I also have a tub of Enhanced which I got months ago now and have only used it twice.
Unfortunately after all the hype, it was nothing special. It takes 30 mins. to work and then makes my face all red /flush probably from the yohimbe. I still rate Craze as the best pre-workout on the market, although I did try a Hemavol Watermelon sample today and got great pump, energy and the taste was even better than Furious Melons...so will be ordering some soon.
