An example of a proper Phenibut dose.

If you're reading this right now, phenibut has probably piqued your interest (and that's probably putting it lightly).

But before you get your feet too wet, we wanted to make sure you had a grasp of all practical aspects of using phenibut.

Hence this - the Ultimate Phenibut Dosage Guide!

And if you don't know what the heck phenibut is at all, then you probably missed out on our main FAQ guide.

If so, we'd recommend spending a few minutes checking that out first.

Otherwise, let's get right into it!

How much phenibut to take

Right off the bat, the generally accepted phenibut dosage is:


For your information, that's equal to 0.75g of Phenibut.

If you're using a scale that is in grams, make sure you're not taking 750g of phenibut because that's 1000 times more than the typical dose!

Important Phenibut Dosage Limits to Follow

No matter how experienced you are with phenibut, there is definitely such a thing as too much.

It is imperative that you never violate the following phenibut dosage limits:

  1. Do not exceed over 1000mg (1g) of Phenibut per dose.

  2. Do not exceed over 2000mg (2g) of Phenibut consumed per day (24-hour period).

Obviously you can do that math and realize that 3 full typical doses already goes over the 24-hour limit.

But don't worry, keep reading through on how long dosages last and you'll also see that 1 or 2 full doses should last the entire day.

How to Take a Phenibut Dose

The Toss-and-Wash Method

This is the easiest (and fastest) method to take phenibut.

  1. Measure out the dose of phenibut onto a piece of paper or your credit card.

  2. Toss the dose into the back of your mouth (be careful not to choke on it).

  3. Take a sip of water and gulp it all down at once.

  4. Drink more water to wash any residual phenibut down.

The Stir-and-Drink Method

This is a fairly common method that takes some extra steps to help you avoid the bitter taste of phenibut.

  1. Measure out the dose of phenibut and pour into a glass of water or other liquid of choice.

  2. Stir the liquid until it phenibut is mixed completely, just like you would do with a powdered drink mix.

  3. Drink the drink in its entirety.

As should be obvious, by replacing water with something sweeter like fruit juice, you can minimize the taste.

Ultimately, the choice is up to you, as long as the proper dosage of phenibut makes it into your digestive tract.

How long will my phenibut dosage typically last?

First off, it is important to note that it will take about 30 minutes before you start to feel the effects of phenibut.

This will give you an idea of when to take phenibut (i.e. 30 minutes before you want to start feeling it).

As a general guideline, before the effects start to wear off significantly, a typical dosage of phenibut will last:

6 hours

However, the effects can easily last the rest of the day, to varying degrees.

This is because phenibut's action on the GABA receptors can linger long after it's been excreted from your kidney.

And obviously, taking over or under the typical dosage will vary the length accordingly.

Having said that, in general, you may start seeing diminishing returns after 5-6 hours.

You can always take another dose, but be sure to follow the hard limits set above (i.e. no more than 2000 g in a single 24-hour period).

Why Should I Dose Phenibut Properly?

Here are three important reasons to dose properly.


Phenibut withdrawal is when you stop taking phenibut too quickly.

When withdrawal happens, you typically experience undesired physical symptoms like nausea, tremors, and restlessness.

Withdrawal can happen with other drugs as well.

For example, the caffine in coffee: If you're used to taking 3 cups a day, and then suddenly stop drinking, then you may experience a caffine withdrawal.


Phenibut Tolerance is when you require larger and larger doses of a drug to get the same level of effects as the first time you took the drug.

This is not good because you're effectively spending more to get the same high / effects, as time goes on.

Maintaining a consistent weekly and daily phenibut dosage can help to prevent a tolerance build-up.

Again, using coffee as an example: once you stop being diligent and start drinking more and more coffee, you become tolerant to the positive effects of coffee.


Overdosing on phenibut, while not as dangerous as other "hard drugs", is still something that must be avoided as much as possible.

Fortunately, this is really easy to do.

If you follow the basic rules of phenibut dosage and take it responsibly, it's extremely unlikely that you will overdose.

Typical Phenibut Dosing Schedule

For those who would like a more real world example of how phenibut can fit into your daily lives, I will explain just how I've scheduled phenibut to fit into my lifestyle over the past 7 years.

Me taking a typical phenibut dosage before class.

When I first started using phenibut, it was primarily for succeeding while studying at Stanford University.

I would use phenibut once a day, getting it to "kick in" right before my first class of the day, with it typically lasting until my last class finished.

I'd take a break on Sunday (my sleep-in day) and on Wednesday (when I typically didn't have many classes).

Saturday was more for recreational use.

I would also take a 2nd dose on Friday nights if I wanted to turn up to certain parties.

And most importantly, I would always be sure to take some phenibut before my final exams, whether the exams were first thing in the morning, or later on in the evening.

Check out a summary of my general phenibut schedule below:

I would be lying if I said phenibut DIDN'T help me make 6-figures.

After graduating from Stanford and starting my six-figure salary job, my new lifestyle afforded me time for working out on Mondays, Wednesdays, and Fridays, and so I started using phenibut accordingly to improve my workouts.

I work in phenibut on Saturdays and Sundays (both of which are recreational days for me now).

And as always, if I ever need to get a better night's rest, or have to present my work to the big bosses at my company (you know, the ones who determine my bonuses and pay raises!), I take phenibut accordingly.

Check out a summary of my general phenibut schedule below:

School Work
Monday Class (1) Workout (1)
Tuesday Class (1) -
Wednesday - Workout (1)
Thursday Class (1) -
Friday Class (1) Workout (1)
Saturday Recreation (1) Recreation (1)
Sunday - Recreation (1)
Other Occasions For some Friday nights, and all final exams For quality sleep, and work presentations

As you can see, phenibut can be worked into any schedule that you have.

And what's really great is that you are always free to work phenibut in whenever you really need it for whatever reason.

Thanks for reading!

Overall, phenibut dosages are not complicated, and as long as you know what to expect when taking phenibut, and always make sure you take it safely, you will reap the many benefits.
