Will be interested to hear your review. I'd be very surprised, and skeptical to be honest, to hear that this stuff is of any value at all. There is little to no science at all, and no solide studies, that show any of this stufff actually leads to weight loss directly on its own. The GBB that is/was a buzz boosts Carnitine but even that has been shown to be of most effect in people that are deficient.
Honestly that looks like a fair bit of money down the toilet!
