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)



Anecdotal and scientific evidence suggests the benefits of Phenibut HCL usage includes:

1) Enhanced sociability.

2) Stress relief.

3) Anxiety relief.

4) Restful sleep.

5) Improved mood.

6) Increased focus.

7) Relaxation.



Take 1-2 servings [1-4 Capsules] 1-4 times daily. Do NOT exceed 4 servings [1,000mg or 4 Capsules] per dosage. Do NOT exceed 8 servings [2000mg or 8 Capsules]  per day. Do NOT exceed 16 servings [4000mg or 16 Capsules] per week. Take a rest period of 2-3 days after 2-3 days of continuous usage.

If Phenibut HCL Capsules are not properly used, there is the chance of misuse or abuse. This may also increase the negative side effects instead of the positive effects. The negative side effects of Phenibut HCL include nausea, headache, stomach pain, withdrawal symptoms and more. You may also become dependent on the substance. These tend to be seen more with the misuse or abuse of this product. Do not misuse or abuse Phenibut HCL. You should also never mix phenibut and alcohol as these have a similar effect on the body, and mixing the two can be very toxic or deadly. Proper precautions should be taken before handling phenibut, which includes talking with a qualified professional.

    I decided to try Phenibut for anxiety and insomnia. It really does work and I am so grateful to be able to buy it here for a fair price. It is a great product for chronic pain, chronic fatigue, anxiety, general stress, depression, insomnia, and even PTSD. THANK YOU!!!

    First of all, this is a chemical I've been using for years as part of my workout regimen. I have more energy (I say this as a daily coffee/b12/b6 vitamin user), am more confident in my abilities, and more relaxed at the gym. My wife uses it a couple times a week for sleep or stage fright. I have friends who have had relief from persistent PTSD using only a micro dose (please have a calibrated scale and do your research). It is a wonderful supplement. Read the directions though, overdoing it will ruin what can be astonishing benefits. The company carefully explains this, but I worry people fail to read packaging.

    Second of all, this product comes with everything you'd expect. Not only is it lab certified for purity- but it's nicely branded, arrives on or before estimated times, and is backed by customer service that responded to me within 10min. Before I purchased anything.

    The supplement quality Zach brings is what is promised. It feels equivalent to any lab tested Phenibut I've encountered. Great company. Even if you have a regular supplier you enjoy, I would advise giving ZAS a shot, and not just because the acronym is fun to type, haha.

    Not as good as the powderived by a long shot

    Posted by Alli on Dec 10th 2017

    I got the caps in yesterday for convenience and noticed a difference when I mixed them in with some water. Hard to mix, odd taste. My normal dosage did not work for my insomnia, I broke my own rule and took more, which allowed me to sleep just a few hours, but when I got up, I was exhausted- I'd call it a phenibut hangover. I've tried many different brands and was pleased with the powder but will not order the caps again.

    I’m new to Phenibut and believe it may take a bit to adjust to dosage but I would highly recommend this company for buying what seem like quality products! The owner is very responsive and has been very helpful!
