Growth hormone produced in the pituitary gland and is essential for normal growth and development. Growth hormone excretion is increased by various types of mental and physical stress, and physical activity.

The excretion of growth hormone are highest in late adolescence, when growth is greatest, and growth hormone production decreases gradually with increasing age.

Growth HormoneAlthough the body’s own growth hormone produced is essential for normal muscle growth and development, it is not certain evidence that additional supply of growth hormone from the outside has a greater effect on muscle growth. It is possible that large doses of growth hormone used as doping, combined with exercise, can help increase muscle mass, but such doses can also cause potentially serious and permanent side effects.

Side Effects

The most common side effects of growth hormone used in large doses doping:

Cardiovascular disease

Growth hormone use leads to a risk of higher blood pressure, a major cause of heart disease. The heart can grow over time, which means that the heart muscle becomes less elastic, and the heart’s pumping ability is reduced.

Internal organs

Growth hormone increases the growth of internal organs and fluid accumulation in the tissues.

Muscles and bones

The bones, especially in the head and facial bones begin to grow even after puberty and normal length growth is completed. This can lead to the need for braces as an adult, because the bite changes. Nose, ears, hands and feet can also grow. Increased amount of growth hormone can also provide joint and muscle pain and decreased nerve function.


Growth hormone increases the risk of type 2 diabetes (“age diabetes”).


Prolonged abuse can increase the risk of cancer, especially of the gastrointestinal intestinal tract.

Skin and hair

Growth hormone increases body hair, increased sweating and oily skin.


Acromegaly is a collection of those symptoms that occur when using an increased amount of growth hormone over time. Several of the listed side effects are included in this clinical picture. The changes occur slowly and can often not be seen until it has been a long time. Acromegaly gives users a distinctive look.
