Human growth hormone (HGH) is a peptide hormone that is produced by the pituitary gland. It is responsible for growth and development in children and adolescents, and it also plays a role in metabolism, body composition, and immune function in adults.
HGH levels decline with age, and this decline is associated with a number of age-related changes, including decreased muscle mass, increased body fat, and impaired immune function. Boosting HGH levels can help to reverse these changes and improve overall health and well-being.
