A dynamic identification system for a multi-dose injection device includes a dose dial sleeve (40) containing indicia (41； 42) of the medicament contained within the device becomes visible or available to the olfactory or gustation senses only during dose setting as the dial sleeve (40) is translated proximally out of the outer housing of the device. A user can readily identify the medicament contained within the device (1) as the dose is being set. A static identifier (50) located on the device that matches the dynamic identifier on the dial sleeve (40) can also be used as a medicament identifier.
