It's my understanding that most of the nootropic drugs are temporary stimulating agents.


Some outcomes more anecdotally profound than others.



The really interesting stuff is the nerve growth factor in the nootropic, cerebrolysin.  The Russians have been using it forever and there are some interesting fast time elapsed videos of axon/dendrite (??) formation with and without cerebrolysin.  But these nerve cell samples were outside of the body - so I believe it's fairly difficult to keep nerve cells alive in culture.

So, the videos might not be legitimate.
