This article discusses in detail the functions of the Human Growth Hormone
HGH means Human Growth Hormone. It is also known as somatotropin or somatropin. It is made up of protein chains known as peptides. People mainly think of using this hormone for extra growth and try to become youthful, but is not realistic. Researches show that it is not useful for becoming youthful and it can cause harmful effects in the body when tried for the same.
Pituitary gland of the body produces this hormone. It promotes growth both in adults and children. Different biological activities such as various composition of the body, fluids of the body, growth of skeletal muscle tissue, bone growth, metabolism of different metabolites such as blood sugar and adipose tissue are maintained by growth hormone in our body. It also increases the fat accumulation in the body. Blood sugar level is enhanced in body due to higher concentration of the growth hormone. Some times it also maintains the function of the heart. It is also produced synthetically in the laboratory and used in the manufacturing of different varieties of drugs.
Structure of Growth Hormone:
It has 191 peptide chains in its structure. It is produced, stored and released from anterior pituitary gland. It is commonly prescribed by doctors for children and adolescents.
What Is Pituitary Gland?
It is one of the glands situated in the base of the brain. Its size and shape is like a pea. It is also known as hypophysis. Its weight is about 0.5 g. It is one of the endocrine glands of our body. The front part of the pituitary gland regulates stress, reproductive system, lactation process, growth of skeletal tissues. Middle lobe of the pituitary gland produces and releases melanocyte stimulating hormone which provides color to the skin. Skin color totally depends upon melanocytes. Back part does not synthesize any hormones. It stores antidiuretic and oxytocin hormone.

Increased and Decreased Levels of the growth hormone:
There is a test to diagnose the concentration of the amount of the growth hormone in blood. Blood sample is taken from the vein of the patient from hand. Excess amount of growth hormone in blood causes over growth of the muscle and bones. This condition is known as acromegaly. It mainly occurs in adults people. In children, it is referred as gigantism. If concentration of the hormone is low in blood, it causes under growth or limited growth of the body tissue. It mainly affects skeletal tissue, cholesterol level in blood, and strength of the bone in patients. Test is also used to observe that the treatment for acromegaly works or not.
Excess of the hormonal levels - it produces several symptoms such as visual impairment due to over pressure on the optic nerve which is responsible for vision, severe headache, it also increases the thickness of the bone. Bones of fingers, toe, and jaw bones are most commonly are affected. Acromegaly has all these symptoms. There are many other symptoms such as heaviness in jaw. Fingers become longer than normal. Profound sweating is also present. Sometimes pressure on the hand nerve may cause carpal tunnel syndrome. Carpal tunnel syndrome means heaviness, tingling, numbness present over affected hand due to pressure over the median nerve of the hand. Median nerve is a main nerve responsible for hand and finger functions. Sometimes, sexual function may reduce. Nerve and muscle pain is also produced. Swelling in the peripheral extremity may be present with the high level. Enlargement of the breast tissue in the men becomes evident.
Deficiency - signs and symptoms may depend upon the age. Short height and growth failure are the main symptoms of the deficiency of the growth hormone. Defects from birth are also present. Delayed sexual maturity is one of the prime symptoms. Increment in fat tissue, reduction in muscle fibre count, reduction in energy and this may hamper the quality of the life.

How to Use HGH Safely?
In early 19s, GH was highly used for enhancing the performance of the athletes in different sports activities. So, it was banned during that time since it is not detected in urine test. But in early 20s, it was best diagnosed from blood test. Food and drug administration department does not approve this drug. Livestock production in agriculture industries also used growth hormone.
It is applied by injection directly under the skin. Growth hormone pills and dietary supplements are available in market nowadays, but they are not effective as injected drugs. Artificial growth hormone has to be protected from light and heat rays. 36 to 46 degree Fahrenheit temperature is essential for storage of growth hormone in lab.
3.0 cc syringes are used for injection. Bacteriostatic water is filled in syringe. After that human growth hormone bottle should be opened. Powder of HGH is filled into syringe. Doctor or health care provider should not shake the syringe. When this powder is well mixed with protein water, the fluid will become clear in texture. Cloudy mixture is not administered in the body. Mixture should be filled up to 40.0 units. 2 IU is the exact amount of HGH in this mixture. This mixture should be injected in the inner part of the thigh subcutaneously. Please take it before sleep, because it increases the efficacy of the drug.
