I'm normally that guinea pig that loves to try all the new products. With me though, I like to try stuff that is different than everything else out there. I was a huge fan of 5 hour energy shot when it came out. It led me to try other ones, but just didnt give me the kick I was looking for.
When I saw fixx extreme, advertised at 400mg of caffeine in a teaspoon, I was like "woah". So I tried, Oh MY GOD! Seriously, this stuff amazingly works. My only negative is this is NOT for everyone. I you can't handle serious amounts of caffeine, you dont want this. But ultimately, I'm hooked and ponied up for a full box.
It seems like every time I turn around, there is another new energy product staring me in the face. This one is a cappuccino-flavored energy shot (5mL) with an astounding 400mg of caffeine, plus taurine, arginine and vitamin B12. To put this in perspective, a 16oz can of Monster contains only 160mg of caffeine...and I didn't think I'd put "only" and "Monster" in the same sentence.
This promises all-day energy, but that's not really what you get...you get an uncomfortable rush that lasts for a long time, but after a while you kind of wish it would chill out. This product would be better if it was less concentrated, and then you could mix it with water and space it out into reasonable doses. Taste was pretty good.
