I just recently picked up some caffeine/boost supplements from GNC. It's called Thermo-Boost. Has anyone used this stuff before? Looks like there's a whole lotta caffeine in these bad-boys...but the saleperson talked me into picking this up in order to gain more energy and lose weight quickly.
Any feedback would be appreciated.

Once ephedrine was banned, companies began throwing in several "exotic" ingredients to make the supplement seem more effective: green tea, guarana, yerbe mate, cocoa, gotu kola. All of these ingredients have one thing in common--they contain caffeine. Yes, many they contain antioxidants, particularly polyphenols. However, the only one that would pose any use as a weight loss adjunct is ECGC, which is found in green tea. Unfortunately, a large amount of this compound (more than is in any everything-but-the-kitchen-sink products) would be needed to facilitate heightened fat loss.
ThermoBurst (which I believe is the product to which you refer) is much the same. It has a considerable amount of caffeiene along with tiny traces of other exotic caffeine sources. There are also some other ingredients that could be considered mildly thermogenic, but they are in tiny, tiny, traces that are not biologically plausible.
*EDITed to add the following paragraphs:
Yes, ThermoBurst does have a lot of caffeine, which
can be useful in facilitating lipolysis (although not so much by itself). However, you would get a lot more mg per dollar by using Vivarin as your caffeine source. In other words, don't buy it.
