Tastes like old school coffee flavored candy, works like a charm
Definite blood-flow increase, I can feel a difference when I'm working out.  Don't take more than 1 every 3 days, on day 2 I get a mild headache that I've noticed, but drinking plenty of water seems to help.  The flavor is the worst part, it's very strong and reminds me of the coffee-flavored candy I used to get as a kid.
