Phenibut HCL – Powder, 50 grams

Phenibut HCl (β-phenyl-γ-aminobutyric acid hydrochloride) is a water-soluble GABA derivative with a hydrochloride salt modification, enhancing stability and dissolution in aqueous solutions. It features a phenyl ring substitution, which allows for improved lipophilicity and receptor interaction compared to native GABA. This compound primarily interacts with GABA_B receptors, influencing neurotransmitter modulation and signal transduction. Phenibut HCl undergoes hepatic metabolism through deamination and conjugation, with renal clearance as the primary excretion pathway. The hydrochloride form exhibits higher solubility than its free amino acid counterpart, affecting absorption kinetics and bioavailability.
