Overview

GH Fragment 176-191, also known as HGH Frag 176-191 or Somatotropin (176-191), is a synthetic peptide consisting of the last 16 amino acids of the 191-amino-acid human growth hormone (hGH) chain. Its sequence corresponds to positions 176 through 191 of the full hGH protein. The fragment has the molecular formula C78H123N23O22S2 and a molecular weight of approximately 1817.12 g/mol. Like the parent molecule, it contains a disulfide bond formed between two cysteine residues in the chain.

This fragment was first isolated and studied in the 1980s and 1990s by researchers investigating which portions of the growth hormone molecule were associated with different structural domains. It represents less than 10% of the full hGH protein by length. GH Fragment 176-191 is supplied as a white lyophilized powder that is soluble in water and remains stable under proper refrigerated storage conditions.

This product is strictly for research purposes only. Not approved for human or animal use.
