H-Blocker, 600 gramsstar rating 5AnonDecember 18, 2009Just started using it. Already loving it. Immediate effects on strength and especially strength endurance. Added several reps to every set in my workout - no sweat.

H-Blocker, 600 gramsstar rating 3frankJanuary 22, 2007I had used this for about 2-3 months now twice over about 8 months. The first time I ever used it, i was really weak and shaky during the first week, but literally exploded with strength and endurance in week 2 with it getting better every week. Second time around I used it though, my body wouldn't get used to it, and I had much worse symptoms... could not catch breath, nausea, faintness. They didn't go away in a week, so i stopped taking this. I believe this to be because it's strongly caffeine based, and I never drink any sort of caffeine.... at all, so if you don't get the side effects, it's an awesome product and works great, but if you do , get off.
