- "Ha! Stimulants make a warrior out of even the weakest humans."
- ―Canderous Ordo
A stimulant, also referred to as a stim, was a chemical mixture targeted towards the adrenal system, in the form of a one-time use shot, that was injected into the bloodstream in order to provide a boost to the physical capabilities of the user. This enhancement was most commonly used by individuals that were preparing for or already in the midst of a battle. The Mandalorian Canderous Ordo was adept at preparing stims, which he freely offered to both Revan and the Jedi Exile during his travels with them.
The effect was described as "like ten hours of good, deep sleep, and four square meals" until they wore off.
