Human growth hormone (HGH) is a natural hormone produced by the pituitary gland in the brain. It plays a crucial role in growth, cell repair, and metabolism. HGH helps stimulate growth in children and adolescents, and it also helps maintain healthy tissues and organs throughout life. In adults, HGH levels decline with age, which can affect energy levels, muscle mass, and overall health. Some people use synthetic HGH for medical conditions or to enhance athletic performance, but misuse can lead to serious health risks. Always consult a healthcare professional before considering HGH treatments.
