L-THEANINE POWDER
Works! the taste takes some getting used to.
I bought it to alleviate my ADHD symptoms. Definitely notice an effect in combination with caffeine, but don't use it regularly.

L-THEANINE POWDER
Useful
I use it for two things and for both I do very well: mixed with pre-workout with caffeine. The L-theanine doesn't interfere with the energetic kick of caffeine but it prevents that feeling of overexcitement and acceleration. At night to promote relaxation and sleep. The taste is completely neutral so I recommend this powder format instead of the tablets.

L-THEANINE POWDER
I love it
A friend recommended it to me to relax the nervous system without sleep and indeed I take two teaspoons, one in the morning and one at night and it's great, I also recommended it to my sister and she loves it.

L-THEANINE POWDER
A great product
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.

L-THEANINE POWDER
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.

L-THEANINE POWDER
Wonder
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.

Overnight recovery
I take it at night, it is useful for rest and recovery from intense training and I don't notice that it makes me sleepy.

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

Pending results, I think the pouch format is phenomenal, saving waste, better price and you manage it yourself.
