Allow me to re-type my post in a way that may be easier for you to understand...
"If I had suffered a HEART ATTACK and was AT ALL concerned about SURVIVING, I would listen to my HIGHLY TRAINED CARDIOLOGIST over ANONYMOUS FORUMS POSTERS"
Sure, when it comes to the minutiae of the latest supplements, some posters here may be better informed. But when it comes to making the most out of a damaged heart, you better believe he would do well to follow all doctor's orders.
So what if he isn't able to use SWF? Is that going to make a significant difference for him? Is he really at the level where use of that supplement is going to make or break his progress?
Better to err on the side of caution, than take a risk. Why not have this guy bring the supplement to his MD and have him look over the ingredients. Who knows? Maybe he'll give him the OK. But why take the chance?
There, you see?
