I have been taking protandim for 4 months. The only thing I can tell you is my own experiences, I have never seen it advertised as a miracle pill. I am sleeping all night now because of it. My husband can back me up on that. I am post menopausal and was lucky to get 3-4 hours of uninterrupted sleep a night before I started taking protandim. Now I can sleep up to 7-8 hours and for years I never knew what that was like. You can go to Pubmed and research protandim for yourself. I have heard people mention scam but I have never seen a product with so much science and peer reviewed studies behind it. I don't ever want to be without it again.
