Perfect for energy
Perfect for long lasting energy. I do not recommend taking them in the afternoon or if you can take a lower dose such as 120-200mg of caffeine.

It works
I bought them when I read in the reviews from colleagues who highlighted the suppression of the typical downturn after a few hours. It seems to be true

It is well
It does not produce the high that caffeine in pill form usually gives you, but neither does it produce the crash after a while (this is the best thing). It produces a stable dose during some hours, it even allows you to concentrate to study or work. Highly recommended.

Effective after half an hour
After half an hour you notice the effect of the caffeine and it is true that it lasts longer than normal caffeine. It's great for studying

Full throttle
The first shot I took was at 7 in the morning, I had energy throughout the day, yes my mood changed a little (I was like pissed off), the problem came at bedtime, I can assure you that I turned more times in bed than a one-armed man in a boat.
