Modified GRF (1-29) often abbreviated as mod GRF (1-29), originally known as tetrasubstituted GRF (1-29), is a term used to identify a 29 amino acid peptide analogue of growth-hormone-releasing hormone (GHRH), a releasing hormone of growth hormone (GH). It is a modified version of the shortest fully functional fragment of GHRH, often referred to as growth hormone releasing factor (1-29) (abbreviated as GRF (1-29)), and also known by its standardized name, sermorelin.
