         52 . A multi-site injection system comprising:
 a guide plate having a plurality of openings therethrough;   a needle plate having a plurality of needles projecting therefrom, each needle being aligned with a corresponding opening in said guide plate, said needle plate being movable from a first position with the needles positioned behind a top surface of said guide plate to a second position with the needles projecting from the top surface through the openings; and   a plunger base for moving said needle plate from the first to the second position.   
     
     
         53 . The system according to  claim 52  wherein said plunger bore includes a reservoir for medicament and needles include lumen therethrough in communication with said reservoir for delivery of the medicament into a stratum corneum of a user's skin. 
     
     
         54 . The system according to  claim 52  wherein the needles and opening are arranged in a symmetric radial pattern. 
     
     
         55 . The system according to  claim 52  wherein the needles and opening are arranged in an asymmetric radial pattern. 
     
     
         56 . A multi-site injection system comprising:
 a handle;   a syringe supported by said handle and including a plunger for dispensing a fluid medicament from said syringe;   a manifold attached to one end of said handle and in fluid communication with said syringe;   a plurality of needles, protruding from said manifold, for delivery of said fluid medicament from said manifold and into a stratum corneum of a user.   
     
     
         57 . The system according to  claim 56  wherein said manifold is disposed perpendicular to said handle. 
     
     
         58 . The system according to  claim 56  wherein said manifold comprises a plurality of concentric conduits interconnected with radial conduits. 
     
     
         59 . The system according to  claim 56  wherein the concentric conduits are radially spaced apart from one another. 
     
     
         60 . The system according to  claim 59  further comprising a transparent sheet interconnecting the concentric and radial conduits for enabling visual orientation of said manifold onto a patient's skin by manipulation of said handle. 
     
     
         61 . A multi-site injection system comprising:
 a shell including a top and a bottom;   a plurality of needles protruding from the shell bottom, each needle including a lumen extending through the shell bottom;   a membrane disposed between the shell top and shell bottom;   an inlet for introducing a fluid between the shell top and the shell bottom; and   a diverter for selectively directing fluid between the membrane and the shell bottom and between the membrane and the shell top.   
     
     
         62 . The system according to  claim 61  wherein said diverter includes a manually operated valve.
