Sermorelin

Overview

Sermorelin is a synthetic peptide consisting of the first 29 amino acids of human growth hormone-releasing hormone (GHRH), which in its full form contains 44 amino acids. Its molecular formula is C₁₄₉H₂₄₆N₄₄O₄₂S, with a molecular weight of 3,358.04 g/mol (CAS 86168-78-7). It was first synthesized in the 1980s and is sometimes referred to as GRF(1-29)NH₂, indicating that it corresponds to the first 29 residues of growth hormone-releasing factor with an amidated C-terminus.

The 29-amino-acid fragment represents the shortest sequence of GHRH that retains the complete receptor-binding sequence of GHRH. The single sulfur atom in its formula comes from a methionine residue at position 27. In its research-grade form, Sermorelin appears as a white to off-white lyophilized powder that dissolves readily in water and remains stable under refrigerated storage.
