Cognitive, mood & sleep
Largely Russian-origin nootropic chemistry, plus sleep and anxiolytic peptides. The thinnest registry record of any category on the site: almost nothing here has a registered human trial in English-language registries, which is a fact about the public record rather than proof of absence.

Reading on these compounds
Categories are editorial groupings by mechanism — they are not medical classifications, and membership is not a claim that a compound does what the group name suggests. Study counts include only trials whose registered intervention names the compound. Collected 2026-08-02 from ClinicalTrials.gov and Drugs@FDA. How this is put together.
