I chose for exams caffeine in the form of tablets to take, when I'm tired I can not usually focus so well. Well I bought these capsules and relies on the positive reviews. I once got arrested and found that the have no noticeable effect, the capsules during the holidays to sample. Then I had also taken two times capsules suddenly and unfortunately does not feel any effect !! I am also not a person who otherwise caffeine in the form of coffee or energy drinks to be so I can rule takes a caffeine desensitization. For me, a total flop and therefore no recommendation to buy from me !! Will continue to have to see me,
