A medicated module (4) for an injection system to co-deliver at least two medicaments is disclosed where a primary delivery device containing a primary medicament accepts a medicated module (4) containing a single dose of a secondary medicament and where both medicaments are delivered through a hollow needle (3). The medicated module (4) is user selectable so that it will deliver a priming dose of a primary medicament or both the primary and secondary medicaments. The module (4) also contains a needle guard (42) that locks after dose delivery. The needle guard (42) prevents accidental needle sticks before and after an injection. A locking collar (66) rotates during use as an inner protrusion (12) follows three paths (14, 15, 16) of a track (13) located on the outer surface of a body housing (10). When the inner facing protrusion (12) is in the third path (16), it encounters a hard stop and a rotational bias that locks the guard (42) from further retraction and thus covers the sharp distal end of the needle (3).
