Six Star Pro Nutrition Thermogenic Shred has a powerful caffeine Formula designed for intense energy, focus and advanced weight loss.
It is the most economical way to try Grains of Paradise. A novel ingredient that raises the body's metabolic rate and core temperature. Preliminary studies indicate that it may result in a reduction of body weight.
I've started taking it and while on it I did not notice any more energy than other products of this type but did feel like a person with a fever. Sweating and chills. Interesting.
Other cool ingredients are Theanine which removes some of the jitters of caffeine. Along with Green Coffee, Cocoa and Yohimbe. At $16 for 30 days worth, Shred is the best value for a fat burner. You can find it at Bodybuilding.com or on Amazon.com.
Definitely worth trying.
