Your body naturally makes human growth hormone (HGH) to help with growth and maintaining your body's tissues, bones and muscles throughout your life. The pituitary gland, which is considered the body's "master gland", is a small gland at the base of your brain that produces this hormone.

Since this gland is far more active in childhood than it is later in life there is a vital relationship between human growth hormone and the aging process. As the body produces and releases less and less HGH we begin to feel many undesirable symptoms, which we know as aging. These symptoms can include less energy, reduced muscle mass, more difficulty in exercising, increased body fat, decreased bone density, anxiety, moodiness, and many others.

Many clinical studies suggest that getting more of this hormone produced and released through our body may be able to reverse many of these aging symptoms. Studies have shown that HGH supplementation can increase bone density, increase muscle mass, decrease body fat and improve ability to exercise and reduce many other physical and mental symptoms of aging in adults who were previously deficient in HGH.

HGH can come in an injectable form that requires a prescription from a doctor and is very expensive and can run up to $1,000 per month when you consider all the doctor's visits necessary to monitor your progress. The injectable form usually contains high levels of synthetic human growth hormone and is also obviously an invasive and quite unnatural therapy. A few of the least frightening side effects of these injections include joint pain carpel tunnel syndrome and fluid retention and in some cases the user's pituitary gland can stop working properly.

But what if we could get the body to produce more of its own, natural growth hormone like it did in our twenties and thirties through a natural, non-evasive means. This would truly be a miracle. And it has happened.

Instead of getting synthetic, intramuscular injections like many athletes do illegally to increase levels of growth hormone, scientists have found a way to provide the body with the precursors and secretagogues in order to support and maintain a healthy endocrine system that includes the release of human growth hormone by the body's master gland, pituitary gland.

So what are secretagogues and precursors?

According to the Wikipedia a secretagogue is a substance which causes another substance to be secreted. For instance the substance gastrin causes the secretion of gastric acid by the stomach. Any oral agent that is meant to assist the pituitary in the release more of your body's own human growth hormone is referred to as a secretagogue.

According to the American Heritage Dictionary a precursor is "A biochemical substance, such as an intermediate compound in a chain of enzymatic reactions, from which a more stable or definitive product is formed: a precursor of insulin." In other words if you give the body a nutrient which will help it produce a needed substance such as HGH that nutrient could be called an HGH precursor.

Some of the most powerful of these HGH secretagogues and precursors include: amino acids such as L-Lysine, L-Arginine, Ornithine, L-Glutamine, Gamma-Amino Butyric Acid (GABA) and Glycine. The vitamin niacin has also been found to be a proven HGH releaser.

It is important to have the right formulation and quality of these supplements to have them act as secretagogues so you know you are getting the best benefits possible. Just adding these ingredients in random amounts will not be effective you need a well researched formulation of these substances.

By supplying the body with the proper nutrients you can help it produce this incredibly valuable hormone and increase your body's strength, decrease body fat and feel and look younger. You can get that anti-aging miracle.
