Yes, I’ve tried SD-200. Before I didn’t have any energy or want to do anything. And after taking this product I’ve got the energy, and stuff, coming back to me. I heard about it first on the internet, doing some research, and I researched it out, and I chose SD-200, which I finally tried, and I’ve really noticed a difference even though I’ve just tried it for a week. And I’m going to continue using it, as long as everything keeps going the way it is, and I keep progressing back.
