"Tuberculin" syringes and types of syringes used to inject insulin are commonly used. Commonly used syringes usually have a built-in 28 gauge (or thereabouts) needle typically 1/2 or 5/8 inches long. The preferred injection site is the crook of the elbow (i.e., the Median cubital vein), on the user's non-writing hand.
