Human Growth Hormone Levels

Normal vs Low HGH Levels

What is Your Real Age when it comes to Growth Hormone?


Maintaining optimal HGH levels is essential to good health in men, women and children. Human Growth Hormone is the principle hormone responsible for normal growth, body maintenance, cell generation, healing and repair. It has a direct impact on how your body uses other important hormones like insulin, thyroid and testosterone. GH helps regulate body temperature, mood, sexual desire, glucose synthesis, lean muscle mass, fat burning and bone strength. Normal base growth hormone (GH) levels in a healthy person range from 5 ng/mL in men, 10 ng/mL in women 20 ng/mL in growing children and adolescents. During extreme exercise and at peaks, growth hormone levels can climb over 20 ng/ml and in some people as high as 45 ng/mL.

Normal HGH Levels

Normal HGH Secretion

Good sleep patterns are important for HGH production. 50% of GH secretion occurs at night during REM sleep in bursts and pulses. Increases in endogenous secretion occur during the day at 3- to 5-hour intervals. Physiological factors known to affect natural HGH production are gender, age, diet, exercise, weight, genetics and other hormones and prescursor hormone like secretagogues that are responsible for stimulating proper release of HGH into the blood stream as needed. Growing children and adolescents have the highest natural levels secreting up to 700 or 800 µg per day. Healthy adult men and women produce HGH at about 400 to 500 µg per day. Since sleep is essential to proper GH release, insomnia or sleep deprivation suppresses normal growth hormone secretion. Read more about HGH production in detail. When testing for levels of growth hormone, laboratories have normal reference ranges endocrine specialists use for measuring growth hormone levels:

  • Normal Lab Reference Levels for Men: 1 to 9 ng/mL (nanograms per milliliter)
  • Normal Lab Reference Levels for Women: 1 to 16 ng/mL (nanograms per milliliter)
Since endogenous GH is released in pulses usually in higher amounts when you sleep, taking random hormone measurements is not as helpful as using the most advanced GH testing methods. Getting your hormone levels tested.

HGH Levels and Aging

Natural Growth Hormone Decline with Age

Human Growth Hormone Declines with Aging. The decline of growth hormone with age is directly associated with many of the symptoms of aging, including cardiovascular disease, increased body fat, muscle loss, osteoporosis, skin wrinkling, gray hair, decreased energy, reduced libido, sexual dysfunction and lack of sexual interest, inability to sleep and other hormone related symptoms. Many of these hormonal symptoms have been found in younger adults who have growth hormone deficiency. In adults low levels of HGH is known as Adult Growth Hormone Deficiency.

HGH Medical Research over the last 40 years confirms the decline of HGH as men and women reach well into adult years and the decline of HGH production accelerates. Age Management Doctors and Anti-Aging Medicine Physicians theorize that as people get older, the endocrine system does not function as well and therefore people get older because their hormones begin to decline. After the age of 30 your body no longer stimulates at the same pace the regeneration of new healthy cells to replace the cells that are dying off. Since your body is unable to renew its cells quick enough, maintenance and repair fall behind - aging seems to be the process of your body slowly dying faster than it can replace itself.

As the cell renewal process becomes less and less efficient, the dying process accelerates as you continue to age. Read more about HGH decline in adults and the subsequent symptoms caused by hormone insufficiency - Low HGH Symptoms

HGH Levels During Your Life

HGH is at its highest level when you are growing and peak during adolescence until about 20 year of age. After age 20, your growth hormone levels fall fall off from 10% to 15% each decade. By 60 years old you are either partially or completely deficient in the HGH hormone. Age is therefore, a major factor in your measuring this most important hormone and lack of it a cause of age-related disease, and signs and symptoms caused by menopause and andropause. Adults with lower than normal hormone levels can feel the negative effects as their normally daily level of 500 micrograms of growth hormone is reduced to a mere 200 micrograms at age 40, 100 micrograms by the age 60, and only 25 micrograms by the age 80. read more about the impact of Adult Growth Hormone Deficiency

Human Growth Hormone Decreases significantly after the age of 35 to 45, and that by the age of 40, your HGH production is down to 50% of the levels you produced daily in your youth. By the age of 55 to 60, it sinks even further to 20% which is not much more than someone in their 80's can naturally produce. By the time most adults reach 45, age-related signs and symptoms caused by growth hormone deficiency start to appear. Other than Hypopituitary disorders where the pituitary gland is impaired, medical scientists do not know the exact reason why persons over the age 35 to 45 tend to incur such a significant natural decrease in HGH growth hormone secretion from the pituitary gland, with the result causing symptoms of aging, andropause, menopaue and human growth hormone deficiency.

Somatotroph Cells still healthy in middle age. Medical research has revealed that the aging pituitary somatotroph cells can still secrete as much growth hormone as the young somatotrophs cells if they are properly and adequately stimulated. As a result some medical researchers have come up with several theories regarding aging resulting from HGH related deficiency including an increase of HGH blockers paired with a decline in function of the specialized receptor cells needed to bind to growth hormone and deliver it to their designated cells and tissues. With HGH supplementation to replace lost hormone levels, there are 60 to 70 year olds with biomarkers reflecting the physiological bodies of those less than half their age. This allows adult men and women to normalize and optimize their hormone levels to live a healthier and more youthful life.

Nearly fifty percent of GH secretion occurs during the third and fourth NREM sleep stages. Surges of secretion during the day occur at 3- to 5-hour intervals. The plasma concentration of GH during these peaks may range from 5 to even 45 ng/mL. Between the peaks, basal GH levels are low, usually less than 5 ng/mL for most of the day and night. Additional analysis of the pulsatile profile of GH described in all cases less than 1 ng/ml for basal levels while maximum peaks were situated around 10-20 ng/mL. A number of factors are known to affect GH secretion, such as age, sex, diet, exercise, stress, and other hormones. Young adolescents secrete GH at the rate of about 700 µg/day, while healthy adults secrete GH at the rate of about 400 µg/day. Sleep deprivation generally suppresses GH release, particularly after early adulthood.

Why HGH Levels Decline

HGH Blockers Increase with Age

HGH “Blockers”, called Somatostatins, increase with age while hormone receptor cells lose their functionality with age. Some research scientists believe the problem of GH level decline lies with the increase in somatostatin levels which are the natural inhibitors or HGH blockers. Elevated somatostatin has been found to increase in population within the body with age and may act to block the pituitary’s release of natural HGH Human Growth Hormone. When researchers eliminated somatostatin production in old rats, they found growth hormone secretion at similar levels as those of young rats. This might indicate theoretically that the pituitary gland has a life long ability to produce any healthy level of HGH we require as long as the body's specialized receptor cells are functioning and HGH blockers are mitigated or removed.

HGH Stimulators and Releasers Decrease with Age

Growth Hormone Releasing Hormone. A second theory impacting GH levels is that the precursor hormone, growth hormone-releasing hormone (GH-RH), which stimulates hgh human growth hormone release by the pituitary gland, becomes less sensitive to signals from the hypothalamus. Hence, insufficient GH-RH is released resulting in a decrease of growth hormone secretions over time and age. Age Management Physicians and Hormone Therapy Doctors are able to prescribe HGH releasers such as Sermorelin to help boost HGH levels - Hormone Therapy can use HGH Sermorelin Injections to Boost Growth Hormone Levels

Decreased Ability of the Body to Process HGH

The Body Requires More HGH as we Age as the Body loses its ability to actually utilize HGH.

Not only does the growth hormone secreted and available to receptors in our cells decrease with aging, but that the cell receptors become more resistant and less responsive to the human growth hormone. Under this theory, aging can be viewed as a disease of growth hormone resistance within our cell receptors similar to the way in which diabetes is a disease of insulin resistance.

Boosting HGH Levels

The best way to treat GH deficiency symptoms including recombinant HGH somatropin injections, peptide releasing agents sermorelin, GHRH, GHRP, injectable IGF-1 amino acids. Studies have clearly shown that the injectable form of treatment far surpasses any oral or topical form of growth hormone stimulation or supplementation. Besides taking rHGH somatropin injections to replace lost growth hormone, your doctor can consider prescribing HGH releasers like Sermorelin Actetate, IGF-1, GHRP, testosterone and amino acid supplements to boost endogenous growth hormone levels. Human growth hormone has been shown to help build muscle, enhance libido, increase energy and stamina, help your body repair itself and heal faster, make your hair and nails grow faster, reduce body fat, improve mood and sleep. Some people who ask if you want to stay looking and feeling young forever, say you should learn how to keep your HGH levels high to the slow and even reverse the aging process.

HGH is a protein made up of 191 amino acids secreted by the pituitary gland independently in the brain. As the master hormone it plays a dominant role in the human body and endocrine system. it regulates other hormones, tissue and organ repair, cell reproduction and bodily functions. The human growth hormone is secreted by the pituitary gland and carried to organs, tissues and cells throughout the body. Intense exercise and during sleep is the time that its production is at its highest. Recombinant DNA Somatropin or HGH Injections is used in replacement therapy to alleviate hormonal symptoms by normalizing GH levels.

Symptoms of Low Human Growth Hormone

Signs that you are Low in Growth Hormone and How to Boost Low Levels

HGH Levels that are low reflect a hormone deficiency. Menopause symptoms in women and andropause symptoms in men are a sign of adult human growth hormone deficiency. The initial symptom that hormone levels are low is the lack of energy despite sleeping at night. This is true in both men and women. Eventually low HGH affects sleep patterns and the ability to get a good night's rest is significantly impaired. Since most HGH is secreted and released into the blood stream during sleep, inability to sleep well exacerbates the natural HGH production process. Feeling tired all day and a sense of lethargy overtaking your daily life is usually one of the first noticeable symptoms. A greatly reduced sex life is another sign that HGH and testosterone levels may be low. Most patients and their general physicians are unaware that their symptoms might be due to insufficient hormones whether it be testosterone, thyroid or growth hormone. That is why using an experienced hormone specialist or Age Management Physician acquainted with bio-identical hormone therapy can help you discover what is causing your health symptoms. Through a doctor-prescribed GH replacement program using genuine somatropin injectables you can replenish you hormone levels and get back to living your life to the fullest.

HGH Lab Test Note: Endogenous HGH is released in pulses making random Growth Hormone testing measurements not very useful. A higher GH level may be normal if the blood was drawn during a pulse. A lower level may be "normal" if the blood was drawn around the end of a pulse. Fasting before a test and taking it earlier in the morning at the same interval can help mitigate the effects and disadvantages of random lab testing for this hormone. GH is most useful when measured as part of a stimulation or suppression test. For this reason many HRT physicians will order an IGF-1 panel to help measure HGH levels as these two hormonal substances correlate with IGF-1 not being greatky impacted by random blood testing. Normal reference value ranges may vary slightly among different laboratories for example Access Labs vs Labcorp vs Quest Diagnostics. Some labs use different measurements or test different specimens.
