Phenibut HCL (250mg/capsule), 60 Capsules

A hydrophilic GABA derivative with a hydrochloride salt modification, phenibut HCl (β-phenyl-γ-aminobutyric acid hydrochloride) improves solubility and stability in various conditions. It differs from native GABA due to the phenyl substitution, which increases lipophilicity and receptor affinity. This substance mainly modifies neurotransmitter signaling pathways by interacting with GABA_B receptors. Renal clearance is the main method of excretion, and it is metabolized by the liver by conjugation and deamination. For research purposes, the capsule formulation guarantees accurate dosing and regulated distribution.
