What is your daily nootropic stack looking like?

Curious what cognitive-focused stacks people are researching right now. The combination of Semax + Selank seems to be popular in the literature for complementary mechanisms — one primarily BDNF-modulating and the other anxiolytic via GABA.

Anyone looking at adding Dihexa to a cognitive research stack? The potency data is interesting but the research base is thin compared to the Russian peptides.
