SLOW-RELEASE CAFFEINE (400mg CaffXtend®)
Care
many times it feels bad when taking it, it may be because of the type of caffeine or it may depend on the person.

SLOW-RELEASE CAFFEINE (400mg CaffXtend®)
Great product
In just one capsule you have 12 hours of caffeine, which is released over a prolonged period of time. I notice it a lot when I train, because I don't feel tired, I am much more active.

SLOW-RELEASE CAFFEINE (400mg CaffXtend®)
Too much
I am affected by caffeine and I thought that as it is gradual release I would not feel a peak or give me anxiety, but mistake, the potato to a thousand and all day at 1000 per hour, better if the presentation were tablets (to be able to split them) or other less concentrated presentation. If you are not nervous about coffee, it is certainly great.

Not very effective
Small size capsules. To be honest I haven't noticed much of that prolonged release on long study days.

It does its job
Neither coffee nor cola made me stay awake and focused, the caffeine release makes me perform better for about 12 h every day.
