​Modafinil comes in many different forms, making it suitable for many different drug and supplement companies. Many of them do not allow Modafinil to be sold over-the-counter as we covered earlier. Many of them also only carry a small dose per day; for example, some of them are only 1-2mg per tablet. With that being said, with the increasing popularity of digitalization, you may see more options available. These include generic forms, along with their respective strengths.
