KLOW is one 80 mg lyophilized vial holding 50 mg GHK-Cu and 10 mg each of BPC-157, TB-500 (Thymosin Beta-4, full-length) and KPV. GHK-Cu is its only copper carrier, for a theoretical copper content of 9.88 % of the declared peptide mass.

First page, low resolution, numbers and dates covered. Full, clear copy from sales.
Our catalogue's literature review found no published study of this four-peptide combination, so nothing is stated here about the blend as such.
The four peptides have each been studied alone: GHK-Cu in implanted wound chambers and on irradiated skin flaps in rats (Maquart 1993; Parker 2013); BPC-157 in rats after small-bowel resection (Sever 2009); thymosin beta-4 in mouse skin-wound models (Philp 2003); and KPV in intestinal cell lines and mouse colitis models, where it entered cells through the PepT1 transporter (Dalmasso 2008).

KLOW is the catalogue name of an 80 mg vial holding four peptides as one lyophilized powder: GHK-Cu, BPC-157, TB-500 (Thymosin Beta-4, full-length) and the tripeptide KPV (Lys-Pro-Val). The vial carries 50 mg of GHK-Cu and 10 mg of each of the other three, so the copper peptide is 62.5 % of the declared peptide mass. Ten vials make a kit, and you can order from one kit. KPV is the one peptide that sets KLOW apart from GLOW; it carries no copper, and neither do BPC-157 or TB-500. With 50 mg of the 1:1 GHK-Cu complex in 80 mg, the theoretical copper content is 9.88 % of the declared peptide mass, lower than in GLOW because the same copper is spread over one more peptide. Each batch has its own COA with HPLC purity, MS identity, bacterial endotoxin and fill, and our release specification assays each of the four peptides against its own label claim. The three copper blends are set side by side in copper blends compared.
50 mg GHK-Cu, 10 mg BPC-157, 10 mg TB-500 (Thymosin Beta-4, full-length) and 10 mg KPV in one 80 mg vial, a 50:10:10:10 split.
KLOW adds a fourth peptide, KPV, to the three in GLOW. Both carry 50 mg of GHK-Cu in their largest vial, so KLOW's copper share of the declared peptide mass is lower: 9.88 % against 11.29 % for GLOW 70 mg.
Both carry 50 mg of GHK-Cu, but KLOW spreads it over 80 mg with KPV added, against 70 mg for GLOW: 9.88 % against 11.29 % in theory.
