Armodafinil vs. Modafinil: Is There a Difference?


In the media, modafinil is an incredibly popular smart drug. Between figures like Tim Ferriss and Dave Asprey, the drug has grown in popularity within Silicon Valley and across high performance professions.

When comparing armodafinil vs. modafinil there is a difference.

Armodafinil is more potent than modafinil because it is pure R-modafinil, the most psychoactive compound in modafinil. This is why armodafinil drugs (such as nuvigil, artvigil, waklert) are made in lower doses than modafinil.

Despite the similarities, armodafinil vs. modafinil isn’t a direct comparison because there are slightly different effects. Modafinil is more well-researched than armodafinil.

Armodafinil vs. Modafinil: Benefits and Differences

Most of the scientific evidence is focused on modafinil. This drug is a synthetic product made to combat fatigue in sleep deprived individuals. One 2011 study of armodafinil showed that 48 Navy air traffic controllers had fewer lapses of attention compared to the control who didn’t take the drug [1].

Modafinil studies are similar in focus and within the military. A study of personnel who were kept awake for 64 hours showed that modafinil was as effective as amphetamine for maintaining cognitive abilities and mood [2].

In order to understand the comparison of armodafinil vs. modafinil, it is also important to look for the different factors online in reviews.

Anecdotal reports create an interesting (but worthwhile) picture. While many anecdotes do not create data in a scientific sense, it is nonetheless interesting to see what the prevailing experience is like. This is one of the reasons we recommend something like Reddit or Longecity in order to get reviews from various people within the community.

Which Should I Buy Between Armodafinil vs. Modafinil?

One of the best (current) vendors is Afinil Express, which you can find here. Keep in mind that vendors for armodafinil and modafinil change very frequently.

Editors' Thoughts on Armodafinil vs. Modafinil

Even though I never expected this to be the case, armodafinil and modafinil affected me differently. Both gave me a strong boost in mental energy and helped me last for long stretches at a time, but modafinil seemed to come with fewer side effects than armodafinil.

Unfortunately, I only have a single point of reference for armodafinil, but the side effects after 5 – 6 hours were an intense pain in my chest that made it challenging to breathe. While I went for walks and tried many things to get rid of the chest pain, it did not go away until the next day.

One experience should not condemn the drug altogether. To be fair, I took the armodafinil after not taking either of the drugs for many months (so it could have just been an issue of how intense ANY of them were). However, it is interesting to note that the more intense / higher concentration of the drug caused such an effect.
