Summary
4-Fluorophenibut is a fluorinated analog of phenibut, reported to be 5-10 times more potent with faster onset and shorter duration. It acts primarily as a GABA-B receptor agonist with possible voltage-gated calcium channel activity. Users report more pronounced physical effects and euphoria compared to phenibut, with a correspondingly higher risk of dependence and compulsive redosing. Tolerance develops rapidly with daily use. Withdrawal can be dangerous and may include severe anxiety, insomnia, and potentially seizures due to possible GABA-A activity.
