Some 80% of the insulin reaching the liver is cleared from the circulation, which means that insulin attains much higher concentrations in the liver than in the peripheral circulation. Insulin has a short plasma half-life (3-4 minutes), and choice of the route and timing of insulin administration is a major determinant of metabolic control. Conventional insulin injections are given into the thigh, abdomen or outer side of the buttock. Standard needles range from 0.8 - 1.6 cm in length, are used with a syringe or pen device and deliver insulin into the subcutaneous fat.

Many alternative routes of administration have been tested, but none can match direct injection or infusion.
