Not a good product it gives u jitters, not much energy and also u will NOT be able to sleep at night for sure
Capsules are horse tablets, hard to use if you find difficulty with tablets. Taste was very sour if the capsule breaks in your mouth, most likely the pepper extract.
I did find an increased energy boost when using it, however I was getting sores on the sides of my mouth. When I stopped they went away.
Great product! What the label says it delivers to the fullest no gimmicks nob.s. just results!
