So I picked up some Xtreme Shock today.
Stuff is pretty good tasting, reminds me of a fruity drink (I got fruit Punch).
No bitter taste or anything in it, has 40mg of Niacin and 200Mg of C affine. 20 Calories, no Sugar.
I got this rush/sensation from drinking it, my whole body got tingly/warm (from the Niacin).
It definitely gave me energy to do whatever I wanted. Lasted about 30-40 mins or so. Not bad for a 12oz drink.
Definitely would be a great product to use on a work-out day.
