Where can I find non bias information on nootropics?

So I'm interested in a social anxiety/focus nootropic to take periodically. I'm very hesitant when it comes to taking any sort of drug. I've been looking at aniracteam and noopet particularly. Can anyone point me to a non bias source that gives me some good backed up facts on nootropics. When I search these nootropics, all that comes up is nootropics websites that are obviously trying to pitch a product without any solid evidence backing them. I've also found websites on the opposite side of the spectrum saying aniractam is dangerous with around 70 negative amazon reviews to back it up. I really don't know what to believe and how effective these products actually are.
