Research Comparison

GLOW Stack vs KLOW Stack

A side-by-side research comparison of GLOW Stack and KLOW Stack drawn from DRPSHP' peptide database records.

GLOW Stack

GLOW is a single preparation containing three separately studied peptides: GHK-Cu, TB-500 and BPC-157. GHK-Cu is the copper(II) complex of glycyl-histidyl-lysine, a tripeptide originally isolated from human plasma. TB-500 is the seven-residue synthetic fragment Ac-LKKTETQ, copied from the actin-binding region of thymosin beta-4. BPC-157 is a 15-residue synthetic peptide derived from a protein described in gastric juice. Each has its own literature, largely in cell culture and animals. No published study has tested the three together, and there is nothing on how stable they are, or how they behave, when mixed.

KLOW Stack

KLOW is a single preparation made of four separately studied peptides: the three in GLOW (GHK-Cu, TB-500 and BPC-157) with KPV added. KPV is the C-terminal tripeptide of alpha-melanocyte-stimulating hormone. The other three are, in turn, a copper-bound tripeptide first isolated from human plasma, the synthetic seven-residue thymosin beta-4 fragment Ac-LKKTETQ, and a 15-residue synthetic peptide derived from a sequence in a gastric juice protein. Cell culture and animal models make up nearly all of the work on each component. No published study has put the four together, and information about their chemical stability in a mixture is lacking, so the blend has no literature of its own.

Reading a comparison

A comparison places two records side by side; it does not merge them. Each description above is drawn from that compound's own record, and the two were not necessarily characterised by the same methods, at the same time, or to the same level of detail. Before comparing any attribute, it is worth establishing that both records describe the substance you think they describe — names are not identifiers, and two entries sharing a name can differ in salt form, stereochemistry or the convention used to state a mass. Where a figure carries no method beside it, the comparison is between two reported numbers rather than between two measurements.
