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.

    Very good supplement for anxiety. Be very careful. Only only take once or twice a week.

    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.

    Best product I have found BY FAR!!! NO MORE BENZOS!!! This site offers the absolute CHEAPEST and fastest delivery! Greatest for social anxiety. I can actually live my life!! Seriously, not even the highest dose of xanax could get me out to a social function! This product from Hard R has no come down, unlike other product from other sites. I get a restful, full nights sleep and good dreams! :) Better mood, concentration and way less anxiety over all. All the benefits of xanax and adderall with virtually no side effects and lasts for about 36 hours total, before all effects wear off and a mild head ache begins. Head aches from this company's product could be easily cured with alieve, IF, you even get a head ache ..Its really dependent upon dosage. My dose is actually about 700 mgs for three days straight, then 3 days rest, However, i do have a slight tolerance
    For xanax. All other sites that you order from, you WILL, i repeat, you will, will get a head ache by the end of the day, not with this stuff though idk what it is about hard rhino, i really dont, its amazing! It is recommened you only take it 2 times a week bc of the headache side effect and tolerance ect..but i found a way that works better for me ONLY FROM THIS SITE! again, idk what it is about this particular company's product, maybe they have the purest stuff.. but i dont get a bad head ache with hard rhino stuff, if i even get a headache at all! Its wonderful! I am so happy with Hard Rhino! Best best best phenibut, i love it!! and my friends and family do as well! Hope this company keeps selling this stuff for a long long time! DEFINITELY reccomend 10000%
