Looking at the simply ingredients profile and at the price. For a more efficacious dose on at least one of the ingredients, I'm thinking it's a 2 bottles a month type product, which isn't too bad as it's like sub-$50 for a month supply @ 2 bottles. I'm leaning towards this being more of a stack product though for more potent effect, most likely with some sort of stimmed product (preworkout or stimmed burner). It's on sale and I'm kind of tempted to pick it up... or maybe wait for NP to carry it to see what the crazy NP intro deal will be...
