Insulin represents a hormone that control level of glucose and is regulating fat metabolism in the body. In natural form this hormone is secreted from the pancreas.
It is widely used in medicine for treating different forms of diabetes mellitus. This disease appears at time when control of insulin in human body fails. Insulin is administered by injection under the skin (subcutaneously).
Insulin is considered to be the most anabolic hormone produced by the body. Bodybuilders and athletes consider this drug good choose in case the goal is to gain mass. For some years insulin became very popular in bodybuilding because of its anabolic effects.

How Insulin Stimulates Fat Cells to Take in Glucose
ScienceDaily – Using high-resolution microscopy, researchers at the National Institutes of Health have shown how insulin prompts fat cells to take in glucose in a rat model. The findings were reported in the Sept. 8 issue of the journal Cell Metabolism.
By studying the surface of healthy, live fat cells in rats, researchers were able to understand the process by which cells take in glucose. Next, they plan to observe the fat cells of people with varying degrees of insulin sensitivity, including insulin resistance-considered a precursor to type 2 diabetes. These observations may help identify the interval when someone becomes at risk for developing diabetes.
“What we’re doing here is actually trying to understand how glucose transporter proteins called GLUT4 work in normal, insulin-sensitive cells,” said Karin G. Stenkula, Ph.D., a researcher at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) and a lead author of the paper.
