Modafinil is a performance enhancing cognitive medication or “Smart Drug”.

Students and corporate workers use it regularly for help to tackle tougher projects by increasing workflow efficiency.

When prescribing modafinil doctors provide comprehensive instructions on the dosages for their particular use.

However, when ordering online people are sometimes left clueless about the best dose for their medication.

Today we will explore the common dosages amid the most prominent modafinil products from online vendors such as Dr Modafinil and Afinil Express.

We will go through the amount you should take depending on your reasons and help to highlight a basic dosage schedule that will get the best possible results from the medications.

There are two different types of Modafinil.

To talk about doses, we must first understand the two different types available; armodafinil and modafinil.

They both share the modafinil compound as the active ingredient but do have differences.

Chemists consider modafinil a “racemic” compound. Meaning the modafinil contains two isomers of the same compound. Isomers are variations of an identical chemical. The two isomers are practically identical but are mirror images of one another.

Armodafinil is an “enantiopure” compound- meaning it contains just one type of isomer- known as the R- isomer.

The R- isomer is considered to be stronger than the S- isomer, meaning the effects of armodafinil are slightly stronger than modafinil.

The differences in dosages between Modafinil and Armodafinil

The first difference is in doses between modafinil and armodafinil.

For modafinil, the dosage is 200 mg, while an equivalent armodafinil dose is lower at 150 mg.

At this dose, armodafinil is more intense than modafinil.

Where can you purchase Modafinil online?

Many online stores sell modafinil. However, because of the low standard of regulations in the industry, the market is full of vendors lacking in quality.

Some exceptions offer higher quality armodafinil and modafinil at quite competitive rates.

Why do we prefer to purchase modafinil online?

A prescription is not needed in online purchases of modafinil. Legal grey areas have allowed online sellers to provide you with modafinil without a prescription. This saves the buying wall you can find yourself at if you can’t get a prescription. The grey area is created because modafinil is not illegal, just the sale of it. Some parts of the world do allow the legal sale of modafinil which is where most sellers operate.

Also, why pay for shipping when you can get free shipping from many online sellers. Most ship from India, so free shipping is something to be excited about.

Often online sellers can sell ‘generic’ modafinil at much lower prices than the brand name versions that are sold in pharmacies. The generic modafinil is almost identical to the brand name versions and goes through the same quality testing.

How much should I take?

Depending on if you’re using armodafinil or modafinil the dose may be different.

We will now break down the philosophy behind some of the most common reasons for people taking the medications.

Modafinil for cognitive enhancement

The dosage range for the benefits of modafinil on cognitive enhancement is between 50 and 400 mg depending on motivation.

For Narcolepsy and ADHD

150 mg of armodafinil or 200 mg of modafinil is the average dose prescribed for the treatment of narcolepsy and ADHD. In more severe cases it can be as high as 250 mg for armodafinil and 500 mg for modafinil.

Patients rarely take days off medication for narcolepsy as they see a significant increase in symptoms. The patient can decide on this depending on how bad they believe their symptoms to be.
One to two days off a week are taken by patients medicating for ADHD to prevent possible long-term side-effects.

Some other factors that can change dosage are how reactive they are to the drugs, the size of the patient and the frequency of consumption.

Smaller doses for Cognitive Enhancement 50 mg

People may prefer to take modafinil in smaller doses. It is the safest option for long time use but creates the weakest initial effects.

A dose that is 50 mg or less is a microdose. This means that the dose is considered below the therapeutic standard dose.

Despite offering less noticeable effects than higher doses microdosing can provide benefits over more extended periods.

A lot of people use microdosing as a caffeine replacement that helps them to feel more awake in the mornings. It helps to create a stimulating but gentle wakefulness effect just 30-45 minutes after taking it.

Modafinil usually doesn’t come in 50 mg tablets.

To get that dose a 100 mg tablet would need to be broken into two, or a 200 mg dose into quarters.

Breaking the 100 mg tablet is much more comfortable, and a crease is even included to help consumers split the pill more easily.

Mashing tablets into a powder and splitting it into portions is common. The powder is divided into for equal parts and can then be blended into a smoothie. This method massively lowers the time taken for the modafinil to enter the bloodstream. It allows efficient control of smaller doses.

Armodafinil equivalent dosage is 50 mg in this range but may be slightly stronger in its effects.

You should use 50 mg modafinil doses when:

  • You are starting and need to test effects
  • You are sensitive to the drug
  • You want the smallest chance of side-effects
  • You plan on long-term use

Doses for Cognitive Enhancement 200 mg

This is the most popular dosage and most common dosage type found online.

The dose of Modpure, Waklert and Modalert usually 200 mg per tablet.

This dosage also has the most scientific research behind it.

Armodafinil equivalent dosage is 150 mg and is supplied in the generic versions of Modvigil and Artvigil.

Benefits of a 200 mg modafinil dose

  • The easiest dosage to take
  • Has well-documented effects on cognition
  • The research behind it is fruitful
  • It is the most common online

Doses for Cognitive Enhancement 400 mg

Some people may require larger doses of modafinil. The highest dose considered safe is 400 mg. This is because anything over 400 mg increases the risk of side effects dramatically.

A dose this large is used for larger individuals or long-time users with tolerance to modafinil.

It is not recommended for people just starting to take modafinil. Its side effects include insomnia, anxiety and more. If you ever did wish to try this dose, you should always build it up from smaller doses either 50 or 100 mg regardless of your size.

It is done to make sure you are not sensitive or allergic to the drug.

Armodafinil equivalent dose is 250 mg. Many tablets are supplied in doses of 150 mg, making a 300 mg easier to achieve. This will be stronger than the equivalent 400 mg of modafinil.

What are the benefits of a 400 mg modafinil dose?

People with larger builds benefit

  • Better for short-term usage
  • It has the most substantial effects within a safe dosage range
  • People with a faster than average drug metabolism can benefit

Side Effects of Modafinil

Some side effects associated with modafinil include headaches, digestive discomfort, insomnia, dry mouth, and a low appetite.

The higher the modafinil dose, the more likely these side effects are to occur.

While the 400 mg dose regularly causes side effects the 50 mg dose rarely does.

These side effects can be reduced or avoided by avoiding other stimulants such as tea or coffee and taking it earlier in the day. And also by trying some of the Ten Best Modafinil Stacks we outlined in a previous article.

Water is essential in reducing side effects. 2 to 3 litres of water a day should be consumed.

When should you visit a doctor?

Rarer more severe side effects have been reported on all doses,

If ever experiencing difficulty breathing, dizziness, skin reactions, hallucinations, or hysteria you should immediately visit a doctor.

Dosage Schedule for New Users

If you are starting a medication or supplement, you should start with a smaller dose and build to a higher dose over time. This assures you can metabolise and are not allergic to the drug, and so can eliminate it from your body if needed.

The liver metabolises almost every drug that enters the body. Enzymes are used to break down the chemicals. A specific gene known as CYP450 isoenzymes codes them.

CYP450 genes are unique for everyone, with some people able to break down chemicals more effectively than others.

An example of this is with coffee where some people require more than others to stay alert. They are unable to break the caffeine in the coffee down as the CYP450 polymorphisms they have had from birth are not as efficient.

This is the same for modafinil which is why it is usually best to make sure the drug is problem free before taking higher doses.

Difficulty metabolising modafinil means the effects will last longer.

Also, if it is taken every day, your bloodstream can start to build up concentrations over time.

Dosage Schedule for New Modafinil Users

Week Dose If Side Effects
1 50 mg Modafinil might not be for you
2 100 mg Go back to 50 mg
3 200 mg Try 150 mg
4 300 mg Try 250 mg
5 350 mg Go back to 300 mg
6 400 mg Go back to 350 mg

As medication modafinil can be very useful in increasing productivity. For school or work, it can help people gain a lead on their peers.

The success of the drug is crucial to the correct dosage due to possible side effects.

Starting at 50 mg or 100 mg is recommended for the first days. Modafinil (Modvigil and Modalert) has a standard dosage of 100 to 400 mg per day. Armodafinil (Artvigil and Waklert) has an equivalent dose of 50 to 250 mg per day.

Always make sure the consumption of water and food is a focus throughout the day to avoid any potential side effects.


I am writing this for Dr Modafinil, and this guide was done before my discovery of ModPure and their capsules. I suffer no side effects from modafinil, so the ModPure 100mg and ModPure 200mg capsules suited me fine.

I would add that if you do need to split into 50mg increments then if anything, these Modpure capsules would be more natural to break as there is no need to crush them and there is no binding agent, the Modafinil is the purest I have seen.

There is no Armodafinil yet, but Chris said that would be soon! If the Modafinil is anything to go by then, that will be brilliant also.

I do generally prefer tablets over capsules, in future though I will be using Modpure now as the quality is just brilliant!
