Help/info Re:heartfailure

Dear Dr Shultz,
My father-in-law is struggling with stage 4 heart failure(congestive). I started him yesterday(May 1) on your heart forumula. He is willing to try it, he is very weak from this ordeal. My question is how long would be a fair amount to expect to see results. He is very discouraged and I wanted to be realistic on how soon we may see it working for him. Thank you, I use many of your products and study natural health because of you....Nancy Tweet
