In general, a good and a working product. Especially when there is aerobic exercise, to power - too much, but not so clearly. On the cardio you run noticeably faster and longer, and power rather more endurance (greater number of approaches, less rest time). Taste - Concentrated Fanta, direct strong chemical. But I quickly swallow in one gulp and drink water - so normal. More notice if you drink, do not s before more than an hour, it can hurt the stomach - perhaps due to the acid. Therefore, I eat some fruit, and drink carnitine Chaz begin half an hour workout. I took off a star for that feeling in your stomach, but ordered again.
