What Does HGH Do

Human growth hormone (hGH) is a peptide hormone, consisting of 191 amino acids, produced by the pituitary gland.

It plays a central role in several key bodily functions, impacting not only growth in children, but also your metabolism, muscle mass, and bone density as an adult.

Thus, this hormone is crucial for individuals of all ages, influencing numerous physiological processes essential for health.

In this article, we delve into the multifaceted roles of hGH and examine how it governs these complex systems.

You will also discover the potential benefits of hGH therapy, emphasizing its importance not just as a growth regulator but as a significant contributor to overall well-being.

Understanding The Role of hGH In The Body

HGH is secreted by the pituitary gland and is essential in both males and females. It plays a crucial role in the growth and development of children and teenagers. Additionally, adults require this hormone to manage diverse metabolic functions.

Normally, human growth hormone is produced in pulses, which means its levels peak and plummet on a daily basis. Usually, peaks happen once or several times in 24 hours, and serum hGH levels can be undetectable in between them.

hGH exerts both anabolic and catabolic effects:

• The catabolic ones are mediated directly by hGH on fat tissue, particularly on fat deposits around the abdomen.
• The anabolic ones are mediated by stimulating the production of an insulin-like hormone in the liver and other tissues called IGF-1. It is the main mediator of hGH’s anabolic effects.

IGF-1 levels depend on the mean hGH levels and don’t have the same pulsatile secretion. Consequently, there are scientifically determined reference ranges for both men and women according to age. In fact, both hGH and IGF-1 synthesis decline with age.

The anabolic effects of hGH, exerted through IGF-1 primarily affect growth, cellular proliferation, muscle anabolism, and bone density.

In addition, hGH is in a complex interaction with several other hormones and may influence energy levels, mood, sexual function, and more.

What Does hGH Do For Females?

As mentioned, hGH is produced in pulses, and studies suggest that females may have a higher pulse size, pulse frequency, and mean daily human growth hormone levels compared to men.

More specifically, research suggests hGH in women may reach up to 14 ng/mL (630 pmol/L) during a peak. That is likely due to the antagonistic effects of female hormones such as estrogens on hGH’s effects.

Researchers suggest that estrogen may have a direct stimulating effect on hGH secretion. Some scientists also claim that estrogen inhibits the liver production of serum IGF-1 levels. Consequently, the pituitary gland is forced to produce more hGH to maintain normal IGF-1.

As mentioned, hGH plays an important role in stimulating fat breakdown, especially targeting belly fat and visceral fat.

Its anabolic properties also enhance cellular division and regeneration. Notably, hGH is essential for maintaining healthy skin due to its role in promoting skin renewal. This is supported by research suggesting the presence of hGH receptors in the skin, which are instrumental in triggering regenerative processes.

Studies also indicate that hGH is necessary for the development and upkeep of healthy bone mineral density, playing a potential role in reducing the likelihood of bone fractures. This is particularly significant for groups prone to bone loss and osteoporosis, such as postmenopausal women.

What Does hGH Do For Males?

Physiological levels of hGH are typically lower in healthy men than in healthy women, yet men often show greater responsiveness to growth hormone therapies. Typically, normal peak hGH levels in men reach up to 10 ng/mL (450 pmol/L).

hGH is thought to contribute to the regulation of energy and mood. Additionally, it assists in supporting a more favorable body composition in men by differently affecting muscle and fat tissues. The hormone’s anabolic properties enhance protein metabolism and help prevent muscle degradation. At the same time, it promotes the breakdown of fat through a process known as lipolysis.

Beyond influencing body composition, hGH plays a role in male sexual health, impacting potency and libido. Research indicates the presence of hGH receptors in reproductive tissues.

In vitro experiments suggest that hGH could affect the production of sex hormones in the testicles. Moreover, preliminary studies indicate a potential role for hGH in enhancing male sexual arousal and sustaining normal erectile function.

Signs and Symptoms of hGH Deficiency

Growth hormone deficiency (GHD) is a condition where the pituitary gland no longer produces sufficient amounts of hGH. Statistics suggest that the condition affects about 1-3 per 10,000 adults and it may occur at different stages in life.

More specifically, it can be classified into three groups based on the time of onset and the specific cause:

• congenital, which is present since birth due to genetic mutations;
• idiopathic, with an unknown cause and typically beginning in childhood;
• acquired, which occurs due to identifiable reasons after birth.

The majority of adult-onset GHD cases are acquired, commonly caused by factors such as tumors, brain surgery, ionizing radiation, severe head trauma, brain infections, or infarction of the pituitary gland. A small percentage of adult cases are idiopathic, where the cause remains undetermined by modern medicine.

In men, the most noticeable symptom of GHD is the accumulation of visceral fat, which can lead to serious metabolic diseases like type 2 diabetes and increase the risk of heart disease.

Men may also experience decreased sexual desire, erectile dysfunction, loss of muscle mass, and chronic fatigue.

GHD may also profoundly affect mental health, with depression and social isolation being common among both men and women who are affected.

As noted, women exhibit higher hGH levels due to estrogen’s stimulating effects. However, hGH levels often decline during menopause, with both conditions contributing to weight gain, reduced bone density, and mood fluctuations.

Furthermore, research indicates that weight gain during menopause can significantly increase the risk of heart issues in women, especially if it is visceral fat gain due to additional GHD.

For menopausal women undergoing hormone replacement therapy with estrogen, an adjustment in human growth hormone dosage might be necessary. Despite estrogen’s ability to stimulate hGH, it does not prolong its peak levels and also inhibits the production of IGF-1. Consequently, a higher hGH dose may be essential to maintain normal IGF-1 levels during therapy.

Treating hGH Deficiencies

Administering exogenous hGH as a prescribed medication is recognized as the most effective method for addressing the symptoms of growth hormone deficiency. This treatment, known as hGH therapy, involves the daily use of this hormone.

The hGH employed in this treatment is generated through recombinant DNA technology, which produces a hormone identical to the one naturally secreted in humans, referred to as recombinant human growth hormone or somatropin.

Once in the bloodstream, recombinant hGH mimics the natural hormone’s effects, making it safe for use by both men and women under a doctor’s supervision.

Physicians monitor and adjust the hGH dosage carefully to ensure both the safety and efficacy of the treatment.

The starting dosage typically begins at a minimal 0.2 mg per day, gradually increasing to a level that maximizes benefits while minimizing potential side effects.

Legally, recombinant hGH is only available with a prescription authorized by a medical professional.

The following outlines the expected progress during the first six months of hGH therapy, based on various studies:

• In the first month, trials suggest that IGF-1 levels peak, potentially enhancing cell regeneration, hair growth, and muscle gains.

• By the third month, studies suggest that increases in muscle mass and decreases in abdominal fat become more noticeable, alongside improved cholesterol levels due to visceral fat loss.

• The sixth month may see further improvements in body composition. Research indicates significant enhancements in quality of life, mood, and energy within six months of hGH therapy.

• Therapies lasting more than six months may lead to an increase in bone formation and density.

What Are The Benefits of hGH Therapy For Women?

HGH therapy may offer numerous advantages for women, including:

• Boosted libido
• Stimulated hair growth
• Increased bone density
• Enhanced quality of life
• Better cholesterol levels
• Reduction of abdominal and visceral fat
• Enhanced skin healing and regeneration
• Improved mood with fewer depressive symptoms

HGH therapy may have significant benefits for women, particularly during menopause.

Based on studies spanning up to two years, extended hGH therapy could significantly lower the risk of osteoporosis.

Without intervention, bone loss may not show symptoms initially but could lead to sudden fractures or spinal collapses over time. In such scenarios, a combined treatment of hGH and estrogen replacement therapy may be necessary.

Moreover, the combination of Growth Hormone Deficiency (GHD) and menopause can cause symptoms like hot flashes, night sweats, and restlessness, which may disrupt sleep and overall well-being.

Research indicates that hGH therapy may alleviate these sleep disturbances by potentially stabilizing the activity of the hypothalamus.

What Are The Benefits of hGH Therapy For Men?

Research indicates that hGH therapy can offer several advantages for men, including:

• Increased energy
• Better lipid profiles
• Decreased belly fat
• Greater muscle mass
• Improved bone density
• Enhanced sexual desire
• Enhanced mood and overall life satisfaction

Furthermore, hGH therapy may enhance erectile function, based on experimental studies with human tissues. Setting realistic expectations is crucial when considering hGH therapy to avoid potential disappointment.

The positive outcomes from hGH treatment typically develop over time. Initial improvements may become noticeable after a month, and it could take up to six months to experience the full spectrum of benefits.

Risks of hGH Therapy for Men and Women

hGH injections are usually given subcutaneously and carry a minimal risk of localized side effects. Additionally, hGH can lead to more significant side effects at higher doses, including:

• Symptoms of water retention such as headaches, swelling (edemas), and joint pain
• Insulin resistance
• Acromegaly

Water retention, a frequent complication of hGH therapy particularly at elevated dosages, typically results in swelling in the hands and feet and can cause discomfort in the joints and muscles.

Carpal tunnel syndrome may develop in some individuals due to swelling of the tissues around the wrist, which compresses and entraps the nerve within the carpal tunnel. This condition presents as pain, numbness, tingling, and weakness in several fingers, including the thumb. These symptoms generally resolve upon reducing the dosage.

Headaches, often due to increased cerebrospinal fluid and heightened intracranial pressure, are another common side effect of excessive hGH dosage. This is a temporary issue that usually subsides within a few weeks or with a dosage adjustment.

hGH treatment has been known to decrease insulin sensitivity, yet studies indicate that these effects are reversible, with metabolic parameters normalizing after three months of hGH.

Large-scale studies have also shown no significant increase in the incidence of type 2 diabetes among individuals undergoing legal hGH therapy. Similarly, extensive clinical trials have not found an increased risk of cancer associated with hGH.

However, if adverse reactions occur, it is crucial to consult a physician before altering the dosage. A doctor can guide the appropriate adjustments to hGH treatment to mitigate side effects while effectively managing Growth Hormone Deficiency (GHD) symptoms.

The use of illicit hGH for anti-aging and rejuvenation poses additional dangers. hGH products obtained without a prescription are often counterfeit, containing unknown ingredients that can cause unexpected side effects and health issues, including allergic reactions to undisclosed components.

Do hGH Boosters and Alternatives Have the Same Effect?

The FDA has approved only hGH injections for hormone therapy, recognizing them as the only effective means of administering growth hormones.

This limitation is due to the peptide structure of hGH that is rapidly neutralized by the digestive system and cannot be effectively absorbed through the skin or mucous membranes.

Consequently, hGH injections are the only verified method that effectively delivers the hormone into the body. Such hGH products are legally available only with a prescription.

In contrast, many non-prescription hGH products are sold as homeopathic or herbal supplements. Some of these are marketed as natural hGH boosters, which contain various dietary and herbal ingredients.

Yet, they lack solid scientific support to back up their effectiveness. Moreover, if you have GHD you cannot benefit from such products as your pituitary gland does not function properly and no longer responds to stimuli.

Moreover, products marketed as hGH gels or pills without a prescription are not only ineffective but also fraudulent.

Such products could lead to adverse reactions due to other ingredients like inactive compounds, fillers, preservatives, or herbal extracts. These components can cause side effects that are not related to hGH and are often unpredictable.
