HGH

Human growth hormone, or HGH, is a 191-amino-acid peptide hormone studied for growth regulation, protein synthesis, lipid metabolism, tissue repair, and IGF-1 signaling. In research settings, HGH is a central reference compound for understanding the growth hormone axis and its downstream effects on bone, muscle, connective tissue, liver metabolism, and body composition. Because HGH acts broadly across multiple tissues, it is used to compare direct hormone exposure with upstream secretagogues such as GHRH analogs and GHRPs. Researchers study HGH to better understand endocrine regulation, metabolic adaptation, and anabolic signaling pathways.
