An improved system and method for a syringe capable of reducing re-usage and limiting wasted contents. The syringe has a plunger with a plunger plug that extends beyond the barrel of the syringe when the contents are fully dispensed and prevents the plunger from being drawn backward. The plunger may also consist of a two-piece design that separates upon exceeding a predetermined force when attempting to draw the plunger backward after use.
