Excellent
Great before training combined with caffeine and tyrosine

Surprisingly very useful
I was surprised by its effect. I did not have much faith. Combined with caffeine (there are articles in Elsevier) I have found it very useful. It has improved my reaction times. It has increased the length of time intervals when I can be extremely attentive to something.

Pre-workout basics
Together with caffeine it is a great pre-workout. It helps you to be focused for training. It can also help you to study or work improving your concentration.

Very effective
I have been consuming theanine along with caffeine for years, it helps me to stay focused, and at the same time helps in times of stress, I have not stopped taking it since I tried it many years ago to study. In addition, in capsules it is super easy to take.

Good
At night with melatonin and valerian or even with pre-workout due to its synergy with caffeine.

Good purchase
By itself I have never tried it but only in combination with caffeine .It reduces the jittery effect of caffeine but does not reduce the energy.I recommend.
