The following represents a summary of how Human Growth Hormone, HGH influences physiological processes to promote a youthful vigor:
HGH or Human Growth Hormone (also called somatotrophin) is produced
in the anterior of the pituitary gland deep inside the brain, where
it is one of the most abundant hormones secreted.
It influences the growth of cells, bones, muscles and organs throughout
the body. Production peaks at adolescence when accelerated growth occurs.
If growing children have too little they remain as dwarfs, while if
they have too much they become giants.
HGH is one of many endocrine hormones, like estrogen, progesterone,
testosterone, melatonin and DHEA, that all decline in production with
age. While many of these hormones can be replaced to deter some of the
effects of aging, HGH reaches far beyond the scope of any of these hormones.
Not only does it prevent biological aging, but also it acts to significantly
reverse a broad range of the signs and symptoms associated with the
aging process.
Human Growth Hormone is a polypeptide hormone composed of a long chain
of 191 amino acids. Under normal physiologic conditions, Growth Hormone
is secreted by the anterior pituitary gland. This is a gland that lies
at the base of the brain in a bony cavity called the Sella Turcica.
In addition to Growth Hormone, the anterior pituitary also secretes
prolactin, follicle stimulating hormone, thyroid stimulating hormone,
luteinizing hormone and adrenal corticotropic hormone.
The secretion of Growth Hormone by the pituitary gland is initiated
by the hypothalamus, another gland in the brain that lies right next
to the pituitary. The hypothalamus initiates Growth Hormone secretion
by secreting Growth Hormone releasing hormone (GHRH); at the same time
it stops secreting a Growth Hormone inhibitory hormone called somatostatin.
When somatostatin is turned off and GHRH is turned on, the pituitary
will release Growth Hormone in different bursts of activity. These bursts
of Growth Hormone release occur primarily during deep stages of sleep,
such as stage 3 and stage 4. Once released in the blood, Growth Hormone
is very short lived. In fact, HGH or Human Growth Hormone is generally
completely metabolized and gone within a half-hour. During this period,
however, Human Growth Hormone manages to reach the liver and many other
cells in the body, and induce them to make another polypeptide hormone
called Insulin-like Growth Factor One (IGF-1). It is really IGF-1 that
travels around to the various tissues of the body to effect most of
the benefits that we attribute to Growth Hormone.

The secretion of Growth Hormone itself is regulated by a classic biofeedback
loop. Hence when levels of Growth Hormone in the blood reach a certain
threshold, Growth Hormone stimulates receptors in the pituitary to stop
further Growth Hormone secretion. It also stimulates receptors in the
hypothalamus to stop GHRH and turn on somatostatin. IGF-1, which goes
up in response to Growth Hormone, also feeds back on the pituitary and
hypothalamus to help control Growth Hormone secretion.

Growth Hormone plays a major in stimulating body growth by signaling
the liver and other tissues to secrete IGF-1:
In addition, Growth Hormone has important effects on carbohydrate
lipid (fat) and protein metabolism:
Decline in Human Growth Hormone with age


Human
Growth Hormone is secreted by the pituitary gland were the Human Growth
Hormone levels peak during adolescence. Human Growth hormone levels subsequently
decreases with age. The levels of human Growth Hormone after age 30 declines
approximately 15% per decade. Generally, we produce approximately 500
micrograms of human Growth Hormone daily at age twenty, 200 micrograms
at age forty, and only 25 micrograms at age eighty. Secondary to the natural
decrease in human Growth Hormone production by age forty we are producing
only some forty percent of what we produced at age twenty. Now with advent
of Human Growth Hormone supplements like Physicians' Select Human Growth
Hormone Supplements we can now see markedly increased levels of Human
Growth Hormone.

Fortunately, with the advances in science we can now increase
human Growth Hormone levels. Secondary to increasing Growth Hormone levels
we can now expect a much improved quality of life including the following:
