Abstract: A syringe, a kit, methods of making and methods of using the same are provided. The syringe includes a syringe body defining an interior volume. The syringe body defines a first opening at a distal end for dispensing and a second opening at a proximal end. The syringe further includes a stopper disposed inside the barrel, optionally a stopper insert coupled with the stopper, and a plunger rod disposed outside the syringe body. The plunger rod has a first end, a second end, and a middle section. The middle section is disposed along the barrel wall. The first end of the plunger rod is configured to be coupled with the stopper or the stopper insert, and the second end is reversibly attached to the distal end or the proximal end of the syringe body. The plunger rod can be detached and assembled with the stopper or the stopper insert so as to drive the stopper for injection.
