By EPIC Performance. This is great for anyone that trains "HARD".
Contains Peak-ATP. This stuff will get you through the TUFF workouts. I notice it most on Bike rides. 1hr after I take it my legs just never seem to fatigue. I can hit a threshhold and recover quickly...and hit it again. I never seem to tap out on the energy side. When you ride 30+ miles on less that 250g of carbs that day....I know it works.
Basically it is what the product of Creatine produces in the body ATP...which in pure cellular energy. I will be taking a few doses on the 100 mile ride Sunday.
