As a person quite sensitive to caffeine I have quite a few problems when consuming (anxiety), with theanine I have completely reduced this sensation that caffeine produces in me.

I consume this product daily, and I love both its texture and its properties. Likewise, its presentation is also highly recommended, in a perfect container for its conservation.

Good product.

It is very good for me to counteract the effects of caffeine but it completely cancels them out for my wife. Fast shipping and well packaged.

Wonder
Carlos 27/05/2025
What an incredible product, despite the price it comes in enough quantity for many shots, it is important to keep it well, I spent some extra money to buy an airtight glass jar with easy access to it. I do not recommend taking it at bedtime as it causes some people to have vivid dreams and wake up as in my case.

Too much quantity for what is consumed, with the small format you can easily have enough product for two years.
