Review: GOOD RESULT - THE BEST
Review: It works - I used this product for about 45 days before my last century. On the plus side, it definitely works. I feel like it allowed me to train harder and faster than my body was naturally capable of. That might sound like a positive, but I believe it caused me to over train, and I was pretty flat for the century. When I do my next century I will most likely start using it a just a week or two before the ride.
