We have been using MTN OPS Ignite for a couple of years now. I first started drinking it when I was working in Colorado a couple of years ago assisting with the damages from the post wildfire flooding. I was working late hours trying to get all the work done and still trying to get up and hit the gym at the hotel every morning before work. The stuff is awesome! I had lots of energy and focus and was able to stay productive for the two months of 16-18 hour days. Once I returned home, my wife started drinking it as well. She is a runner and does some cardio classes in the mornings and I hit the weights most mornings before work. We both really enjoy the benefits of the Ignite product and definitely like that it doesn't have all of the trash products in it that a lot of other pre-workout or energy products seem to have.
