A storage stable needleless fluid injection device comprising a reaction chamber capable of retaining a predetermined quantity of a chemical reagent that generates pressure when the chemical reagent is at least one of reacted, ignited, exploded, and decomposed, an initiator for initiating reaction, ignition, explosion and/or decomposition of the chemical reagent, a fluid retention chamber capable of retaining a fluid, wherein the fluid retention chamber includes an aperture, and means for dispensing a fluid retained within the fluid retention chamber out of the aperture, and in turn, into a human or animal body, or other object. The device is capable of generating pressures in excess of 500 p.s.i. with the use of only very small amounts of the chemical reagent. Such high pressures enable needless injections to deep sub-dermal locations within a body or other desired environments.
