I've taken this product now for (on and off) three years. My husband and I just started taking it religiously for the past 3 months. We both can see a dramatic difference in our energy level and ability to handle stress more effectively. I completely recommend this product to anyone who feels “blah” during the day. A pre-note warning, I’m 5’4 and 113lbs, 1.0cc is too much for me and the Niacin causes my capillaries to dilate and my face to be flushed for a good 25 minutes. Test your cc level on your body weight to make sure it’s enough. Excellent product though.
