It shows

Perfect choice if you need a boost on days when you train in the afternoon, taking it in the morning without affecting sleep.

Perfecta opción si necesitas un empujón los días que entrenes por la tarde, tomándolo por la mañana y sin que afecte al sueño.

Good product

Slower release than the normal ones, I recommend using the normal caffeine ones by splitting them and spacing the intakes to achieve the same effect as with these for a lower price.

Liberación más lenta que las normales, recomiendo usar las de cafeína normales partiéndolas y distanciando las tomas para conseguir el mismo efecto que con éstas por menor precio.

Works great

I use it in ultra trail races and it works wonders because you avoid the peaks and thus the subsequent drop. It gives you a high and stable activity in the race.

La uso en carreras de ultra trail y funciona a las mil maravillas porque evitas los picos y con ello el bajón posterior. Te proporciona una actividad alta y estable en la carrera.

Well

Keeps you focused on tasks without distractions by keeping you wide awake and alert. It is less potent than time-release caffeine anhydrous.

Te mantienen enfocado en las tareas sin distracciones por tener el estado de alerta muy despierto. Es menos potente que la cafeína anhidra de liberación prolongada.

Acceptable

Acceptable results, but there are products with greater adrenergic activation. The effects are very mild and imperceptible in some cases.

Resultados aceptables, pero existen productos de mayor activación adrenérgica. Los efectos son muy suaves e imperceptibles en algún caso.

Activation

Good sensations after a week of use. I use it on specific days of hard work taking it around 7am and during the day I don't feel the occasional fatigue or the desire to take a nap after a midday meal and then I have not had any problems sleeping around 10pm at night.

Buenas sensaciones tras una semana de uso. Lo empleo en días puntuales de mucho trabajo tomándolo sobre las 7am y durante el día no noto los bajones de cansancio que de vez en cuando suelen llegar o esas ganas de siesta post-comida de medio día y luego no he tenido problemas para dormir sobre las 22h de la noche.

I need to try more

I bought it for long car trips and study days. The times I've used them they seem to have done their job.

La he comprado para viajes largos en coche y para jornadas de estudio. Las veces que la he usado parecen que han hecho su función.
