HGH – Human Growth Hormone

Human growth hormone, or human_growth_hormone, is a vital substance produced by the anterior pituitary gland, crucial for normal growth and development. This hormone, often called GH, peaks in levels during late adolescence but starts to decline in the second decade of life. For over 40 years, growth_hormone has been used to treat specific medical conditions. Recently, however, its popularity has surged among middle-aged individuals seeking anti-aging effects, teenagers aspiring to enhance their physique, and athletes aiming for improved performance. Athletic_performance_enhancement has led to GH being widely abused, ranking among the top three most commonly misused substances in sports.

Understanding Human Growth Hormone

Human growth hormone, abbreviated as HGH 또는 hGh, plays a critical role in stimulating cellular production, growth, and metabolic functions in the body. Secreted by the anterior pituitary gland, GH collaborates with other hormones to ensure proper growth and development. Naturally, GH levels peak at puberty before declining significantly past age 40. Growth hormone is readily available at health food stores, spas, and through various alternative medicine practitioners under different brand names like Genotropin®, Humatrope®, Norditropin®, Nutropin®, Saizen®, and Serostim®.

Pharmacology of Growth Hormone

The majority of synthetic growth hormone is produced using recombinant DNA technology, specifically the forms somatropin and somatrem. These synthetic hormones exhibit similar pharmacological properties to naturally occurring GH. Once injected, they are indistinguishable from the body’s natural hormone, activating GH receptors across various tissues to elicit numerous cellular responses, including metabolism regulation and muscle mass increase. GH levels typically rise during exercise, sleep, and stress.

Conditions Affecting GH Levels

Medical conditions can arise with abnormal GH levels, both low and high. Excessive GH can result in acromegaly, characterized by enlarged extremities and serious health issues, or pituitary gigantism leading to abnormal height increases. Conversely, GH deficiency may contribute to various short stature conditions, severely impacting health.

FDA-Approved Uses of Growth Hormone

The FDA has authorized several injectable HGH formulations, which require a prescription from a licensed physician. Initially approved in 1985 for treating short stature due to GH deficiency (GHD), GH has since received further approvals for conditions such as Prader-Willi syndrome, chronic renal insufficiency-related short stature, Turner syndrome, and intrauterine growth retardation. Recent approvals for GH use also address growth hormone deficiency in adults with pituitary tumors and AIDS-related wasting syndrome. Clinical evidence indicates that GH administration can yield numerous benefits, including:

• Increased muscle mass and bone density
• Reduced body fat
• Enhanced cognitive function
• Improved athletic performance
• Elevated cardiovascular response to stress and exercise

Dosage Information

Growth hormone is always administered via injection (subcutaneous or intramuscular) as oral consumption is ineffective. The rapid action of GH after absorption necessitates careful dosage consideration, which typically ranges from 0.01-0.1 mg/kg body weight for adults, depending on product type and intended use. Available formulations include both powder and liquid, with the former converted to solution prior to administration.

Growth Hormone Side Effects

Use of GH may bring several side effects, including:

• Generalized edema
• Carpal tunnel syndrome
• Joint and muscle discomfort
• Neuropathies (numbness and tingling)
• Elevated blood glucose levels

Prescription Requirements for GH

Legally, GH can be prescribed only for FDA-approved conditions, with many off-label uses—like in the realm of competitive sports and anti-aging—carrying risks that often outweigh potential benefits. Patients should be aware of the serious side effects associated with unregulated usage.

Potential Risks of Growth Hormone Therapy

Overconsumption of GH poses risks of overdose, potentially resulting in grave conditions like acromegaly. The hormone’s capacity to stimulate cell growth raises concerns about activating undesirable cell proliferation, potentially increasing cancer risks. Furthermore, side effects can include fluid retention and type 2 diabetes, emphasizing the necessity for informed decision-making regarding GH therapy.

Off-Label Uses of Growth Hormone

보디빌딩The prevalent off-label use of GH spans anti-aging and muscle building. GH abuse is rampant among athletes, who often combine it with other substances. Its appealing qualities often make it hard to detect, complicating regulatory efforts. Individual usage statistics remain uncertain; however, athletes sometimes admit to GH misuse. Monthly costs for bodybuilding can range from $500 to $2000, with a risk of purchasing counterfeit products.

Anti-Aging Applications

In pursuit of youthful vitality, many individuals resort to GH, hoping to diminish facial lines and wrinkles. Despite its popularity, GH lacks FDA approval for anti-aging treatment and shows no verifiable effects on skin texture or wrinkle reduction. The thriving anti-aging_market around unproven oral alternatives generates an estimated $70 million in revenue.

Sourcing Growth Hormone

The illicit market remains the primary source of HGH for most users, with instances of theft from pharmacies and unethical physicians prescribing it for unauthorized uses. Additionally, smuggling from regions like Mexico and Europe, along with unregulated online pharmacies, presents further challenges. Legally, GH is delivered exclusively via injection, despite marketing of ineffective delivery methods such as sprays or gels.

Challenges in Detection

Detecting synthetic GH in the body poses significant challenges; current methodologies can only identify the hormone for up to 48 hours post-injection. This technical limitation is well-known among athletes.

Sermorelin: An Alternative

Sermorelin, a newer drug, is an analog of growth hormone-releasing hormone (GHRH) produced by the hypothalamus to stimulate GH release. While it avoids detection in urine and blood after a specific period, Sermorelin requires 3-4 weeks for observable effects and lacks the potency of direct GH supplementation.

Regulatory Considerations

The prevalence of HGH abuse has initiated federal regulations restricting its distribution. The 1990 Anabolic Steroids Control Act criminalizes possession or distribution of GH, incurring potential prison sentences and fines. In March 2007, a proposal aimed to classify HGH as a schedule III controlled substance, reflecting its status as a performance-enhancing drug, disallowing its use in competitive sports.
