Subidón
I don't take it on a regular basis but if I need an extra boost before training or need to stay clear because I'm driving at night, I take one before and go for it. XD

SMART CAFFEINE
Keep you awake and take the edge off hunger
1) It helps keep you awake. In my case, I am already very awake in the mornings when I work, but with this I no longer get that heavy sleep in the late afternoon. 2) Interestingly, it also takes away the craving for food. Recently, I have re-discovered another HSN product that fulfills these 2 functions as well: the ASHWAGANDHA and, for the moment, I prefer the latter. Each one can try what works for him/her.

VERIFIED OPINION
SMART CAFFEINE
It is not effective.
I had high expectations for this product, as the concept is very good. However, I have tried it for several days now and have not noticed any effect. I am not eating it.

I do not recommend
I always take caffeine before training and when I tried these, I didn't notice any difference, they hardly have any effect.

VERIFIED OPINION
SMART CAFFEINE
Activation without anxiety
It gives me a plus of energy that comes in handy if I have not been able to sleep my 8 hours of sleep, and it does not give me a rebound effect of anxiety or palpitations. I use it sporadically and it works well for me.
