BodyBuilders
Insulin promotes glucose storage and is considered by some to be an anabolic hormone. The glucose is converted to glycogen in the tissues and later used up when required. It is this property of insulin which is utilized to promote bursts of energy and muscle build up. Glycogen is always the first substance to be broken down when energy is required. During sports, if one has excess glycogen stored into tissues, this can be immediately released when there is a sudden need. Insulin always makes the body ready in case fuel is needed.
However, the effects of insulin are always counterbalanced by other hormones to make sure that the glycogen storage does not become excessive. The majority of people who take insulin for type 1 diabetics are not fat- thus refuting the belief that insulin can be used to build the body.
Many bodybuilders use insulin in combination in with growth hormone and thyroxine. GH potentiates the anabolic effects of insulin. It is believed that the combination of GH and insulin together act like Growth factors and can stimulate muscle mass growth.
Because bodybuilders take so many other steroids and a cocktail of health supplements, it is difficult to know which drug is causing the increase in muscle mass- but insulin alone does not build the body.
