They were recommended to me and I think they will go better than a coffee, I'll value them properly in my next order.

Product recommended
It is a product that I would highly recommend. I have used it during exam time and it has been phenomenal, it really activates the mind and does not give you the typical sleepiness of studying for many hours.

SMART CAFFEINE *
Perfect
Normally I get sick with coffee, but with this product I tolerate it quite well, not always, but I tolerate it much better in terms of anxiety and high pulse rates. I am a person with very little energy and with this I can last the whole day alert and active.

It does its job
Having a stimulus to train and maintaining it over time, fulfills its function perfectly. In addition, it helps to maintain fat burning for a longer period of time.
