KLOW is a four-component peptide blend containing BPC-157, TB-500, GHK-Cu, and KPV. BPC-157 (10mg) is a pentadecapeptide — a chain of 15 amino acids — originally identified as a partial sequence of a protein found in human gastric juice. TB-500 (10mg) is a synthetic version of a 43-amino-acid segment of thymosin beta-4, a protein present in most animal cells. GHK-Cu (50mg) is a tripeptide — glycyl-L-histidyl-L-lysine — bound to a copper(II) ion, first isolated from human plasma in 1973 by Dr. Loren Pickart. KPV (10mg) is a tripeptide composed of lysine, proline, and valine, derived from the C-terminal end of alpha-melanocyte-stimulating hormone (alpha-MSH).

The blend totals 80mg of lyophilized peptide powder and appears white to off-white with a slight blue tint from the copper content of GHK-Cu. It is water-soluble and should be stored refrigerated at 2–8 °C. This product is strictly for research purposes only.
