01Product details
Overview
Sermorelin is a synthetic analog of the first 29 amino acids of human growth hormone-releasing hormone (GHRH), the shortest fully bioactive fragment of the molecule. It functions as a GHRH receptor agonist on pituitary somatotrophs.
Research Background
Sermorelin is widely used in research as a reference GHRH agonist in studies of pituitary function, growth hormone (GH) pulsatility, and the somatotropic axis. It has been examined in models of age-related GH decline, body composition, sleep architecture, and metabolic regulation.
Storage & Handling
Store lyophilized peptide at -20°C for long-term stability. Once reconstituted with bacteriostatic water, store at 2–8°C and use within recommended timeframes. Handle under sterile laboratory conditions and avoid repeated freeze-thaw cycles.
Disclaimer:
This product is for laboratory research use only. It is not intended for human or animal consumption or for use in any diagnostic, therapeutic, or clinical applications.
02Mechanism of action
Sermorelin binds the growth hormone-releasing hormone receptor (GHRHR) on pituitary somatotrophs, activating Gs-coupled cAMP signaling. This stimulates synthesis and pulsatile release of endogenous growth hormone while preserving the negative-feedback loop with somatostatin and IGF-1, distinguishing it from direct exogenous GH administration.
03Research applications
Sermorelin is studied in research on pituitary function, growth hormone secretion patterns, body composition, and aging biology. It is a frequent comparator for newer GHRH analogs such as CJC-1295 and Tesamorelin.
