Super
Great product. Has a good effect. Whether in everyday life or during sport. I am fit and focused, but not as exhilarated as with caffeine tablets. I take it regularly.

Gentle and prolonged effect.
Smooth and prolonged effect, without noticing the quick caffeine highs. Ideal for a day trip, mountain outing or endurance sport.

Interesting as an alternative to coffee.
It does not produce any type of anxiety or irritability that a cup of strong coffee usually generates in me, nor does it disturb my sleep if I take a capsule first thing in the morning. As for the positive effects, it is difficult to estimate, although the sensation is positive.

Good stimulant and relatively long-lasting effects if you want to have energy and stay motivated during the day.

Recommended.
I use this caffeine during times when I am more tired and need a boost of energy. The truth is that sometimes I don't feel like drinking coffee or an energy drink. These capsules are convenient to swallow and, at least for me, they work quite well.

Almost perfect
Slow-release caffeine is very interesting for people who want to reduce their coffee intake. It helped me wean myself off energy drinks.

Good caffeine.
This caffeine is somewhat peculiar, because it does not give you that initial push, let's say it is more progressive, which makes it a very good option for those who get very nervous with normal caffeine. Recommended.

Good product
I like this caffeine that doesn't give the knockout effect but acts in a much softer way anyway giving you the right boost for a long term effect. highly recommended for endurance sports

Excellent.
Perfect to give the maximum during training. I don't use them regularly, only when I'm a bit more apathetic and the effect is immediately noticeable.
Minimum purchase of units!
