After 10 minutes I got the familiar tingling in the hands and to go to train an urge. You then not trained is one (without the tremor what you get from coffee) just madly awake. From the dosage is 1-3 Scoops on the package. I take one and the effect lasts for barely 2 hours. The taste refreshing green apple. The only downside: the next day you have here and there the odd pimple. Because so wants without being too vain to push his performance, which I can recommend the stuff.
