The Alfredo espresso has 160mg of caffeine and gives you a boost! These capsules are supposed to have 200mg AND THEY DO ABSOLUTELY NOTHING! I tried 2 capsules together AND NOTHING! They are probably fooling us with the mg. And I don't even drink coffee every day to say that it doesn't affect me.

I have been using it for 3 months now and it does work, but it is low intensity for a long duration. Personally, it takes me about an hour to feel it, and it lasts around 4 hours. It's not an intense boost but a lack of fatigue, just right for daily use upon waking up. However, for a more intense boost, I drink Monster, and I will also try Mutant Core tablets, which are even better value at 0.0003 euros per mg, while Olimp is 0.0005 and Monster is 0.01.

It does quite well what it promises without any side effects, such as intestinal disorders that I had with another product. It provides more physical energy and alertness if you are awake, but less clarity.
