SLOW-RELEASE CAFFEINE (400mg CaffXtend®)
Peak power
I take it before a match and I notice the energy peak after 20 minutes. I recommend it: increased performance and concentration

Effective.
You don't notice any highs or lows, so you are active all day without feeling rushed. I love them because other stimulants had no effect on me. The capsules are tiny.

Excellent product
Excellent product! I bought it for my son who has started his first job. He notices much more energy throughout the day, it even reaches him in the afternoon when he trains hard at volleyball. I will definitely buy it again.

Regular
The truth was not good, I did not notice anything. I increased the dose but I felt too uneasy but with no visible effect.

Interesting product.
This caffeine gives you extra energy during the day, but it doesn't give you a spike or high; it is less stimulating than a regular caffeine pill but with a much longer half-life, and it doesn't make you jittery or anxious. Very happy.

Without giving any kind of caffeine high, it keeps you constantly alert, and I find it very effective in the evenings without having to drink so much coffee.

Superbien, it wakes you up and then you do not notice the downturn, highly recommended, large capsules.
