Phenibut (β-phenyl-GABA) is a non-peptide small-molecule GABA analogue that acts primarily as a GABA-B receptor agonist, with weaker GABA-A activity and secondary binding to the α2-δ subunit of voltage-dependent calcium channels. Developed and approved in Russia/former Soviet states since the 1960s for anxiety, sleep disturbance, and related conditions, it is not FDA-approved and is not a lawful dietary ingredient in the United States; FDA has issued warning letters to supplement marketers. Phenibut is widely documented in case literature for dependence, severe withdrawal syndromes (including delirium and seizures), and is sold in a gray market as an unregulated nootropic despite regulatory action.

How are Phenibut prices verified on Disclosed Labs?
Every listed vendor holds a Grade C or better trust score, computed independently from lab Certificates of Analysis — not from payments or sponsorships. Prices are scraped and fact-checked daily. Vendors cannot pay to improve their ranking.
Check formulation: Lyophilized powder requires reconstitution before use. Pre-mixed solutions are more convenient but may have a shorter shelf life and higher prices.
Compare per-mg cost: Different strengths and quantities make direct price comparison difficult. Calculate the per-milligram cost to find the true best value.
Verify COAs: Look for vendors that publish per-batch Certificates of Analysis from named, accredited labs. Use the Full safety panel filter to require endotoxin, sterility, and heavy-metals testing on the current batch — not just HPLC purity.
No registered interventional clinical trials were found on ClinicalTrials.gov (API totalCount=0). Phenibut was developed and used clinically in Russia beginning in the 1960s for anxiety, sleep disturbance, peri-operative sedation, asthenia, PTSD, stuttering, and vestibular disorders, reflecting legacy regulatory approval abroad rather than FDA-reviewed randomized controlled trial data. Human data otherwise consists of case reports and case series documenting toxicity, dependence, and withdrawal rather than controlled efficacy trials. Rodent studies showed decreased neuronal activation in hippocampus and neocortex, increased neuronal synchronization, and reduced behavioral reactivity/anxiety; rat brain membrane binding studies confirmed R-phenibut binding to the α2-δ subunit of voltage-dependent calcium channels and gabapentin-like anti-nociceptive effects in rodent pain models.
