Nootropic stack for a student studying engineering

[seftango]

Hello guys, I’m studying robotics and cybernetics and need advice on a nootropic stack for studying, memory retention, and staying awake for long periods; ideally, I’d like to include Semax, since I already have 110 mg of it. Thanks in advance.
