Background of Phenibut

Important Information, Benefits, Effects, and Important Facts

Phenibut has been used significantly in Russia since the 1960s as a nootropic agent for supporting healthy stress levels, for promoting feelings of well-being and a positive, sociable mood, as well as to promote good restful sleep. Phenibut acts primarily as a GABA-B agonist and, in larger amounts, may also play a role in activating some GABA-A receptors. It also acts as a potent CA2+ channel blocker. This sets it apart from most GABA-agonists (like alcohol and benzodiazepines), which are known for their sedative-like effects.


Phenibut is not a dietary supplement and has relatively little research available in human subjects. It has the potential for tolerance build-up, abuse, overdose, and withdrawal symptoms. MUST BE HANDLED WITH CARE.

We offer Phenibut in either powder or capsule form.  You will receive your product in an FDA food-grade sealed mylar pouch with a 1cc measuring scoop for your convenience.

Phenibut is a calming, mood lifting, sociability enhancing, and potentially (in low serving sizes) nootropic supplement that acts as a GABA-B agonist to ease stress and support a positive, social mood. The primary benefits of Phenibut use also include pain-reduction, easing muscle tension and stress, and promotion of deep, restful sleep.The recommended serving size of Phenibut is 500 - 2000mg per day, in up to two to three separate servings, depending on the desired effect. 

Phenibut should not be consumed in amounts exceeding 4 grams total per week, and should NEVER be taken in higher amounts on consecutive days due to rapid development of tolerance to the benefits. Phenibut is one of the most effective and powerful amino acid supplements available. Side effects of higher or excessive Phenibut doses may include dizziness, vertigo, nausea and lethargy. Withdrawal symptoms including anxiety, depression, and insomnia can occur after continuous or excessive use. Phenibut requires careful, disciplined and responsible cycling and limited consumption in order to maximize benefits and minimize potential drawbacks.
