I'm working on my second container of this. I love this stuff. Great pre-workout
(that's all I'm using it for). I take it 30 min prior to workout and right as I start I get a nice Boost
of energy that I can feel for a good 45 min to an hour. No jumpiness, no jitters, just a good shot of kick-butt. I don't use a lot of energy-boosting stuff normally (no coffee, no soft-drinks/red-bulls) so this might hit me better than someone who's used to tons of stimulants in their system, but I am a fairly big guy and I use this at the recommended dosage and get terrific results. I used up the first bottle and it was 5 days before I could get to the store for another...those were the 4 worst workouts I had had since I started this stuff. I didn't realize how much Boost
it was providing until I didn't have it for those 5 days, then I got more, started it again, and BAM, huge smiles on my face for every workout since. And it tastes good too (both orange and berry flavor, I like the berry the best). I won't stop using this until it stops working.
