Sermorelin (GRF 1-29 NH2) is a 29 amino acid peptide that reproduces the first 29 residues of human growth hormone releasing hormone (GHRH), the shortest fragment that keeps full activity at the GHRH receptor. Preclinical work uses it as a reference GHRH receptor agonist in pituitary signaling studies and compares it with modified analogs such as CJC-1295.
Core Research Peptides supplies it as 5mg of lyophilized powder in a sealed vial under SKU CRP-SER-5, at 99% purity. It reconstitutes in bacteriostatic water and stores at -20°C for long term work, 2 to 8°C once reconstituted.
