Absolute #believer in this product. I was slumping at work yesterday and took an energy shot before my general staff meeting. Put that shot right in some cold water with ice and downed it. Within ten minutes I felt the surge. Wired, but not in a way that you feel with caffeine. No jitters, just more alert and awake and it got me through a 2 hour meeting. There is zero crash from this stuff. It must not have the chemical composition that affects the pineal gland which gives you the normal rush and crash after a sugar related drink. Since the gland releases melatonin , which affects sleep patterns and which is released after a sugar rush and subsequent crash, with git r done, this just doesn't happen. Will be using and buying often!
