Sermorelin is a synthetic 29-amino acid peptide analog of the naturally occurring Growth Hormone-Releasing Hormone (GHRH). It represents the shortest fully functional fragment of GHRH, specifically the N-terminal 1-29 sequence. In research settings, it is primarily studied for its ability to stimulate the pituitary gland to produce and secrete growth hormone (GH) in a pulsatile manner, making it a critical tool for investigating endocrine feedback loops and somatotropic axis regulation.
