CRL 40941, Fladrafinil, the Extremely Potent Nootropic Modafinil Analogue

If you’ve stumbled upon this article from Google searching “CRL 40941,” since you’re searching the actual chemical name of a nootropic, research chemical Smart Drug, then I’m going to assume that you probably aren’t new to nootropics, and that instead you’re something of an experienced reader. Well, if you weren’t already sure, CRL-40941 is the chemical name for the Modafinil analogue called Fladrafinil, which on paper is said to be 3-6 times stronger than the prescription drug Provigil.

It’s also in my opinion significantly riskier, but more on that in a bit. Fladrafinil, because of it’s risk to buy, is also somewhat risky to sell (like you wouldn’t believe) so it may be hard to get your hands on. This blog post will go over every online shop where you can purchase CRL 40941, and will give you links to some valuable and potent alternatives. If you want to buy some of these super powerful Smart Drugs, you may want to get used to using Bitcoin, as it’s sort of the online currency of choice for high risk supplements.

What is CRL 40941?

CRL 40941 is the chemical name for the Smart Drug known as Fladrafinil, a potent and legal Analogue of Modafinil (or at least not scheduled) that allows the user increased focus, memory and cognition and that is so strong it should not be taken on a regular basis, but instead on as-needed schedule. Fladrafinil is often times compared to a host of other related drugs, both Analogues of Modafinil and Prescription alternatives to the drug Modafinil itself. These include:

Fladrafinil-The primary drug and primary topic of discussion of this article, Fladrafinil is also sometimes called CRL-40941. Fladrafinil is one of the most powerful analogues of Modafinil on the market, and is said to sometimes be up to 4 to 8 times stronger than Provigil on a dosage by dosage basis.

Flmodafinil- Another very similar analogue to that of Provigil and Fladrafinil, Flmodafinil is nearly identical in effects to Fladrafinil but is about one level stronger.

Adrafinil-Adrafinil is a very widely sold nootropic, and you can get it at a host of online stores, including Ebay, Amazon, Powder City, Nootropics City, Smart Drugs for College, Absorb your Health, Nootropic Nation and Peak Nootropics, There are literally dozens of stores that sell this nootropic, it is popular, it is potent, and while it is a bit expensive, it is very easy to find online. It’s effects are almost identical to that of Provigil and Modafinil, although it is a tad bit weaker, does not last as long, and is somewhat harsher on the liver.

Hydrafinil (9-Fluorenol)-Hydrafinil is a real beauty of mine, and is what I think is one of the most powerful nootropics currently on the market. It is actually stronger than Provigil, Modafinil and Armodafinil by a factor of 4 with regards to dosing and potency, and while it doesn’t last as long, does not require a prescription and is totally legal to buy and purchase. Hydrafinil is something of a suite spot for me, since while it is legal, it is in something of a high risk category to sell based on overall supplement regulations, and my old company Smart Drugs for College used to sell it.

The only websites I know of that sell this product are:

Ahh Modafinil, a drug that some in nootropics call the “Holy Grail” of brain supplements. Provigil is prescription only, and is actually quite difficult to get your hands on if you don’t know a source, however it’s reputation certainly lives up to the hype, and pound for pound, it might actually be the best nootropic that you can currently buy. Though not without its fair share of side effects, in comparison to other powerful nootropics, these are somewhat mild, and the benefits of this Smart Drug far outweight the downsides.


Brand name Modafinil.


An upgraded form of Modafinil, Armodafinil actually just recently came out within the past 5 years (or at least that’s when it became popular enough to talk about on Smart Drug forums) and has lived up to the hype as Modafinil’s big brother. Armodafinil lasts about 33% longer than Provigil, and is an overall stronger drug on a 150 milligram dosage versus Modafinil’s two hundred milligram one.

How to use CRL 40941

Now back to it, CRL 40941 is a high risk, Modafinil analogue and research chemical nootropic that can have some truly amazing brain benefits if it’s taken properly.

CRL-40941 Fladrafinil

CRL 40941 Dosage

Typical dosages of CRL 40941 range from 20 to 30 milligrams, taken one to two times daily. My advice if you decide to take this high risk nootropic drug is to absolutely use caution, as reviews of dosing restrictions on popular nootropics forums as well as research websites vary quite significantly from website to website. No one that I know of sells this product in capsules, however a few companies sell it, or used to sell it, in powder form, which demands extra caution for the reason that you’ll need a proper milligram scoop and milligram scale in order to dose the drug properly.

CRL-40941 Side Effects and a Video Review of the Drug

CRL 40941 is a very potent Smart Drug that absolutely demands caution with dosing due to its potency, lest a host of nasty side effects could possibly occur. The following is a video review about using nootropics properly, as well as one user’s experience with them. This guy is a multi-millionaire with a net worth of 8 figures, $20,000,000.00 and counting, and he is also a very avid and regular user of Smart Drugs! It goes to show that risk, when coupled with caution and an intelligent strategy, can have amazing effects on the brain, and your overall success in life.

Now back on the subject of side effects with Fladrafinil, if taken at appropriate, low dosages of around 20 to 30 milligrams at a time, side effects should be rare if they do occur at all. With this being said, one bad measurement, like if you go up to 50 or 60 milligrams at a time, can have some pretty nasty side effects, and can cause the drug to last far longer than it should, upwards of 16 to 18 hours, so I’ll stress again that if you decide to use this Smart Drug, extreme caution is advised. I’ll also say that drugs like Provigil and Adrafinil, are much better and much safer alternatives to Fladrafinil overall.

CRL 40941 vs other Modafinil Analogues

Other Modafinil analogues that Fladrafinil is very commonly compared to include:





Each of these has their own risks and rewards, and you can read more about these in aformentioned articles earlier in this blog post, as well as in the respective category entitled “Modafinil Analogues” on the right hand side of this blog post.

CRL40941 Research

Fladrafinil, or CRL40941, actually has very little research behind it. The following are the only .gov clinical trial research articles that I could find on the drug.

CRL 40941 vs Other Nootropics

Other great nootropic alternatives to this Smart Drug, as well as drugs that users often times stack together or with this compound (which is actually highly advised against) include:







CDP Choline

Alpha GPC Choline







D-Aspartic Acid


Liposomal Curcumin


Rhodiola Rosea Root Extract, 3% Salidroside

Milk Thistle





St. John’s Wort

American Ginseng

Garcina Cambogia

These are just a host of the multitude of nootropics and herbal supplements that users combine into stack compounds. Always do your own research, both on legality in your country (as some of these are banned in the United Kingdom, Italy and Germany, and I personally know of companies including my own that have had problems with customs seizing parcels that have been shipped there) and on side effects and proper usage guidelines of these supplements.

Why Fladrafinil, CRL 40941, is a great, yet Risky Nootropic

Any supplement that is raved about as being more effective as Modafinil is definitely going to turn heads as a way of getting users on board. With this supplement however, I’d recommend caution, or to even stay away from it. Nearly any of the listed alternatives are a better product, and overall this looks like a supplement to be safe from, rather than sorry for regular use.

Stores that Sell CRL 40941 or that Blog About the Drug Similarly to this Website

Final Thoughts on CRL 40941

Overall, CRL has it’s risks and it’s rewards, and I leave it up to you, a capable reader, to take the information given in this article and make an informed decision about your brain boosting supplement use. In my humble opinion, as a user of nootropics for over a decade and a salesman of them for going on 5 years now, I’d recommend to stear clear of this one, and to look into something like Adrafinil, Hydrafinil, Provigil, Piracetam or Aniracetam, as a safe and valuable alternative supplement.
