Wow !! That's really amazing.It's been a while since I posted but thanks for the feedback.My husband did not take the serrapeptase for long...had no patience with natural stuff but so far he's been doing okay.I'm sure the arteries are still partially blocked though since he didn't take anything else for it.I'm going to try and convince him to go back on it.What brand did your friend take?I had bought Doctors Best but I would like to find out if there is a better one out there.

Really appreciate your post and glad to hear that your friend has been helped.
