1. A syringe comprising: a handle having a first flange and a second flange forming a handgrip;a first arc forming a bottom surface of the first flange contoured to correspond to a radius of an arc formed by a user's fingers;a second arc forming a bottom surface of the second flange contoured to correspond to a radius of an arc formed by the user's fingers and shaped flatter than the first arc;a syringe barrel having an outer barrel and an inner barrel, the inner barrel having dosage marks and a needle mounted at a distal end, the outer barrel shaped to receive the inner barrel and having an elliptical cross section to magnify the dosage marks located on the inner barrel; anda tip cap slidably engageable with a distal end of the syringe barrel for shielding the needle comprising, an outer cap;an inner cap; anda connector shaped to fit within and engage the outer cap and engage the inner cap and having a plurality of first legs spaced symmetrically away from one another, each first leg having a plurality of internally facing barbs pointing toward a distal region of the connector and adapted to engage a proximal region of the inner cap, wherein the plurality of internally facing barbs are disposed at an angle with respect to the plurality of first legs, the connector having a plurality of second legs spaced symmetrically away from one another, each second leg having a plurality of externally facing barbs located in the distal region of the connector and adapted to engage a distal region of the outer cap;wherein the outer barrel includes a first recess and a second recess shaped to receive the tip cap. 2. The syringe of claim 1, wherein the outer cap includes a first protrusion and a second protrusion formed on an inner surface of a shoulder at the outer cap, wherein the first and second protrusions interfit with the first recess and the second recess of the outer barrel, respectively. 3. The syringe of claim 1, wherein the outer cap includes a gripping ring. 4. The syringe of claim 3, wherein the gripping ring is shaped to receive the user's finger to engage the ring. 5. The syringe of claim 3, wherein the gripping ring is shaped to receive a hook. 6. The syringe of claim 1, wherein the plurality of first legs are biased initially at about 80 degrees with respect to the horizontal. 7. The syringe of claim 1, wherein the outer barrel includes a distal aperture to allow the inner barrel to extend through the aperture. 8. The syringe of claim 1, wherein the second flange is 1.5 times as long as the first flange. 9. The syringe of claim 1, wherein the outer barrel has a major diameter and a minor diameter, wherein the ratio between the major diameter and the minor diameter is 1.5:1. 10. The syringe of claim 1, wherein the inner barrel is positioned within the outer barrel such that the dosage marks are oriented at one end of the major diameter for magnifying the dosage marks. 11. A syringe comprising: a handle having a first flange and a second flange forming a handgrip;a first arc forming a bottom surface of the first flange contoured to correspond to a radius of an arc formed by a user's fingers;a second arc forming a bottom surface of the second flange contoured to correspond to a radius of an arc formed by the user's fingers and shaped flatter than the first arc;a syringe barrel having an outer barrel and an inner barrel, the inner barrel having dosage marks and a needle mounted at a distal end, the outer barrel shaped to receive the inner barrel and having an elliptical cross section to magnify the dosage marks located on the inner barrel, wherein the outer barrel includes proximal and distal ends and a recess formed at the distal end, and wherein the outer barrel has a major diameter and a minor diameter, wherein a first recess is formed at a first end of the major diameter and a second recess is formed at an opposite end of the major diameter; anda tip cap for shielding the needle including a shoulder having an inner surface and an outer surface, a mating protrusion formed on the inner surface and shaped to matingly engage with the recess formed on the outer barrel. 12. The syringe of claim 11, wherein the tip cap includes an inner cap that is received within the outer cap. 13. The syringe of claim 11, wherein the inner barrel is disposed within the tip cap when the tip cap mates with the outer barrel. 14. The syringe of claim 11, wherein the outer barrel has a distal opening and the inner barrel protrudes through the distal opening when the syringe assembly is fully assembled. 15. The syringe of claim 11, wherein the mating protrusion of the tip cap includes a top surface and a side surface, the side surface being positioned perpendicular to the longitudinal axis of the handle. 16. The syringe of claim 11, wherein the mating protrusion has a triangular cross sectional area. 17. The syringe of claim 11, wherein the tip cap comprises an inner cap, an outer cap, and a connector shaped to fit within and engage the outer cap and engage the inner cap, the tip cap having a plurality of first legs spaced symmetrically away from one another, each first leg having a plurality of internally facing barbs pointing toward a distal region of the connector and each first leg being adapted to engage a proximal region of the inner cap, wherein each of the plurality of internally facing barbs is disposed at an angle with respect to the plurality of first legs. 18. The syringe of claim 17, wherein the tip cap includes a stem portion extending distally from the shoulder having a cylindrical shape. 19. The syringe of claim 18, wherein the inner cap and the connector are received within the stem portion. 20. The syringe of claim 17, wherein the connector includes a plurality of second legs spaced symmetrically away from one another, each second leg having a plurality of externally facing barbs located in the distal region of the connector and adapted to engage a distal region of the outer cap.
