Modafinil is a cognitive-enhancing substance that is popular with students and corporate workers due to the alertness it provides.

This substance is typically prescribed by doctors for serious sleep conditions, such as narcolepsy or sleep apnea. When you are prescribed modafinil the doctor will provide a strict instruction of dosage that you must take for your specific purpose.

However, those who are purchasing modafinil for the off-label uses do not have any instructions. In these cases, the dosage is a guessing game which can potentially put you at risk if you take too much.

The dosage of modafinil that you need will differ depending on your purpose for taking the substance and therefore how much you actually need.

Types Of Modafinil


In order to get a good understanding of the correct dosage, we need to first look into the kinds of modafinil that are available.

There are two types of this nootropic substance; modafinil and armodafinil. Both of these substances contain the modafinil compound as the active ingredient, but there are other elements present that make them different.

Modafinil –  is considered to be a ‘racemic’ due to the fact it contains two isomers of the same compound. Isomers are essentially different variations of the same compound – they are almost identical except that they are the mirror image of each other as they are reversed.

Armodafinil –  is considered to be an ‘enantiopure’ due to the fact it only contains one kind of isomer. Armodafinil contains the R-isomer, which is considered to be slightly stronger than the S-isomer which is present in modafinil. This means that armodafinil is stronger than modafinil.

Although both of these substances can offer the same benefits, such as alertness and increased productivity, armodafinil is stronger meaning this may be more useful for your needs.

As armodafinil is stronger than modafinil, the dosage of the two is going to be different.

Dosage Of Modafinil And Armodafinil

As armodafinil is stronger than modafinil, due to the presence of different isomers, the dosage for the two is going to be different.

You do not need as much of armodafinil to experience the same effects as modafinil. Typically, the standard dosage of modafinil is 200mg whereas the standard for armodafinil is 150mg.

Even at this lower dosage, armodafinil is considered to be more intense than modafinil.

Due to the fact that armodafinil is stronger and can deliver more intense benefits than modafinil, the highest dosage is significantly lower than you may expect. Typically, the highest dosage of modafinil can be 400mg, although this shouldn’t be taken at once.

Armodafinil, on the other hand, as it is stronger should only be taken in dosages up to 250mg.

This is because armodafinil can deliver faster and more intense effects when compared to modafinil, so a smaller dosage is just as effective.

Where To Buy Modafinil And Armodafinil?

Now that you understand how modafinil and armodafinil work, it is likely that you will want to get your hands on either substance.

The only issue with purchasing any kind of substance online is the risk of low-quality products and wasting money. The market is saturated with low-quality vendors, but if you look hard enough, you will find amazing pharmacists online.

These pharmacists will sell and ship high-quality modafinil to your location without the risk of damage or restriction from customs.

There are such great benefits to purchasing modafinil or armodafinil online, such as:

  • Free Shipping

Some online vendors will ship modafinil or armodafinil for free to your location, which is a great way to save money.

Most online vendors keep their stock in India which means you would have to face heavy shipping rates without this great offer.

  • No Prescription Required

Getting your hands on modafinil or armodafinil in your country, unless you are located in India, can be incredibly tricky. Most locations in the world will require a prescription from your doctor in order to purchase modafinil from an in-store pharmacy.

However, ordering modafinil online is much simpler as you do not need a prescription.

There are a lot of legal grey areas surrounding modafinil, which can make ordering the substance tricky, but does allows vendors to sell it to you.

As there are some countries that do not have any kind of restriction or regulation on modafinil and other prescription drugs, online pharmacies and vendors will typically be located in these countries. This means they can safely sell prescription drugs to the general public without the necessary documents.

  • Discounted Modafinil

Online vendors are a great place to purchase modafinil as they can typically offer more brands and therefore competitive rates. A lot of online pharmacies will offer discounts on their products.

When shopping for modafinil, a lot of generic and therefore cheaper brands work just as well as the named versions. This means that it doesn’t have to cost a lot for you to experience the alertness and motivation that modafinil and armodafinil can offer.

How Much Modafinil or Armodafinil Do I Need?

The dosage of modafinil or armodafinil that you need will differ depending on why you are taking the substance in the first place.

There are a range of popular reasons that people will seek out a modafinil treatment and the recommended dosage for each is different.

Modafinil For Sleep Conditions And ADHD

The average dosage of modafinil for sleep conditions, such as narcolepsy, or to aid the symptoms of ADHD is 200mg. This is likely going to be what is on your prescription should you have visited the doctors for any of these illnesses.

If you want to take armodafinil instead, which is stronger than modafinil, then it is likely that the dosage will be around 150mg.

Depending on how severe your sleep condition or ADHD is, your dosage of modafinil can be as high as 500mg or 250mg for armodafinil.

If you suffer from ADHD, then your prescription will require you to take either modafinil or armodafinil on a daily basis. On this kind of treatment, you need to take one to two days off every week to prevent building a tolerance or any long-term side effects.

The treatment for narcolepsy is fairly similar except there isn’t a break in taking modafinil or armodafinil. If you do take a break, then chances are your symptoms will flare up again.

When you start taking modafinil for narcolepsy or other sleep conditions you need to determine how severe your condition is and therefore how strong your treatment should be.

Modafinil or Armodafinil For Cognitive Enhancement

This is perhaps the most popular off-label use of modafinil or armodafinil. Both substances can make you feel more alert, keep you awake and increase your productivity which is why many students and business owners are seeking treatment.

The dosage range of both modafinil or armodafinil can range from 50mg to 400mg, depending on what your motivations are.

When taking modafinil for off-label benefits, you need to also consider your size and weight, how reactive you are to the treatment, and how often you are going to be taking it.

There are a couple of ways that you can take modafinil or armodafinil for cognitive enhancement:

Small Dose (50mg)

Some people prefer to take modafinil in small doses for cognitive benefits. Although taking a small dose does weaken the initial effects of modafinil, it is safer for you in the long run.

Any dose of modafinil that is 50mg or less is considered to be a microdose, which means that it is below the therapeutic threshold.

Microdosing modafinil and armodafinil do offer less noticeable results initially, but it is much safer than any other dose. This means that this kind of treatment is easier to maintain in the long run, as you are less at risk of adverse side effects.

Many people use microdosing of modafinil as a replacement for caffeine during their working days, as both offer alertness and keep you awake for longer. Small doses of modafinil offer a gentle, low-grade feeling of wakefulness around 30 minutes after consumption without any of the jitters or anxiety that excess caffeine may cause.

However, taking small doses of modafinil can be tricky as the pills do not come in 50mg.

In order to get the dose of 50mg, 100mg tablets need to be broken in half or 200mg need to be cut into quarters. It is much easier to go down the halving route with 100mg, as most manufacturers actually press a line in the middle of the tablet so it can be equally divided.

Modafinil can also be given in powder form, which is typically measured in 50mg quarters. This powder can be put into your morning smoothie for a quicker release of the benefits.

Armodafinil can also be taken in 50mg, but this is likely going to be stronger than modafinil. Armodafinil is generally more intense than modafinil meaning a small dosage can still have the same effects as a high treatment of modafinil.

It may be a good idea to take a small dosage of modafinil if:

–        You’re a beginner to modafinil and want to test it out
–        You’re sensitive to modafinil and other stimulants
–        You plan on using modafinil for the long term (i.e., years)
–        You want to reduce the risk of side effects, such as anxiety

Having a small dosage of modafinil may be a good idea for most people who are using the drug to boost their cognitive performance, as it is safer in the long run.

Average Dosages (200mg)

This is the most popular dose of modafinil for cognitive enhancement. Due to this popularity, this is the dose that you are most likely to find online.

The usual dose of both Waklert and modafinil is 200mg, as this is the dosage that has the most research behind it. The equivalent dose of armodafinil is around 150mg as this is stronger than modafinil and less is needed for the same effects.

Taking 200mg of modafinil is beneficial to so many different people, due to the fact:

–        It is the easiest dose to take, as it is just one full tablet
–        There is a great deal of research behind this dose which means it is guaranteed to be effective and safe
–        Most common dosage to buy online or in pharmacies
–        Provides the well-known effects of cognitive enhancement

If you are used to modafinil or even if you want to get into a regular routine with the substance, taking an average dosage may be best for you.

However, if you notice any different or adverse effects when taking modafinil, you should stop your treatment and speak to a doctor.

Maximum Dosage (400mg)

If you want to take a large amount of modafinil, then you should not exceed 400mg. This is the safest high dosage of modafinil that will not cause adverse effects while still providing all of the cognitive benefits.

A high dose of modafinil is suitable for larger and heavier people or those who have developed a tolerance to the substance after repeated use.

This dosage is not recommended to those who have just started taking modafinil as this is likely to lead to adverse side effects. If you want to try a high dose, then you need to develop some form of tolerance beforehand, through using 50mg or 100mg of modafinil.

This ensures that you are not allergic or sensitive to the substance, which can be quite dangerous.

The equivalent dosage of armodafinil is 250mg which is the highest available version of this substance. Some armodafinil tablets do come in 150mg which means you can take two for a dose of 300mg.

However, you need to be aware that armodafinil is stronger than modafinil meaning the effects will be more intense. This is not suitable for beginners to stimulants of this kind.

Taking a high dosage of modafinil is suitable for you if:

–        You have a large build and are heavy meaning you can tolerate more
–        You have a fast drug metabolism
–        You want to take modafinil for short-term
–        You have been taking modafinil for a long time and have a high tolerance
–        You want the best results of the stimulant

Taking a high dose of either modafinil or armodafinil can put you more at risk of adverse side effects.

Side Effects Of Modafinil

When taking high doses of modafinil, you need to be wary of:

–        Insomnia
–        Anxiety
–        Digestive issues
–        Headaches
–        Low appetite
–        Dry mouth and dehydration

If these side effects persist, you should consult your doctor.
