Sermorelin, also known as GRF 1-29, is a synthetic peptide that functions by stimulating the pituitary gland to release growth hormone. Interest in Sermorelin started around the late 20th century when researchers explored its potential to mimic the natural growth hormone-releasing hormone (GHRH). Unlike the full GHRH, Sermorelin's shorter structure, consisting of 29 amino acids, allows it to retain biological activity while being more stable. Researchers are also looking at its role in various endocrine disorders. Today, it is primarily studied for its effects on:
- Growth hormone deficiency
- Aging-related research
- Muscle wasting conditions
- Endocrine system disorders
