Physicians world wide now consider aging a biological process that can be modified and improved to combat the symptoms of aging. Anyone who wants to maintain their youthful vigor and vitality should consider raising their human growth hormone level as part of their health program. Until now, improving one's level of HGH has been available only by injections and limited to only very wealthy people. But now, after considerable use and testing, Longevity4 is available to raise one's level of human growth hormone to youthful levels, at very moderate cost.  It is possible to reverse aging, to dramatically improve all aspects of health, vitality and longevity.... Longevity4™ the natural way to increase the level of human growth hormone.

The Ingredients
Arginine, Glutamine, Ornithine, Glycine, & Pepsin

1. Arginine: The GH-Provocateur
What is it:
An essential amino acid, meaning that the body cannot create this amino acid on its own but must get it from the foods we eat.

Effects on GH ( Growth Hormone)
There is no doubt that arginine causes the secretion of growth hormone. A 15 to 30 gram intravenous infusion of arginine is used as a standard endocrinological test to provoke the pituitary to release growth hormone. Dirk Pearson and Sandy Shaw recommended arginine and ornithie as GH- releasers in their first book Life Extension: A Practical Approach, turning these amino acids in to best-selling nutrients that disappeared from the shelves quicker that cranberry sauce Thanksgiving.   A number of clinical studies on various doses of arginine and arginine in combination with lysine have shown widely varying effects on growth hormone including synergistic increase in GH. 

Anti aging benefits 
Positive claims for arginine include increasing fat burning and building muscle tissue probably through the stimulation of growth hormone, increasing the weight and activity of the thymus gland, boosting immunity, fighting cancer, promoting healing of burns and other wounds, protecting the liver and detoxifying harmful substances, and enhancing male fertility (almost all of which are enhanced by GH). It also restores sexual function in impotent men. In a 1994 study by doctors. A.W. Zorgniotti and E.F. Lizza of the department of urology/surgery at New York University School of Medicine, six of fifteen men who took 2,800 milligrams of arginine a day for two weeks had renewed sexual performance, specifically improved erection, yet none of the men on the placebo did. The researchers believe that arginine worked because it is a precursor of nitric oxide, which plays a key role in initiating and maintaining an erection. 

2 Glutamine
What is it:

Glutamine is the latest amino acid to generate excitement as a GH-releaser thanks to a 1995 study by Thomas C. Welbourne of Louisiana State University College of medicine in Shreveport, Welbourne showed that a surprisingly small oral dose of about 2 grams of glutamine raised growth hormone levels more than four times over that of a placebo. Even more exciting, age did not diminish the response at least in this small study of volunteers, who ranged from thirty-two to sixty-four years.

Anti aging benefits
Glutamine is the amino acid that is most used by the body, particularly during times of stress. The immune system and the gut practically live on glutamine. If the body does not produce enough glutamine, muscle loss and immune dysfunction can occur. The gut atrophies, meaning nutrients all kinds cannot be absorbed as well as before. A 1993 study by Welbourne in animals showed that glutamine supplementation protects muscle mass and prevents acidosis, which occurs with strenuous exercise and causes muscle breakdown. According to Judy Shabert, M.D. author of The Ultimate Nutrient Glutamine, supplementation with glutamine, especially in times of stress, would prevent muscle wasting. In a foreword to the book, Douglas Wilmore, M.D. , of Harvard Medical School, points out that glutamine is a key to the metabolism and maintenance of muscle, the primary energy source for the immune system, and essential for DNA synthesis, cell division, and cell growth, all factors that are enhanced by GH. It also crosses the blood-brain barrier into the brain, where it increases energy and mental alertness.

3 Glycine: Exercise Enhancer
What it is
A nonessential amino acid Two studies found that this amino acid increases growth hormone in the serum. In one, 6.75 grams at bedtime caused an three-fold increase, while a Japanese research team showed that 30 grams raised growth hormone levels ten times over baseline in patients who had gastric surgery.

Anti aging benefits
May be useful in dampening hyperactive brain activity that produces spasms. In one study, 1 gram of glycine a day for six months to one year significantly reduced spasms in all ten patients with severe chronic spasticity in the legs, including seven with multiple sclerosis.

4 Ornithine
What it is
This is strictly speaking not an amino acid, but a French designer nutrient that consists of ornithine bound two molecules of alpha ketogutarate, which is a precursor to glutamine and has GH-stimulating effects. It boosts glutamine levels even more that glutamine itself.

Effects on GH
OKG in doses of 10 grams or more was more effective than either ornithine or alpha ketogutarate in raising GH release several fold in a majority of normal subjects.

5 Pepsin
What it is
Pepsin is a principle enzyme. It controls the degradation of proteins and aides in the secretion of proteins.

Anti-aging benefits
Combined with Amino Acids nutrients, causes a greater frequency and amplitude of human growth hormone release.


Clinical Study

Clinical Study : Longevity (L-4)
Conducted by Dr. Essman, Endocrinologist, 

Date started on treatment: August 1, 1999
Date finished treatment: October 1, 1999

After 30 years of aging, levels of human growth hormone substantially decrease.  Low levels of human growth hormone are directly associated with the many diseases associated with the aging process.  Raised levels of HgH have produced health improvements and benefits.  Dietary supplements composed of amino acids have been shown to promote the secretion of human growth hormone release.   Pepsin has been shown to increase the amplitude and frequency of HgH release, in addition to amino acids.  Arginine has been shown to diminish the effects of somatistatin, which is produced by the pituitary gland and inhibits human growth hormone from being distributed.  Human growth hormone immediately changes into IGF-1 as we sleep.  Increased IGF-1 levels indicate that human growth hormone have raised correspondingly.
