4f-Phenibut (β-Phenyl-GABA, β-phenyl-γ-aminobutyric acid, Noofen, Citrocard) is an analogue of the inhibitory neurotransmitter GABA. The addition of a phenyl ring allows 4f-Phenibut to cross the blood-brain barrier (BBB). Neurohackers prefer 4f-Phenibut when the goal is to raise GABA levels in the brain because GABA as a supplement cannot cross the BBB.
