Why Should You Buy Phenibut Powder? What are the Benefits?:

Phenibut was first discovered in Russia in the 1960s. It has many scientific studies to back up its claims. In fact, it's used in Russia as a prescription for various ailments. (CNS Drug Rev. 2001 Winter)

Phenibut is commonly used for:

1) Enhanced sociability.

2) Stress relief.

3) Anxiety relief.

4) Depression relief.

5) Insomnia relief and promoting restful sleep.

6) Enhanced mood.

7) Improved concentration and focus.

8) Relaxation.

According to WebMD, "Phenibut is used for anxiety, fear, trouble sleeping (insomnia), tension, stress, fatigue, post-traumatic stress disorder (PTSD), depressionalcoholism, and irregular heartbeat. It is also used for improving memory, learning, and thinking." 

Will It taste bad?:

Phenibut powder has a natural sour taste to it, kind of like a sour candy. If mixed with 8oz of water, it's virtually tasteless. This product is a super-fine powder and mixes very well with water.


The included .625cc scoop measures approximately 500mg. The servings size is 250 mg, or about one-half of a scoop. The amount will vary. The scoop is meant to be used as a guide only. A scale is needed to accurately measure this product. 

Phenibut Dosage:

According to independent sources, you should consume 250mg(~one-half scoop) to 500mg(~1 scoop) one to four times per day. According to independent sources, this amount should not go over 1,000mg at one time and not go over 2,000mg per day. Doing so could increase the negative side effects and decrease the positive effects. In addition, independent sources suggests that you should not use phenibut more than 2-3 times per week, and should take a 2-3 day break after 2 days of use. Do not consume more than 4,000 milligrams in a single week. A scale is required for accurate measuring. The scoop provided is an approximate measurement and will vary.

    Great Price - Top Quality - Arrived in two days.

    Posted by Ken D on Jun 26th 2018

    It's the real deal and a great price on 200g. I buy empty caps from Amazon and fill them myself. The math on that is basically 780 250mg caps for about $50. You'll need to buy something in addition to the 200g of phenibut to qualify for free shipping here, same principle with Amazon.

    The reason for 780 instead of 800 caps is spillage.

    Best quality, best price,fast international delivery.

    Posted by Russian Ivan on Jun 5th 2018

    After the ban on the sale of Phenibut without a prescription in Russia, this site has become a real salvation!
    The price is the same as the Russian medium-quality Phenibut in the pharmacy.
    Quality is much better, delivery is fast.

    Ive been taking phenibut for bover 2years now and have used 5 diffrent vendors in the past for my phenibut and my last batch from my main vendor i used to get Phenibut from was really bad it didnt feel right so i was browsing around reddit and came across zach so i was like well lets give this a shot ordered some phenibut it got here in like 4 days really fast compared to my normal vendor.Zach's customer service response time is really fast and he is a really cool guy awnsered all of my questions and made me feel like he was a friend or someone ive known for years.As for his phenibut today was the first day of taking it and i gotta say A+++ Potent as hell i took 300mg less of my normal dose and it was like i was taking my normal dose.I wont put my dose on here because YMMV. and i gotta say he has a customer for life with me i will be buying more products from this dude in the future. If you ever have questions hes always here to help just shoot him a text he anwsers fast.Ive already told all my friends to order from zach had one coworker try it for the first time today and he ordered on his lunch break...A+ zach keep up the good work!!!!!!!!!!!!!!!!
