Good complement
I have tried several similar products and this is the one that suits me best. It has its necessary activation point but without overdoing it.
He probado varios productos similares y este es la que más se adapta a mi. Tiene su punto de activación necesario pero sin excederse.

It works
It is the first time I take it and it works. I don't feel the typical sleepiness after a morning of mental exertion.
Es la primera vez que la tomo y funciona. No noto el sueño típico tras una mañana de esfuerzo mental.

Great
I take them in the morning on an empty stomach when I wake up. If you practice intermittent fasting this supplement is a plus to improve results.
Las tomo por la mañana en ayunas cuando me levanto. Si prácticas el ayuno intermitente este suplemento es un plus para mejorar los resultados.

If you need an extra boost of energy, this is the product for you.
I'm studying, working and doing 1.5 hours of exercise a day at the gym. There are times when I don't sleep well and the day ahead is so intense that I was looking for something that would give me extra energy, but without the side effects of drinking a couple of coffees: palpitations, nervousness? I came across this option and the truth is that I couldn't be happier to have bought it. I take a capsule on days when I need extra energy and it works perfectly. I notice that the tiredness goes away, that I am more active, more awake and ready for whatever the day has in store for me. All this, without side effects or anything like that; what is true is that if I need that "shot" of energy in the afternoon, I usually take the capsule before 18h. It has no taste and the convenience is that you can take it wherever you want and take it when you need it. Of course, I usually do not take it every day because we know that the body gets used to it quickly and then asks for more, but taking it every other day works great for me. An excellent option.
Estoy estudiando, trabajando y hago 1,5 horas de ejercicio al día en el gym. Hay veces que no duermo bien y el día que se presenta es tan intenso que buscaba algo que me diera un extra de energía, pero sin los efectos secundarios de tomarme un par de cafés: palpitaciones, nerviosismo... Buscando me encontré con esta opción y lo cierto es que no puedo estar más contenta de haberla comprado.
Yo me tomo una cápsula los días que necesito un extra de energía y lo cierto es que funciona a la perfección. Me noto que el cansancio se va, que estoy más activa, más despierta y preparada para lo que me depara el día. Todo ello, sin efectos secundarios ni nada por estilo; lo que sí es verdad es que si ese "chute" de energía lo necesito por la tarde, la capsula me la suelo tomar antes de las 18h. No tiene ningún tipo de sabor y lo cómodo es que te la puedes llevar a donde quieras y tomarla cuando necesites.
Eso sí, yo por lo general no la tomo todos los días porque ya sabemos que el cuerpo se acostumbra rápido y después te pide más, pero tomándolo días alternos me funciona genial.
Un excelente opción.

Essential
For me an essential supplement in my daily life. Not only for the extra energy but also for the activation effect. I recommend that if you stop noticing the effects do not increase the dose. Take a two-week break from caffeine and that's it.
Para mi un suplemento imprescindible en mi dia a dia. No solo por ese extra de energia si no por el efecto de activacion. Recomiendo que si dejas de notar los efectos no subas la dosis. Haz un paron de dos semanas de cafeina y listo.

Brutal
Its effects are brutal, concentration and focus to the maximum at an unbeatable price, you notice the prolonged release of caffeine as it does not cause the downside that makes you normal caffeine after a few hours.
Sus efectos son brutales, concentración y focus al máximo a un precio inigualable, se nota la liberación prolongada de la cafeína ya que no provoca el bajon que te hace la cafeina normal al cabo de unas horas
