L-Theanine (γ-glutamylethylamide) is a naturally occurring non-protein amino acid investigated for its effects on glutamatergic, GABAergic, and monoaminergic signaling pathways. Experimental research has examined interactions with glutamate receptor systems, including NMDA- and AMPA-associated signaling mechanisms, as well as modulation of glutamate transporter activity. L-Theanine is also studied for its influence on GABA-related neurotransmission, intracellular signaling, and neurotransmitter regulatory networks. Research applications include glutamatergic signaling, receptor pharmacology, neurotransmitter modulation, electrophysiological activity, signal transduction, and comparative amino acid neuropharmacology. For research use only—not for human consumption.

The 100 gram container arrived well packed and clearly labeled. Shipping took a few days longer than expected, but the product itself arrived in good condition.
Freddy (verified owner) –
Presentation was simple and clean, which I liked. Tracking could have updated a little faster, though the packaging was secure when the order arrived.
