Guarana - Many herbal supplements contain guarana to suppress your appetite, it contains 2.5 times more caffeine than coffee and is a primary ingredient in energy drinks. Many fitness enthusiasts use it for its metabolism-boosting effects. It boosts energy and performance. You're energy levels are higher and more consistent throughout the day. After three weeks, I started the week off with even more energy and was actually sleeping more soundly than before. I was no longer waking up during the night and tossing and turning because my body was actually able to relax (this is a result of getting rid of the toxins I think). Plus I still managed to lose another 4 kgs, putting me at an unbelievable 12 kgs of weight loss, in just 3 weeks. supplement>> http://phen375supplements.com/
