Insulin is a hormone that is produced by beta cells in the pancreas, which is a large organ near your stomach. Insulin is primarily involved with the regulation of blood sugar levels by controlling the break down of food (sugars, fats and proteins) and promoting the absorption of sugar from your blood into your fat, liver and skeletal muscle cells.
You should subcutaneously (under the skin) inject your dose within 15 minutes before the start of your meal or immediately after the meal (within 20 minutes of starting your meal). Suitable injection sites are; the tissue of the upper arm, abdomen, buttocks or thigh.
