I'm not educated enough in this to specify a single drug / nootropic. It's just always seemed like the professional leagues leave a large gap in coverage of their tests if they are (a) testing for "performance enhancing drugs", and (b) leave out drugs that improve mental performance. If they do test for this type of drug I've just never been made aware of it.
