F-Phenibut (also known as 4-Fluorophenibut, Fluorophenibut, Fluorobut, Baflofen and CGP-11130) is a central nervous system depressant and closely related structural analog of phenibut. F-Phenibut possesses an effect profile similar to phenibut but with a faster onset, significantly increased potency, and shorter total duration.[citation needed] It has recently become available through online research chemical vendors, although little is known about this substance, particularly its potential toxicity and addiction potential.
