Insulin is typically administered subcutaneously (under the skin) for several reasons:

1. *Absorption*: Subcutaneous tissue has a rich blood supply, allowing for rapid absorption of insulin into the bloodstream.
2. *Convenience*: Subcutaneous injections are relatively easy to administer, and patients can self-inject with minimal training.
3. *Safety*: Subcutaneous injections are generally safer than intravenous or intramuscular injections, with less risk of infection or other complications.
4. *Steady absorption*: Subcutaneous tissue provides a steady and consistent absorption of insulin, which helps to maintain stable blood sugar levels.
5. *Less pain*: Subcutaneous injections are often less painful than other injection routes, making them a more comfortable option for patients.
6. *Easy to access*: Subcutaneous tissue is easily accessible, making it a convenient location for injections.
7. *Reduced risk of hypoglycemia*: Subcutaneous injections reduce the risk of hypoglycemia (low blood sugar) compared to intravenous or intramuscular injections.

Overall, subcutaneous injection is a convenient, safe, and effective way to administer insulin, making it a popular choice for people with diabetes.
