The term "gH" typically refers to "growth hormone," a peptide hormone produced by the pituitary gland. It plays a crucial role in growth, metabolism, and body composition. Growth hormone stimulates growth in tissues and bones, making it essential during childhood and adolescence. In adults, gH helps maintain muscle mass, supports fat metabolism, and contributes to overall health. It is sometimes used in medical treatments for growth disorders and other conditions. However, misuse of growth hormone for athletic performance or anti-aging purposes can lead to serious health risks.
