Amazon Banned Phenibut! You Can Still Buy It From These Vendors

Phenibut promotes relaxation and calmness

If you search for phenibut on Amazon, you will get many results of various nootropic supplements, but none of them is actually phenibut. Well, don’t bother! Amazon no longer allows the sale of phenibut and a whole bunch of other nootropic drugs, particularly piracetam and its analogues.

Yes, Amazon may be a convenient place where you can source any herbal or natural supplement, but phenibut is just the opposite of that! It is a synthetic chemical that is treated as a drug in some countries, and so it is not considered a dietary supplement according to FDA regulations.

Phenibut is not an approved supplement or medication in the U.S. and worldwide, except in a few countries where it is an approved treatment (Russia and neighboring countries). It is also not a scheduled or regulated substance, which means that consumers can legally purchase it over the counter.

Although Amazon decided not to deal with such drug/supplement products, there are still many other reliable places online that sell phenibut.

Where to Buy Phenibut?

UPDATE: Following recent FDA-issued warnings to manufacturers wrongly labeling phenibut as a dietary supplement, many stores have stopped selling it. As of yet, phenibut is not banned, but it’s not permissible in products labeled as a dietary supplement. It is a synthetic nootropic compound that should be used with caution (more details can be found below).

WARNING: Phenibut can cause dependence if used regularly/daily. You may want to consider one of these natural alternatives for a safer everyday supplement.

The following are nine of the best legit vendors that still carry phenibut. You will also find numerous other nootropics that are banned on Amazon available at the following stores.

Where to Buy Brand Phenibut (Noofen)?

Noofen 250mg capsules (brand phenibut)

Phenibut is sold as a prescription medicine in some parts of the world, particularly Russian and other former Soviet Union countries. It is sold under different brand and generic names in 250mg tablets or capsules.

Noofen (or Noophen) is the most widely used and original brand of phenibut. It is manufactured by the Latvian pharmaceutical company OlainFarm.

Noofen is quite pricey though. A 20-pill pack costs about $35 to $40.

There are other cheaper generic brands manufactured by Russian pharmaceutical companies, such as Anvifen by AnviLab, and Phenibut/Fenibut by Ozon.

Noofen is not carried by U.S. or European nootropics shops, but it can be sourced from some legit Russian vendors. Two of the best online stores that stock noofen and other pharmaceutical-grade phenibut are RUPharma and CosmicNootropic.

Powder vs. Capsules

At most retailers, you can order phenibut in either powder or capsule form. Some users prefer the powder, which allows them to experiment with different dosages, but this should only be done by experienced individuals who are well aware of the potential side effects and risks.

Capsules are generally a safer option than raw powder. It requires some experience and a delicate measuring device to deal with the powder, and it does come with a greater risk of overdosing, abusing and addiction.

If you are a first-time user, it is recommended that you go with the capsules, which are usually available in the dosage range from 250mg to 500mg.

How Does Phenibut Work?

Phenibut is a synthetic derivative and analogue of GABA, which functions as an inhibitory neurotransmitter. The compound is called phenibut as it has two components, a phenyl ring (pheni-) and gamma-aminobutyric acid (GABA), thus the addition of the suffix “-but”.

GABA-based drugs are known to have a calming effect on the brain. They are mainly used to relieve anxiety and promote sedation, relaxation and better sleep. However, GABA on its own is not able to penetrate the blood-brain barrier and thus has limited use. Addition of phenyl ring helps it to cross the blood-brain barrier, and so phenibut is more effective than GABA supplements.

It is essential to understand that not all drugs that act on GABA receptors are similar because GABA receptors are divided into numerous sub-groups. Phenibut acts primarily on GABA-B receptors. It has a weak action on GABA-A receptors.

Phenibut was also found to stimulate dopamine receptors as well as other receptors in the brain. That explains how it may be beneficial for a number of different conditions. Although its primary use is as an anxiolytic and nootropic, it may also help treat sleep disorders, depression, post-traumatic stress, and other conditions.

As a nootropic or cognitive enhancer, phenibut may improve memory and brain function, although it lacks solid clinical evidence that it is beneficial for cognitive functions beyond its anti-anxiety effect.

Phenibut Dosage

Since phenibut is not an approved medicine in most Western countries, there haven’t been many reliable studies that evaluate its optimal dosage.

Based on some of the studies and manufacturer recommendations from countries where phenibut is an approved medicine, and also based on anecdotal evidence and experiences of many nootropics users, the following are some generally accepted guidelines for administering phenibut.

  • The standard dose for adults is 250mg, taken up to three times a day.
  • You may take a single dose of 500-750mg once a day.
  • Do not take more than 1,000mg (1g) per day.
  • It is not recommended to take phenibut daily for more than one month.
  • Cycling phenibut by taking one day (or more) off between doses is recommended, especially for long-term users. This reduces the chance of tolerance build-up and dependence.
  • In case your body builds up tolerance to the dose, i.e. it becomes ineffective, it is recommended to stop taking phenibut for a few days then resume taking it two times a week or less. Do not keep upping the dosage as this can worsen the problem and lead to addiction.
  • If you have been taking phenibut frequently for more than a few weeks, it is not recommended to stop taking it abruptly, otherwise, you may suffer from unpleasant withdrawal symptoms. Instead, you should gradually reduce the dosage for a couple of weeks before completely quitting it.

Safety and Side Effects

Phenibut is rather safe for this class of substances, which explains why unlike other GABA agonists it is not strictly regulated in many countries, though things may differ from country to country.

Despite being an analog of a naturally occurring amino acid and neurotransmitter (GABA), phenibut is produced synthetically and is not considered a natural substance. That means it does not qualify as a dietary supplement, although it is mild on the body.

Normally, small doses of phenibut don’t produce significant side effects, but that differs from one person to another. Some of the potential side effects include the following:

  • Headache
  • Nausea
  • Dizziness
  • Drowsiness

Higher doses of phenibut (over 2,000mg) can lead to serious side effects including the following:

  • Cognitive and motor impairment
  • Poor balance
  • Hangover

Ironically, some users reported experiencing stimulant-like effects when taking phenibut, such as anxiety, agitation and insomnia! In fact, many anti-anxiety drugs have been known to cause anxiety in some cases, especially when taken by healthy individuals.

Women who are pregnant or breastfeeding should not take phenibut.

It is also important not to combine it with alcohol, benzodiazepines, or any other GABA agonist substance. If you take any kind of antidepressant or anti-anxiety medications, then it is highly advised that you consult with your doctor before taking phenibut.

Like many other substances that affect the working of the brain, phenibut can potentially lead to dependence and addiction if abused. It should be used moderately and in small doses.

Natural Alternatives to Phenibut

Although phenibut is a potent anxiety reducer that works for almost everyone, it does come with one major downside: it causes dependence with repeated use.

People who take phenibut on a daily basis will likely suffer from debilitating anxiety, agitation and other withdrawal symptoms when they try to quit phenibut. This is especially a struggle for abusers who take many grams a day of this substance.

While most natural supplements are nowhere near as effective as phenibut, there are several worthy alternatives that have worked for a considerable number of people.

The following are six of the best, evidence-based natural supplements that can be used in place of phenibut for a more relaxed day and restful sleep at night.

I’ve included some reference links to supporting studies — you are free to do your own research.

1. Magnolia Bark Extract

Magnolol and honokiol are two bioactive, organic compounds found in the bark of the magnolia tree. These compounds have been shown to act on GABA(A) receptors and have a mild anxiolytic effect without significant adverse effects. [ref.] [ref.]

2. Magnesium Glycinate

This is an amino acid chelate that consists of magnesium and glycine. Magnesium deficiency has been linked to anxiety and sleep problems, so supplementation may be helpful.

Glycine is an amino acid that functions as an inhibitory neurotransmitter in the central nervous system. Studies show that taking glycine before bedtime can improve sleep quality and reduce daytime fatigue in people suffering from sleep problems. [ref.]

3. Lemon Balm

Lemon balm is an herb in the mint family. The tea, essential oil and extracts of the herb have several medicinal uses. It is a popular sleep aid and natural remedy for anxiety and stress.

Studies have concluded positive results regarding the sedative, anti-anxiety and antidepressant effects of lemon balm. [ref.] [ref.]

4. L-Theanine

L-theanine is an amino acid that is found in some plants, most prominently green tea. It has brain-calming, stress and anxiety-reducing, and sleep-promoting effects. [ref.] [ref.]


Gamma-aminobutyric acid, or GABA, is the natural equivalent for phenibut. GABA is often sold as a dietary supplement to help with anxiety, insomnia and stress.

GABA as a dietary supplement, however, does not cross the blood-brain barrier and so does not have the same potent anxiolytic effect as that of synthetic GABA analogues.

Despite the lack of clinical evidence, many consumers reported experiencing reduction in anxiety and improved sleep when supplementing with GABA.

A 2019 study found that a combination of GABA and L-theanine was synergistically more effective in improving sleep quality than either compound alone. [ref.]

6. Oleamide

Oleamide is an organic compound derived from oleic acid: an omega-9 fatty acid found in olive oil and other fat-rich foods.

Studies found that this compound affects several neurotransmitter systems and has potential sleep-inducing activity. [ref.] [ref.] [ref.]

You can find oleamide powder and capsules at Nootropics Depot — it isn’t a very popular supplement and not many stores carry it. The rest of the supplements can be found at most nutrition stores — I’d recommend PureFormulas.

    1. [UPDATE: LiftMode have resumed selling phenibut.]

      Thanks for the notification, John! Yes, indeed, it looks like LiftMode have removed all phenibut products from their shop.

      It is still offered on their sister website NewMind, which is dedicated to the sale of research chemicals. That website requires an “approved account” before ordering, which could create a major hassle for new customers. They have also been known to arbitrarily suspend customer accounts.

  1. Thanks for the info. It’s a shame Phenibut is becoming difficult to purchase. In Australia it’s now a scheduled substance. I’ve used it a few times a month for sleep for about three years. So much better than pharmaceutical sleeping pills. No groggy hangover. I’ll try the vendors you listed. Appreciated.
