I personally have not used it, but the reports I get are less than positive. It is but an ATP enhancer, these type supplements are nothing new, and have come and gone in the past. The ingredients are nothing special, they will not hurt you. I do believe you can find a better way to spend $45. I have the opinion it is another overhyped suppelement.
