Sermorelin is a synthetic peptide consisting of 29 amino acids, structurally similar to the body’s natural growth hormone-releasing hormone (GHRH). It works by signaling the pituitary gland to promote the natural release of growth hormone. While it was originally developed for use in growth hormone deficiency, particularly in pediatric populations, it is now primarily used in research and wellness settings. Sermorelin remains an area of interest in exploring its role in endocrine support and age-related hormone dynamics.
