It lasts all day.
I bought a bottle to try as I didn't trust the extended release much, but it's great if you need energy for the whole day and don't notice the comedown you get with regular caffeine. If effect lasts 10-12 hours.

of course it has an effect but I do not recommend abusing it as it has enough caffeine, for occasional use it is fine.

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.

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.

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.
