Hi there! I have tasted one dietary supplement complex on the basis of organic chocolate with organic caffeine. It is elaborated specially for energy boosting. There is a link: (SPAM LINK REMOVED) I was surprised how effectively it works. It gave me enough energy for the half of the day and for the training as well. (I took it 3 hours prior to training). Moreover, after the training was finished, I still felt alert. But before, I felt crushed afer my trainings. And they are delicious) I was fed up with all these chemical capsules, powders and pills. That`s why I wanted to taste something organic and delicious. I strongly recommend you to taste))
