Slow-release caffeine (400mg CaffXtend™)

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.

Compré un bote para probar ya que no confiaba mucho en la liberación prolongada, pero es fantástica si necesitas energía para todo el día y no notar el bajón que te da con la cafeína normal. Si efecto dura 10-12 horas.

Cash

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

desde luego hace efecto pero no recomiendo abusar de ello ya que tiene bastante cafeína, para un uso ocasional esta bien

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.

Muchas veces sienta mal al tomarlo, se ve que es por el tipo de cafeína o igual depende de la persona.

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.

En solo una cápsula tienes 12h de cafeína, que de forma prolongada se va liberando durante ese tiempo. Yo lo noto muchísimo cuando entreno, ya que no noto cansancio, estoy mucho más activo.

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.

Me afecta la cafeína y pensé que al ser de liberación gradual no sentiria un pico ni me daría ansiedad, pero error, la patata a mil y todo el dia a 1000 por hora, mejor si la presentación fueran comprimidos ( para poderlos partir) o otra presentación menos concentrada. Si no te pone nervioso el café, sin duda es genial
