GH Fragment 176-191
Price range: $76.00 through $95.00
KLOW is a four-peptide research blend totaling 80mg of lyophilized powder. It contains BPC-157 (10mg), a 15-amino-acid synthetic peptide derived from a sequence found in human gastric juice protein; TB-500 (10mg), a 43-amino-acid fragment of the naturally occurring protein thymosin beta-4; GHK-Cu (50mg), a copper-bound tripeptide first isolated from human blood plasma in 1973; and KPV (10mg), a three-amino-acid fragment from the C-terminal region of alpha-melanocyte-stimulating hormone. The powder appears white to off-white with a faint blue tint from the copper in GHK-Cu. It dissolves readily in water and should be stored refrigerated at 2–8 °C. Each component is a well-characterized peptide with an established chemical identity and published molecular structure.

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.
