GoPack® Reaction and Concentration Capsules are to the needs of gamers. If you want to achieve outstanding performance, you should give your body the right tools to do so. That is why there is a wealth of natural ingredients in each capsule: green tea extract, ginkgo and Brainberry® (aronia berry extract). In addition, we included caffeine (80mg = corresponds to approx. 1 espresso), iron and vitamin B12. All of these are substances that promote concentration and reaction speed when gaming. Brainberry® is a natural aronia berry extract that improves cognitive performance, concentration and psychomotor speed. Iron and vitamin B12 reduce fatigue so you’re wide awake and ready to score.
