Great to hear from you, Tom. You didn't do badly on the Bruce protocol at 5+ minutes; but, did you really HAVE to stop due to leg pain? How does that correlate with your own stress testing (regular exercise)?
You have had a lot of plaque to overcome. I say stay the course, continue as you stated, also with Vit. C (2,000 +) and L-Lysine (2,000 +) and maybe some L-Arginine (500 - 1,000) and stay the course. If you don't HAVE to have surgery, avoid it at all costs.
Stem Cells. They will help grow new blood vessels, maybe. But they don't replace the ones you have, or clean them. And ultimately, unless it is very well hidden research, I don't think we know the REAL outcome of stem cell therapy for circulation.
By the way, is it still possible to get help with a web site?
Very best to you/ya'll.
