Gives some good energy during workout! Only some trembling in the first 20minuits after taking it!

Fed up with drinking many many cups of coffee before workouts, I tried to take caffeine directly as tablets. Primaforce beautifully delivers what's expected.

Great decision for those who cannot drink coffee for any reason (or don't like it). I don't feel great additional power, but I'm not tired much more time. I bought this product twice and should buy it again.

Nice well-known stimulant. One dose (200mg) was more than enough (combined with 20mg of DMAA) to give me an extra focus for my workout at the gym.
