This is one of my favorite nootropic supplements.
It contains l tyrosine and phenylalanine, which increase dopamine levels.
For this reason, I would advise that you cycle this supplement – don’t take it every day.
You may also want to look at ways in which you can unregulated your dopamine receptors, just to ensure that you’re not getting big ups and downs – I.e. crashing when you’re not using a dopamine-increasinf nootropic.
For example, meditating, and staying off social media, as well as taking sulbutimate and cordyceps should help reset your dopamine levels on your off days.
I suspect much of the effect of the supplement is from DMAE. This is a choline supplement that increases energy and focus quite effectively.
Just be aware, it can also cause anxiety and muscle stiffness.
All in all though, a good nootropic.
