What does human growth hormone do for your body?
Human growth hormone, or HGH, stimulates and regulates the growth and lifecycle of just about every cell of your body. In terms of biological function, HGH triggers protein synthesis and stimulates lipolysis, or the burning of fat into energy. Human growth hormone may very well be the most important hormone produced by the human body.
Should healthy adults take human growth hormone?
Studies of healthy adults taking human growth hormone are limited. Although it appears that human growth hormone can increase muscle mass and reduce the amount of body fat in healthy older adults, the increase in muscle doesn't translate into increased strength. It isn't clear if human growth hormone might provide other benefits to healthy adults.

People with adult growth hormone deficiency have higher than normal levels of low-density lipoproteins in comparison to their high density lipoproteins. They also tend to have higher triglyceride levels.
How is growth hormone absorbed?
Growth hormone in adults is absorbed quickly by tissues from the blood as it circulates. As a result of this, a blood test given to a healthy persons will show low levels of growth hormone. Endocrinologists instead check the pituitary gland's response when it is stimulated to produce growth hormone.

Where is the secretion of GH hormone regulated?
Secretion of growth hormone (GH) in the pituitary is regulated by the neurosecretory nuclei of the hypothalamus. These cells release the peptides growth hormone-releasing hormone (GHRH or somatocrinin) and growth hormone-inhibiting hormone (GHIH or somatostatin) into the hypophyseal portal venous blood surrounding the pituitary. GH release in the pituitary is primarily determined by the balance of these two peptides, which in turn is affected by many physiological stimulators (e.g., exercise, nutrition, sleep) and inhibitors (e.g., free fatty acids) of GH secretion.

What is a growth hormone stimulating test?
When a deficiency of growth hormone is suspected, a ‘growth hormone stimulating test’ is performed using growth hormone-releasing hormone or other substances, in order to determine the ability of the pituitary gland to release growth hormone. Childhood-onset growth hormone deficiency is associated with growth failure and delayed physical maturity.
What happens if the hypothalamus produces too little growth hormone?
If the hypothalamus produces too little growth hormone-releasing hormone, the production and release of growth hormone from the pituitary gland is impaired, leading to a lack of growth hormone ( growth hormone deficiency ' data-content='1276' >adult-onset growth hormone deficiency).

Biology
Genes for human growth hormone, known as growth hormone 1 (somatotropin; pituitary growth hormone) and growth hormone 2 (placental growth hormone; growth hormone variant), are localized in the q22-24 region of chromosome 17 and are closely related to human chorionic somatomammotropin (also known as placental lactogen) genes. GH, human chorionic somatomammotropin, and prolactin belong to a group of homologous hormones with growth-pro…
Biochemistry
GH has a short biological half-life of about 10 to 20 minutes.
Clinical significance
The most common disease of GH excess is a pituitary tumor composed of somatotroph cells of the anterior pituitary. These somatotroph adenomas are benign and grow slowly, gradually producing more and more GH. For years, the principal clinical problems are those of GH excess. Eventually, the adenoma may become large enough to cause headaches, impair vision by pressure on the optic nerves, or cause deficiency of other pituitary hormones by displacement.
Psychological effects
Several studies, primarily involving patients with GH deficiency, have suggested a crucial role of GH in both mental and emotional well-being and maintaining a high energy level. Adults with GH deficiency often have higher rates of depression than those without. While GH replacement therapy has been proposed to treat depression as a result of GH deficiency, the long-term effects of such therapy are unknown.
