Bought it to fall asleep, I have not had the desired effects but perhaps my expectations were too high.

L-THEANINE POWDER
Does its job
I got the theanine as part of my preworkout booster to stop the jitters of the caffeine powder and in my opinion it helps. I only use it for focus during training, even for mental tasks. The only annoying thing is the closure of the sachet.

L-THEANINE POWDER
Recommended.
I use it together with caffeine to prolong its effect. I recommend it. It has no taste. It helps to lessen the negative effects of caffeine.

In the morning with coffee
I take it in the morning with coffee as a nootropic. I like HSN's single ingredient presentations.

L-THEANINE POWDER
Great for sleeping
I take it just before I go to sleep and it helps. I usually take a long time to fall asleep and this reduces that time. It is also great to combine with caffeine if you take any high doses or need to avoid agitation.

L-THEANINE POWDER
One of the best nootropics
Both very cost-effective and very effective for mood, relaxation, sleep, anti-oxidant effects etc. in combination with caffeine or other stimulants can avoid the sometimes undesirable and stressful over-stimulation side-effects that create unnecessary cortisol.
