Modalert vs Modvigil vs Waklert vs Artvigil

The various versions of Modafinil and Armodafinil. From left to right (Modalert, Modvigil, Waklert, Artvigil.)

I’ve been on quite the Modafinil binge the past month leading to insane levels of productivity in my work and in my nootropics research. I like to take nootropics and simultaneously research them while I am experiencing their effects.

When you begin to study Modafinil you begin to realize there are many different variants of the compound sold through various pharmacies. It becomes confusing to figure out which version you should buy or start with.

I did the research so you didn’t have to. Below I break down each individual variant of Modafinil.

Perhaps the most common form of Modafinil available through popular vendors like Buy Moda. Modalert is simply a branded form of Modafinil sold by Sun Pharma Pharmacies. Sun Pharma is a massive multinational Pharmacy located in India. Sun Pharma synthesizes many pharmaceutical formulas and is well known and trusted in the industry. Modalert is the Sun Pharma version of Modafinil.


Modvigil is Modafinil synthesized by HAB Pharmaceuticals. HAB Pharma is a much smaller company than Sun Pharma. Despite this, their version of Modafinil is held in high regard and is similar in quality to Modalert. Modvigil is slightly less expensive than Modalert so many users choose this product over Modalert.


Waklert is Armodafinil synthesized by Sun Pharma. Armodafinil is considered a much more efficient version of Modafinil with longer lasting effects. Also, where 200mg of Modafinil is needed only 150mg of Armodafinil is required due to this efficiency.


Artvigil is Armodafinil produced by HAB Pharma. You are probably beginning to see a pattern here. There are 2 companies producing all the Modafinil in the market and they manufacture both Modafinil AND Armodafinil with the latter being a slightly updated and more efficient compound.

What version of Modafinil to choose?

I’ve been lucky to experiment with all the variants of Modafinil thanks to Duck Dose. They sent me a bunch of samples and I was happy to test out each and every one of them.

My experience so far is that Sun Pharma Modafinil feels more effective to me. Modalert and Waklert have been very effective in waking me up, delivering mental energy, and providing a long lasting boost in productivity and wakefulness. That’s not to say the Modvigil and Artvigil weren’t effective because they certainly were. They just didn’t seem to have the same kick as the Sun Pharma versions.

However, both Armodafinil versions blew the Modafinil versions out of the water. These versions come in 150mg tablets and last a very long time. I normally have no problem going to sleep at night if I take the Modalert or Modvigil. However, taking the Waklert or Artvigil even early in the day keeps me up for most of the night. My solution was to stick to the regular Modafinil or simply split the 150mg Armodafinil tablets in half.


Final thoughts

That should clear up any confusion you have about the different Modafinil and Armodafinil versions. I cover this topic in extreme depth in my book The Modafinil Manual. It’s the best guide to the compound you’ll ever come across and comes loaded with a 30 minute video shot by yours truly.

Just remember, there are 2 primary companies producing Modafinil and both of them have their own names. In the end, it’s all the same compound being branded with their own names depending on who’s making it. Like I said, I found the Sun Pharma versions (Modalert, Waklert) to be slightly more effective than the HAB Pharma versions (Modvigil, Artvigil.)

My advice is that if you want the best you go with either the Modalert or the Waklert. While the HAB Pharma versions are cheaper, they really aren’t THAT much cheaper to justify going with the much smaller and less reputable company. I do not discredit their quality and testing – I am simply a sucker for the best brands.

Either way you go, you can be sure you’re going to go on a wild ride of energy and productivity.
