You need to dose it at about one 10th of regular modifinil. Sweet spot for me is around 30-40 mg. Careful. It lasts for 12-16 hours. Better to under dose and grab coffee later than overdo it at first.
I always stack with a mild pre or fat burner, around 100 mg of caffeine then a Diet Coke or two for another 100 mg throughout the day. But I don’t bother with the complicated nootropic stacks all over Reddit. Without caffeine it’s hard to get the right balance. Moda is a tweaky/ twitchy awake feeling. Not bad like yohimbine shakes. No BP issues. No muscle pain. No nausea.
Also, use it sparingly. There’s no need for this kind of compound daily.
