I have used Elite Ops Energy Strips for the past 2 years or so, and totally replaced a habit of pounding coffee from the moment I start my work day until I leave. I start each day with an Elite Ops strip, and feel instantly energized for most of the day, with no crashing. One strip can usually get me through the whole day, but if I need an extra burst or am headed to the gym at night, another strip makes sure I am good to go. I definitely recommend any heavy coffee drinkers make the switch today!
