A method and system for proving a drug delivery device having a variable maximum dose. The drug delivery device comprising a first tubular member (260) and a second tubular member (300) rotatably coupled to the first tubular member (260). A maximum stop component (286a,b) is operatively coupled to the first tubular member (260) and the second tubular member (300) such that the maximum stop component (286a,b) is movable from a first position to a second position. The first position defines a first maximum dose that may be set by a user of said drug delivery device and the second position defines a second maximum dose that may be set by the user of said drug delivery device.
