Hormone Replacement Therapy > HGH Declines with Aging

The decline of growth hormone and IGF-1 levels with age is directly associated with many of the symptoms of aging, including cardiovascular disease, increased body fat, osteoporosis, thin skin, age spots, wrinkling, gray hair, decreased energy, reduced sexual function and interest, and other aging archetypal symptoms. Many of these same age related symptoms have been found in younger adults who have growth hormone deficiency.

Research over the last 40 years confirms the decline of HGH as we age in our adult years and unfortunately the decline of HGH production in our bodies accelerates as we get older. As we continue to get older each year after the age of 25, our bodies are not stimulating the regenerating new healthy cells as fast as they are dying off, and as a net result, aging seems to be the process of our bodies slowly dying faster than it can replace itself or recover from damage and stress. The slow dying process in humans accelerates as we continue to age.

HGH is produced at a rate that peaks during adolescence when accelerated growth occurs. Growth hormone secretion decreases with age in every animal species tested thus far. In humans, the amount of growth hormone after age of 25 to 30 declines about 14% per decade (or 1% to 2% per year), so that total daily growth hormone production is reduced dramatically with age. In numerical values, we produce on a daily basis about 500 micrograms of growth hormone at age 20, 200 micrograms at age 40, and 25 micrograms at age 80. At age 40 our growth hormone production is only 40% of what we produced at age 20. The fall in IGF-1 levels with age is identical to the decline of growth hormone.

Another research study has shown that by the age of 40, our HGH production is down to 50% of youthful levels. By the age of 55 it sinks to 20%, which is not much more than someone in their 80's can produce. Click below to continue......
