works as advertised!
I was skeptical at first as to whether or not this would work.  I used it and was pretty impressed with the results, as I was able to power through entire Hammer and Chisel workouts without having to pause in the middle of sets. I noticed a marked difference on days I didn't use the product, as I was significantly more sluggish.  In addition, the taste is great. Not chalky at all.
