I've been using this product for over two years, and it's made a huge difference in my training. It also saved me during the World Championship in Kona! I was DYING on the run, and I ran by BASE Performance tent at the top of Palani. I begged for some Aminos and they prepared a bottle and one of their guys ran it up to me. I was never so grateful. It brought me back to life. Highly recommended.
