About Phenibut
Phenibut is a GABA-derived calming compound (a small molecule, not a peptide) developed in the Soviet Union and sourced for anxiety and sleep research. It ships as a powder or capsules.
Its reported half-life is ~5 hours, which is the main reason the community cadence above looks the way it does. Registered as a prescription anxiolytic in Russia, Belarus, Latvia, and Ukraine.
How to Read the Phenibut Capsules Comparison
- Price per milligram — Every Phenibut Capsules listing is normalized to $0.001/mg-style unit pricing, so a small cheap bottle cannot hide a worse real cost than a larger one.
- COA status and purity — The 2 COA-backed Phenibut Capsules listings show assayed purity and test date so quality is a number, not a claim.
- Stock status — Live in-stock state for each Phenibut Capsules listing, refreshed on a recurring basis.
Reading Phenibut Capsule Listings
Capsule listings are ranked on total Phenibut per bottle — capsule count multiplied by milligrams per capsule — rather than on bottle price, because a cheaper bottle with fewer or weaker capsules routinely costs more per milligram. A capsule COA should test the finished capsule rather than the raw powder, and it should cover the exact capsule strength on sale.
Oral capsule formats differ from injectable vials in route of administration and bioavailability, so a Phenibut protocol written for one format does not transfer to the other. Confirm the vendor's COA covers the capsule product specifically.
