The negatives of this product are a person can have little idea what may be so in supplement. The ingredients are quite just unknown. And it is a mystery with myself why they'd not disclose such needed information. Ok, I does away with with my tangent. There's no refund for this particular that costs $126.00! At this point correct, I said $126.00 and you don't even have the opportunity to know is actually in pill! There is no refund the street very expensive product falls short of your expectation.
