What Is Flmodafinil?

Flmodafinil — also called bisfluoromodafinil, lauflumide or CRL-40,940 — is structurally similar to smart drug Modafinil 200 mg, a prescription to promote wakefulness-enhancing agent that’s also commonly used as a nootropic.

It’s identical in structure, with the addition of two fluoride atoms. According to its creator, this slight change increases the strength of the drug by up to four times. Flmodafinil may also have a longer half-life, meaning that its effects can last longer .

Flmodafinil was patented in 2013 yet is not currently a prescription drug, but is undergoing clinical trials for use for narcolepsy and other sleep disorders.

Because of this, Flmodafinil can be purchased online for research purposes only. fairly easily — but this could change at any time if it were to be approved for prescription use or if the regulations governing compounds that are structurally-similar to prescription drugs were to change.

Benefits of Flmodafinil

Extrapolating what we know about Modafinil, here are some of the potential benefits of Flmodafinil:

  • Neuroprotective agent. Like coffee, CRL-40,940 has the effect of caffeine. It is a drug that will keep you alert and active. One positive point is that Its effects last for a longer period compared to modafinil.
  • Dopamine reuptake inhibitor. When you are feeling a little bit off that means there is not enough dopamine available. The product works to produce feelings of excitement, reward, and confidence.
  • Antidepressant. CRL-40,940 spreads a feeling of excitement making you feel great and not want to sleep or be unproductive.
  • Anti-aggressive. It works to improve aggressive conditions. It works as an inhibitor that calms you at times when you feel uneasy or agitated.It is a nootropic that promises its users wakefulness, focus, and enhanced mental alertness. There are also additional benefits that you can get from it. Its use can also be accounted for the following effects:
  • Enhanced cognition. It works as a central nervous system stimulant keeping you alert, awake, and feeling good. It also improved concentration. In short, it tells your brain to avoid daytime sleepiness and boosts your motivation when you need it the most.
  • Decreased risk of depression. The chemical carries feelings of excitement and pleasure to all the neurons. When you feel down, the antidepressant effect supplement can help you feel better and positive. When used, it targets the dopamine receptors to increase dopamine so you feel positive and you become a quick thinker.
  • Increased productivity. Since it can increase the dopamine levels, you feel more energetic to finish all the day’s tasks. You might even have that extra energy to double your productivity while you still feel motivated.
  • Increased, long-lasting energy: If it works similarly to Modafinil, Flmodafinil may improve wakefulness in subjects with sleep disorders, increase energy for subjects with fatigue and neutralize some of the harmful effects of sleep deprivation.
  • Better memory and learning skills: It may also help to improve recall, attentiveness and learning skills in both healthy subjects and those with depression.
  • Improved mood and more motivation: Animal studies show improvements in motivation and drive with Modafinil use, while it can also serve as a mood booster for healthy people.
  • Intense focus and concentration: Whether a subject is sleep deprived or getting enough sleep, Modafinil can help improve focus — and Flmodafinil likely works similarly.

We reiterate that much of what we “know” about Flmodafinil is based on what we’ve learned about Modafinil.

Flmodafinil has only been around since 2013, and has been undergoing clinical trials since 2015. Hopefully, we will soon know much more about this compound.

Flmodafinil Side Effects and Safety

Because Flmodafinil is relatively new and still undergoing clinical safety and efficacy trials, there’s really not much information for us to report on its known and proven side effects.

However, seeing as Flmodafinil is the bisfluoroanalog to Modafinil, the two are very similar structurally, and therefore may have similar side effects.

Additionally, the creator of Flmodafinil reports in its patent that this newer compound has fewer and milder side effects than Modafinil.

This is backed up by anecdotal reports from research subjects who’ve used both Modafinil and Flmodafinil, too.

Here are some of the most common side effects that research subjects may experience from Flmodafinil.


Like Modafinil, Flmodafinil is a wakefulness-promoting agent that’s designed for use in subjects with sleep disorders. In fact, when a research subject is administered either compound late in the day, they may find themselves tossing and turning, unable to fall asleep later that night.

That’s why most eugeroic researchers advise that Flmodafinil be administered first thing in the morning.


One fairly commonly reported side effect of Modafinil is a headache, so we can surmise that Flmodafinil may cause headaches due to lack of water.

However, we’ve seen mixed reports of research subjects experiencing headache after taking Flmodafinil most commonly attributed to . In fact, on Reddit, we’ve even seen one Modafinil user who had been experiencing headaches, which had ceased when he quit Flmodafinil.


Anxiety is sometimes a side effect of these types of brain-enhancing compounds, but fortunately many Flmodafinil research subjects report that its effects are very “clean” — no anxiety and no crush, just energy, focus, and drive.

Gastrointestinal Issues

We know that several gastrointestinal side effects are attributed to Modafinil use — like nausea, diarrhea, constipation, gas, heartburn, or decreased appetite.

In fact, decreased appetite is a commonly-reported side effect for many nootropics and stimulants.

To avoid the other unpleasant gastrointestinal symptoms, we find that research subjects often start with a very low dose and slowly work their way up.

Drug Interactions

Modafinil may have interactions with blood thinners, antidepressants, certain antifungal medications, anti-seizure medications and anti-anxiety medications.

Flmodafinil may have similar drug interactions, although at this has not been proven.

Either way, subjects with any medical conditions or who are taking any prescription drugs are well-advised to think twice before researching Flmodafinil.

Other Safety Concerns

As with any other nootrpopic, prescription or over-the-counter drug or dietary supplement, research subjects should be well-informed on all safety concerns potentially applicable to them.

Subjects may want to avoid drinking caffeine while taking Flmodafinil because Flmodafinil is itself a stimulant.

Additionally, subjects should avoid using alcohol or mind-altering substances when using Flmodafinil.

Likewise, Flmodafinil may possess the same habit-forming qualities as Modafinil. For this reason, research subjects are advised against taking it more than 4-5 times per week as a nootropic, and to take regular breaks from all nootropic use.

Overall, however, Flmodafinil appears to be safe for otherwise healthy subjects.

Flmodafinil Dosage Side Effects

The creator of Flmodafinil has stated that it’s up to four times as strong as Modafinil. However, in practice, most research subjects report that it’s about twice or maybe about 1.5 times the strength of Modafinil.

In light of that, subjects should be cautious with dosing. Our own dosage guideline is that the standard Flmodafinil dose should be anywhere from one-quarter to one-half of a standard Modafinil dose.

12.5mg-25mg daily

We find that this low dose is popular among absolute beginner subjects. From what we know, healthy subjects are unlikely to experience any negative side effects from such a low dose.

Additionally, if a subject finds this low dose to be effective, they may be able to take it more than 2-3 times per week when needed.

50-100mg daily

This intermediate dose of Flmodafinil is based on the standard, 200mg dose of Modafinil. This amount seems to be right for most subjects, especially those who have used nootropics like Modafinil before.

Subjects may or may not experience some of the side effects listed above at this dosage. Our practice is to administer this dose early in the morning.

We do not administer Flmodafinil more than 6 days per week at this dosage.

150mg daily or more

This dose is approximately equivalent to 300mg or more of Modafinil per day. Some nootropics users do take 300mg of Modafinil to pull an all-nighter, so a very likely side effect of this high dose is insomnia. And of course, the larger the dose, the bigger the more likely that some other side effects could be experienced as well.


Based on our observations microdoses every 4-6 hours Flmodafinil provides sustained and consistent energy and without adverse side effects.

Depending on one’s level of experience and response to nootropics, we find that researchers can successfully dose anywhere from 25mg-125mg of Flmodafinil, 3 times daily, up to 4 days per week.

As always, we advise working up to an optimal dose.

Flmodafinil vs. Modafinil

By now you’re well aware that Flmodafinil and Modafinil have many similarities. However, here are some of the key aspects on which they differ:

  • Structure: Flmodafinil is identical to Modafinil, with the addition of two fluoride units.
  • Effects: Although their effects are similar, Flmodafinil is thought to be anywhere from 1.5-4 times stronger than Modafinil and to have a longer half-life (which means that it stays in one’s system for a longer duration).
  • Safety: Flmodafinil may have fewer side effects than Modafinil, but we are still awaiting results from clinical trials.
  • Prescription status: Modafinil is a prescription drug. Flmodafinil is not currently a prescription drug, but it is being studied for potential FDA approval, so this could change.
  • Body of research: We know much more about the safety and effectiveness of Modafinil than we do of Flmodafinil.
  • Cost: Surprisingly, Flmodafinil may be more expensive than Modafinil in most cases. It’s stronger, as well as a newer formulation.

Where to Buy Flmodafinil Online in 2021 Guide

The best place to buy Flmodafinil online is a vendor called 99 SARMS. This website currently offers Flmodafinil in two different forms: capsule and powder form.

However, you’ll need to have an payment method to purchase Flmodafinil Capsules, which will require a little extra work on your part.

We like 99 SARMS because they have very high standards regarding ingredient sourcing and testing.

In fact, every product they manufacture is analyzed by a third-party, independent testing company for purity, identification, structure, heavy metals, and contaminants. Then, 99 SARMs verifies the results of the third-party testing with their own in-house testing. All of the reports and batch tests are not available on the website.

Side Effects of Flmodafinil | The Last Word

Flmodafinil shows tons of promise as a new nootropic on the scene, with the potential to be much stronger and to have longer-lasting effects than even Modafinil — possibly with fewer side effects!

For healthy subjects, Flmodafinil appears to be pretty safe. It’s vital, however, to be well-informed of all potential side effects and start researching a conservative dose.

    If i take a little bit, I get a smooth increase in energy levels. No loss of motivation or attention span. Great for at work.
    When I take your average amount or a little more, its like a super modafinil but, much smoother. I dont feel cranked however, I definitely am.
    I'll do the larger amount for staying up light working on my buisness or, reading studies.

    These are really just like dopa, and make it hard to sleep. They do however, offer no clarity or focus. Actually, it's the opposite, since dopa is often an emotional response. I

    I don't have another source to compare this product to, but I have always been pleased with the nootropic products 99Sarm's offer. In particular, my focus and concentration are heightened with this product and I feel more engaged in the work I do

    This is the real thing if I compare with what I got previously from a reliable and more expensive source. It gives a smoother stimulation than modafinil, less disconnected from others. It also lasts longer. I take it before I wake up so as not to disturb my sleep at night. If I forgot to take it then I skip it to prevent staying awake too long. I take the week-ends off. I still feel the effects the next day. There's part of the stimulation that is not directly related to the molecule but to one of its effect IMO. No need to increase the dosage with time. I prefer the powder and order 10g at a time. To pay for the product I skip buying coffee during the day. My preferred coffee was the blonde from Starbucks, grande of course.

    Idk what happened to the quality of this stuff... the white & green capsules were amazing, top notch, the best... my last order the colour of the capsules changed, one bottle was all green capsules & 2 bottles were different shades of blue. I can almost guarantee with absolute certainty neither contain flmodafinil.. i can sleep like a baby after 4 capsules & (gross i know) but the urine smell change didn't occur. Idk what i got this time but i'm in the process of sending it to a private lab. I LOVED this product. Not sure what happened but I'm really disappointed.
