Description
4F-Phenibut-HCl Overview
4-Fluorophenibut HCl is a synthetic research compound and a fluorinated derivative of phenibut. The addition of a fluorine atom differentiates it from phenibut and may influence receptor interactions and metabolic stability, although further studies are required to fully understand its properties.
