Ingredient List: Phenibut HCl Powder

Beta-Ρhenyl-Gamma-Aminobutyric acid, better known as Phenibut or less commonly Fenibut or Ρhenybut, is a derivative of the naturally occurring inhibitory neurotransmitter Gamma-Aminobutyric acid (GABA). The addition of a Ρhenyl ring allows Phenibut to cross the blood brain barrier. It is suggested that the GABA system is found in the hippocampus, an area of the brain which has been implicated in memory formation. GABA has also been noted to play a role in the sleep cycle as it one of the most abundant neurotransmitters, which may promote a relaxing effect. Our form of Ρhenibut is HCl (hydrogen chloride), which makes it a stable powder form.

    Great quality, and inexpensive. When other vendors increase their prices, Hard Rhino doesn't. When other vendors have lower quality, Hard Rhino still has great quality.
