investigational
Being tested now
Investigational describes something being formally studied or tested but not yet approved for general use.
The term appears most often in medical and pharmaceutical contexts: an investigational drug, an investigational treatment.
It signals that something shows promise but remains under evaluation—available only in clinical trials or research settings, not yet cleared by regulatory authorities.
