SMART CAFFEINE
Great
I loved it! I took it before playing a Padel match at 9 pm, when I was already tired from the day, having trained, +15000 steps, etc. and it activated me perfectly. I will try to take it only at specific times, as I consume a lot of coffee and I do not want to become too tolerant, yes, the next day I had a headache but I can not say it was because of caffeine, it could be fatigue or any other independent factor, I will continue to buy it.

I bought a small bottle to try and I will repeat. I notice its effect by taking one capsule at breakfast.
