I was suffering from fatigue, poor sleep, and overall poor physical performance. My trainer recommended I try this product at a rate of 2 capsules, 3 times per day for two weeks. So far it has made a tremendous difference in my energy levels and physical performance. I don't hit the "wall" at 3 or 4 in the afternoon anymore and I'm feeling more rested after sleeping. I just hope I don't revert back once I go off this stuff. Unfortunately, it is awfully expensive and I can't afford to take it on a regular basis at the same dosage.
