Paradoxically Stimulated and Sedated [Trip Report]
L-Theanine
Date: April 21st, 2012

Dose:
T+0:00: 400 mg, oral, L-Theanine

Today I decided to give L-theanine a run after reading that it had some stress-relieving effects and reading about its pharmacology. It increases levels of GABA and dopamine and has some affinity as a NMDA receptor antagonist, meaning overall it's a sedative, stimulant, and dissociative. The bottle I bought had one 200 mg pill as the recommended daily dose, so I chose to double it for this test; the LD50 is said to be very high. As a final note, I'm feeling rather sick today so my resulting lethargy may have skewed the results slightly as far as how much energy the dose gave me goes.

I took the dose in the early afternoon and waited for it to set in, totally unaware of how long it was supposed to take or what the duration of the effects would be. Within half an hour I was feeling noticeably sedated, but not necessarily enough for me to say it definitely wasn't placebo. But by the hour mark I could feel a bit of a head fogginess that I recognize from other GABA drugs, and the music I was listening to had started sounding wider and deeper. Though this could have been from NMDA antagonism, I'm going to say it was likely at least mostly from the increase of dopamine. The mood it created was one of being paradoxically stimulated and sedated. Figuring that staying on the couch would be a waste of a dose, I decided to go for a walk in the nearby park forest.

Unexpectedly, once I actually got outside I had a good deal of energy. Or rather, my body was moving very swiftly and fluidly, despite feeling rather at peace. It was a great day outside and being in the sun and feeling the wind rush by me was very soothing. Once I reached a hill that I really like in the area I could tell that my senses were somewhat expanded. I felt like I had a wider panoramic view than normal, as if my vision had been flattened somewhat horizontally, but I believe that was only an illusion caused by the fact that I was taking in a very large quantity of visual data at once (like the opposite of tunnel vision). Among the forest wall I could easily spot several complex patterns of leaves and branches, and colors were fairly saturated in a way that was almost cartoony, but not quite. There was definitely a dopaminergic filter applied to the world, but given that I am very accustomed to this mental change and can pick up on it easily.

I ended up walking down a path in the forest and found myself feeling very connected to nature. I watched bugs fly around me and animals scamper through the trees as I just walked by. The feeling of mental calmness despite the stimulation made for a very synergistic mindset at this point. I read that L-theanine may have effects on increasing serotonin as well, though it's still disputed. I'd believe it after experiencing this, but it could have just been from the GABA increasing/NMDA antagonist effects as well. Eventually though, I started to feel a bit tired. This may be due to my sickness, like I said, but I also suspect that the dual nature of L-theanine might make the stimulation more susceptible to reduction from fatigue than the average stimulant. It wasn't really an exhaustion though, just that I had gotten my fill. I headed home and basically relaxed until the effect died out. I'm not totally sure when that was, I didn't much pay attention to it after that.

This was more impressive than I had hoped. It wasn't a very powerful effect, but it wasn't negligible either. I do think though, based on some reports I've read of people getting "drunk" from higher doses, that L-theanine's sedative effect will eventually overpower and probably blunt its mild stimulant psychedelia. This is one probably best used as a compliment to truly psychoactive doses of stronger drugs, as it seems like it could ease your mindset a bit if need be or maybe just smooth out an experience a bit, while still maintaining the same level of hallucinogenic effect. I'll certainly be keeping it on my shelf.
