Selank is probably my favorite. As for the HD Vision, I read a paper last year about it, but fail to remember what is the mecanism of action. Noopept do that too as well as Fasoracetam. Edit: Glutamate

Because of the lack of Human Trials, Nootropics should be taken with precautions. I wouldn't feel comfortable to suggest more novel compounds, that being said, Piracetam and Noopept are great for starter
