considering the use of oral androgens, and see what the response is. I doubt it will be advised though, but also don't know this specifics of your illness.
In terms of liver toxicity, you might have reason to be cautious as well. I can't tell you much about the mechanisms involved in the hepatotoxic nature of lipitor, but logic would say that even if 1-AD was adding slight strain to your liver you might not want to mess with it.
In all regards a dermal would probably be better, if you opt to use anything at all.
