Phenibut HCL (250mg/capsule), 60 Capsules

Phenibut HCl (β-phenyl-γ-aminobutyric acid hydrochloride) is a hydrophilic GABA derivative featuring a hydrochloride salt modification, which enhances solubility and stability in aqueous environments. The phenyl substitution allows for increased lipophilicity and receptor affinity, distinguishing it from native GABA. This compound primarily interacts with GABA_B receptors, modulating neurotransmitter signaling pathways. It undergoes hepatic metabolism via deamination and conjugation, with renal clearance as the primary excretion route. The capsule formulation ensures precise dosing and controlled delivery for research applications.
