What is Phenibut?

Phenibut is a GABA derivative that can exist as a free amino acid (FAA) or as a salt (HCL). Phenibut HCL is the salt variety, which is why it is crystalline in texture. There are a few key differences between Phenibut FAA and Phenibut HCL.

HCL vs. FAA

Individuals may notice that the FAA form is more "fluffy" than the HCL form. However, the FAA form is more expensive and is not conducive for supplementation. Due to its powdery texture, it is difficult to dissolve in a beverage or put in capsules.

The HCL form is easy to dissolve or put in capsules. It is also more cost effective than the FAA. The HCL compound has a less pleasant taste than the FAA form, but, since you can buy this in capsule form, this is a non-issue.

How Does It Work?

Unlike GABA, Phenibut HCL can cross the blood-brain barrier (BBB). [1] This is due to the addition of a phenyl ring to its basic structure. [1] Individuals take this product because it promotes relaxation and has other cognitive benefits. [1,2] It is a GABAB receptor agonist which means it can support a healthy mood as well. [3]

Phenibut Effects

The primary reason individuals take Phenibut is for its ability to promote relaxation.* However, that is not the only benefit. Aside from its potential as a nootropic, this product can also support a healthy mood and promote sleep.*

Promoting Relaxation

Phenibut is able to promote relaxation without drowsiness. [4] Because of this, Russian cosmonauts often used Phenibut. Phenibut allowed them to work in less than ideal conditions without succumbing to the effects of mood imbalance. [4]

Nootropic Benefits

There is some debate as to whether this product is a true nootropic. However, there is some evidence of its ability to enhance cognition.* In passive avoidance tasks, Phenibut showed enhanced learning and memory. [1] It also enhanced the performance of mice during swimming and rotating rod tests. [1].

Mood

During a forced swim test, Phenibut reduced immobility time to a significant degree. [3] Scientists use forced swim tests to measure activity related to enhanced mood. [5, 6] 

Sleep Quality

This compound provides sleep benefits as well.* One study suggests this is because it may activate dopaminergic processes which cause sedation. [1]

Warnings:

Individuals should not take this product on a daily basis. Tolerance develops rapidly with repeated use. [7] When taken in excessive frequency, Phenibut can cause withdrawal symptoms upon cessation of use. [7] To avoid this, follow proper dosing instructions. Individuals taking MAOIs should not take this product. [7] Do not take this powder with alcohol. [7]

Recommended Dosage

Individuals should start with 250mg. Some individuals use larger doses, but you should never exceed 1.5g. Individuals should cycle Phenibut.

Synonyms: Fenibut, Phenybut, Beta-Phenyl-GABA

FAQs

Do textures differ from lot to lot?

Due to different suppliers and milling processes, there may be a difference in powder texture from one lot to the next. Some lots may be crystallized and others may have a finer consistency. Though the mesh sizes of the powder may differ, the product is still Phenibut HCL and mesh size does not affect potency.

What are some products that go well with Phenibut

How do I take Phenibut?

To promote mood and sociability:

The recommended dosage of Phenibut is 250mg. It is best to start with the lowest effective dose to assess tolerance.

Sleep:

Do not take Phenibut more than 2-3 times per week to avoid developing a tolerance.

Curated Reviews

"Powder City's Phenibut is the best I've used, and I've been using various brands for a LONG time. It's also very consistent from order to order, delivering consistent relaxation "on demand",and puts you in a fantastic mood. As for the price? By FAR, the lowest cost on the internet (in any quantity) but especially 1 kilo. You won't find it for less than $200/kilo, with one planet asking for $305.95/kilo! Great product, at a GREAT price... "- Rob R.

"I tried Phenibut HCL on one of the weekend sales from Powder City. I am looking to produce more GABA at night without directly worrying about taking GABA straight and very little of it crossing the blood barrier. I take Phenibut 3 nights per week to avoid saturation point dosage and maintain the effectiveness. So far, I can tell it is a comfortable addition to my L-Dopa (from Mucuna Pruriens, 98%) and natural growth hormone pulses. I will be back for more as Powder City is turning out to be a wonderful supplier. Thank you!"- Derek H.

"I must say I am very impressed with this supplement. Certainly has very noticeable effects when taken. Have found taking a smaller dose along with a few other supplements (caffeine, theanine, hordenine) seem to offer really good results for calm, focused, energy for a good 5 hours. Certainly helps with just relaxing and sleeping with larger doses if that’s your purpose. Of course have to be careful with avoiding building up a tolerance. Overall I have found this to be a great supplement and it has improved my overall mood day to day. Would certainly recommend purchasing form PC given their product has been great each time I've purchased and their shipping is extremely quick."- John F.

"I'm not big on reviews, but for this company and this product, I felt obligated. Why do I feel obligated? I ordered this on Sunday, knowing it wouldn't ship until the next day. Monday comes and I get an email saying it shipped. The phenibut arrived in my mailbox the very next day. I didn't click 1 or 2 day shipping -- just regular mail. That alone merits 5 stars. It's customer service like that that'll ensure I come back again - and I will. Now a little about the phenibut itself. It came packed very professional and secure in a heat resistant envelope. I think its heat resistant, anyway. Appears to be. There's a tiny scoop included that was in a small plastic bag attached to the bigger bag of phenibut. Very convenient, I must add. I was dreading digging through the phenibut to get the scoop out. So that was nice. The phenibut quality is great. This is a potent stuff, so if you're new to it, please use with caution and listen to advice from others who have used it before. I am more than pleased with my phenibut purchase from powder city. I would recommend this product, and I would also recommend powder city. Thanks!!! "- Thomas.

"Best I have ever tried. I have purchased 500 grams from a previous bulk supplement company and thought that was good until they were out of stock and stumbled across powder city. Powder city phenibut takes 1/2 the dosage to get the same effect as my previous vendor. Not only that it was shipped immediately which included a thank-you card with my purchase. Something seemingly small like a thsnk you card is appreciated and goes a long way in my mind. The product is spectacular and so is the service. I give it a five-star rating. I'll be shopping here more for my nootropic needs."- Mike

"This stuff does get you the desired effect of some confidence boost and such throughout the day, although it must be noted that it does taste rather awful, so if youre going to consistently use, maybe invest in a capsule mechanism. But with that if youre planning on consistent use it should be noted that it should really, only be used maybe twice a week and if that if you’re getting 3-4 days between modest doses, and youll have to really use your personal discretion on that portion of it because depending on how much you weigh, and the tolerance to it, that can change quickly. This being said, as always ramp up, and don’t just go for one large dose right at the git go because thats gonna be a one-way ticket to headaches and dizziness for hours to come. Also it takes a while to kick in so do not, take more while you’re waiting on the come up to begin."- Anthony Z.

"I found myself more alert with exceptional concentration involving mental activities at smaller doses, which I prefer. I take it first thing in the morning and am fine all day. I sometimes take a little more later on. I do three days in a row with one-day break. I drink absolutely no alcohol and use no drugs whatsoever. A larger dose, after the initial energizing effects, did give me an uninterrupted night's sleep and I had to take a nap the next day. I hope my honest review helps someone else decide if Phenibut is right for them. It is helping me. I got free shipping and it arrived in a few days."- Lynne F.

"I placed my order of Phenibut late at night and had a confirmation the next morning and my order also went out that morning. This is my first experience with Phenibut and it didn't disappoint. I was skeptical but the product is probably as good as the best reviews I've read. I also left my wife a dose in the fridge when I went to the gym. Got back and she's talking up a storm and says she feels great. This product is so good I can see the abuse potential so please be sure to cycle it like youre supposed to and don't use day in day out. I want to order kratom as well and maybe try that on my off days of phenibut. I certainly recommend Powder City as their communication, shipping, and quality is top notch. This was my first order and I stumbled across this site while researching phenibut."- Chris M.

"Adding Phenibut to my routine on important days has been phenomenal. Powder city's quality is amazing. It has a calming, non-drowsy effect that lasts all day. Even more impressive about phenibut is its sleep enhancing qualities. The night before a busy day, I'll use the recommended dosage of phenibut 3 hours before bedtime. Not only do I enjoy an extremely relaxing evening, but I then sleep like I haven't since I was a baby! 8 hours straight of sleep is something I haven't enjoyed in years until I found phenibut and Powder City. Just be careful not to exceed recommended dosage as you may still feel tired in the morning. If you take the recommended dosage, you will sleep like you never have before. Thank you Powder City! "- JC
