Nestled in the center of our heads there sits a rather tiny but very powerful gland called the pituitary gland. Hgh is one of 7 hormones secreted by the pituitary. Growth hormone, like thyroid hormone, has an effect on almost all our tissues and organs. As the name implies, it enhances the growth of various organs and tissues, especially muscle and bone. Basically, human growth hormone increases protein synthesis.
Proteins are the major building block out of which our body is made.
Normal secretion of Hgh occurs in a daily cycle, like a tide. It varies with exercise, sleep, stress and nutrition. As we hit middle age, there is a natural decline in hormone production, not only of Hgh, but estrogen, progesterone, DHEA, androstenedione, and testosterone. Also, central obesity increases and muscles shrink. Scientific studies are demonstrating a causal relationship between the decline in hormone levels and an increased incidence of the aforementioned conditions.
