Energy and Sweat!!!
I really like this product. I first tried it when it was sent to me in my Pro box. I’ve been using it ever since, approximately a year. It helps to burn off the calories at work and at my workout and also gives me extra energy.

I took Greende for first time and my heartbeat increased to 152 for 6 hours! I was dizzy and jittery and unable to do anything that would increase my heart rate. I feared my heart would explode like the packaging suggest, like a grenade.

I went to buy my second bottle and called every local GNC and was told they no longer have them in stores, why are they not carrying them?
