A syringe for hypodermic injection wherein multiple pistons seal various number of chambers. One piston provides the basic operating force to dispel the contents from a chamber or successive chambers. Another piston or other pistons form one or more additional chambers. The plurality of pistons permit release of the chamber contents or successive chamber contents. A syringe holder is provided for holding, using and disposing of the syringe minimizing potential of accidental sticking by the needle of the syringe.
