Tracey is right about Dr. Clark. She has helped so many people. I have a zapper and use it and believe in it.
Look at it this way---Dr. Clark and Dr. Schulze
give way more than they receive---Dr. Clark explains how to build your own zapper. She gives out all of her formulas. Dr. Schulze
does the same thing. All of his herbal formulas you can make yourself if you choose. He also gives away something with everthing you order from him.
Both are my heroes!
