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.
