What is Adrafinil?

Adrafinil is a mild stimulant drug that was developed in France as a wakefulness-promoting agent (eugeroic). It was marketed under the brand name Olmifon until it was discontinued in 2011.

This drug was intended for use by patients who suffer from excessive daytime sleepiness, fatigue and inattention due to sleeping disorders or other mental disorders. But it didn't stop there; many healthy people also started using adrafinil off-label to help them stay awake and focused. Today, it is one of the most widely used over-the-counter nootropics.

Although its brand version (Olmifon) is no longer sold, there are many companies that make and sell generic adrafinil as bulk powder or in capsule form.

Characteristics of Real Adrafinil

Adrafinil powder has a light pinkish or off-white color. It has a slightly bitter taste and a mild sulfur smell. Color and smell may slightly differ from one manufacturer to another.

The powder is fully soluble in ethanol and methanol, and partially soluble in water.

Effects and Benefits

Adrafinil mildly stimulates the central nervous system. It is the closest thing to prescription stimulants you can buy over the counter.

These are the general results you can experience when taking adrafinil:

  • Increased focus: not in any supernatural way, but it helps you concentrate on what you are doing with better mental clarity.
  • Feeling energized and alert: fends off tiredness and makes you want to stay awake and active.
  • Better mood: this can range from feeling a little bit jolly to a short state of euphoria.
  • Feeling positive: it gives you a kick of motivation and willingness to work.
  • Better sleep: makes it easier to fall asleep at night and wake up in the morning feeling like you really have had a good night's sleep.


  1. I do not promise that you will experience these results as they vary for each individual. Some users have better results with this drug than others, and there is no way to tell how well it will work for you until you try it yourself. It does work though!
  2. You will have a greater benefit if you take it when you are tired or sleepy. If you are already in a good mental state then you probably won't notice any change after taking the dose, and you shouldn't need to anyway.

Dosage and Usage

The standard dose for adrafinil is 300mg. But depending on your weight and other factors, you may need a lower or higher dosage to notice effects.

If you are a beginner, start by taking a 300mg dose in the morning or midday. If you don't feel any significant effect after a couple of days, you can double the dose to 600mg in the morning, or 300mg in the morning and another 300mg in the afternoon.

You can take it every day (no more than 900mg), every other day, or as required; whichever suits your needs best. Avoid taking it in the evening unless you want to stay awake during the night. Take it with a glass of water, or if you are using the powder you can mix it with your favorite drink. Works better on an empty stomach.

Adrafinil starts working in about one hour after ingestion (more or less), and it remains active in your system for several hours.

Tolerance and Cycling

Your body can build up tolerance to adrafinil if used very often, which leads to the dose becoming ineffective or having a very negligible effect. To prevent this from happening it is recommended to cycle adrafinil.

Cycling means taking a break between doses, or using the drug on and off, so that it will maintain its effects on you without having to constantly increase the dosage. There are no clinical guidelines for cycling adrafinil, but based on individual experiences it is recommended to take at least a day off between doses. So you should take it day on day off, or 3 times a week max.

Sublingual Administration

Adrafinil should be administered orally (swallowed with liquid), and this is the standard way to take it that has been clinically tested. Some users have taken it sublingually (under the tongue) and claimed it works faster that way.

Either way, the drug will enter your blood stream after ingestion, and once it reaches the liver it will be metabolized into modafinil.

It seems to be safe to take the dose sublingually, but if you are a new user it is better to take it orally first, and if it doesn't yield much of an effect you can try a sublingual dose (50-100mg).

Does Adrafinil Really Work?

According to the published scientific literature, adrafinil does indeed have a positive effect on vigilance, concentration, attention, clarity, memory, and mood. But does it work for everyone? The answer is no. Some users do not respond to adrafinil, modafinil, and the whole -afinil family of drugs. Others may experience varying degree of efficacy.

In general, the following groups of people are more likely to notice improvement when taking this drug:

  • People with low mental energy, depression and/or lacking motivation.
  • People having difficulty staying alert and focused.
  • People suffering from daytime sleepiness and fatigue.
  • Older people (45+).

If you are a healthy individual then you probably won't feel much change after taking adrafinil.

Safety and Side Effects

Adrafinil is generally safe and does not cause any significant side effects when taken within the normal dosage. At high doses some side effects may be noticed including anxiety, headache, dizziness, insomnia, and frequent pooping.

Avoid taking adrafinil with other simulants like Adderall, Ritalin, or even caffeine. The combination may worsen adverse effects, and may even be risky.

There have been concerns about liver toxicity. Adrafinil is metabolized in the liver where it gets converted to its active drug form; Modafinil. This process causes liver enzymes to rise above normal levels. This also happens with many other medications such as aspirin, ibuprofen (Advil), atorvastatin (Lipitor), and others.

No clinical studies available on the long-term side effects of adrafinil, but just to be safe, if you are going to use it every day you should not do so for more than 4-5 months. Also avoid consuming it with alcohol or other medications that raise liver enzymes.

Adrafinil vs. Caffeine

You can use adrafinil as an alternative to caffeine. It gives you a similar mental stimulating benefit without the jitters. But since effectiveness varies - not just from user to user, but also from dose to dose - adrafinil may not be as reliable as caffeine.

Avoid taking both adrafinil and caffeine together, otherwise the combination can make you very nervous and anxious.

Adrafinil and Modafinil

Adrafinil is a precursor drug (prodrug) to modafinil. After it is absorbed by the body it gets metabolized in the liver into modafinil (the active drug form). So, in essence both adrafinil and modafinil have the same effect in the body.

Modafinil, however, is a prescription-only drug that is sold under different brand names including Alertec, Modavigil, and Provigil. Modafinil as a stand-alone drug is more potent than adrafinil, and has more palpable side effects.

For off-label use as a cognitive enhancer, adrafinil is the better choice since you can buy it without a prescription and it doesn't have an acute stimulant effect.

Adrafinil is an unscheduled drug in the USA, Canada, UK, Europe and most other countries. That means it is legal to buy it over the counter for personal use.

In Australia and France, however, it is classified as prescription-only. Some online stores will still ship to these two countries and the shipment normally goes through if it is a small amount and intended for personal use.

Adrafinil and modafinil are both banned stimulants by the World Anti-Doping Agency (athletes are not allowed to take them in competition).

Most users order adrafinil online, although you may also be able to source it locally. There are many online nootropics suppliers that sell adrafinil with varying quality and prices. You can check out this list of suppliers to compare some of the best online stores where you can get adrafinil capsules or powder at reasonably low prices.
