A protosyringe for containing a liquid component in a delivery system for a multiple component needle coupling of a syringe filled with the liquid component. The protosyringe is used in conjunction with a transfer mechanism containing a double end needle assembly to transfer liquid to a vial containing a further component of the pharmaceutical which is then drawn back into the protosyringe. The transfer mechanism or part of it is then removed and discarded, including the vial and at least that end of the needle assembly penetrating the vial, so as to leave the syringe filled with both components and either presenting a needle coupling comprised by part of the needle assembly retained on the protosyringe, or presenting the original needle coupling of the syringe.
