Had another good experience with the stuff today. Went out for my "short" run today and almost didn't take any goo. Felt great when I set out. Thought I would pass out thirty minutes later. Drank 2 tablespoons that I had mixed with 4 oz of water. Felt much better in five to ten minutes. Could be placebo, but, I don't seem to think so. I felt really bad and then felt fine.
