Sermorelin

Sermorelin is a synthetic analog of growth hormone releasing hormone, studied for its ability to stimulate pituitary growth hormone production through the GHRH receptor. It is often used in research focused on GH-axis signaling, endocrine rhythm, IGF-1 response, recovery markers, sleep biology, and age-related hormone changes. Because sermorelin works upstream at the pituitary rather than replacing growth hormone directly, it is useful for studying the body’s regulated hormone-release mechanisms. Researchers compare sermorelin with longer-acting compounds such as CJC-1295 to understand differences in half-life, pulse pattern, and endocrine response.
