GLOW vs KLOW
GLOW and KLOW are multi-peptide research blends built on the same three-peptide base. KLOW adds a fourth peptide, KPV. Here is exactly what is in each vial and why researchers choose one over the other.
Both blends are supplied as freeze-dried powder. Browse the full range of lyophilized research peptide vials.

- GLOW (70mg): GHK-Cu 50mg + BPC-157 10mg + TB-500 10mg
- KLOW (80mg): GHK-Cu 50mg + BPC-157 10mg + TB-500 10mg + KPV 10mg
- The only difference: KLOW includes 10mg of KPV. Everything else is identical.
What each component is studied for
GHK-Cu is a copper-binding tripeptide studied in fibroblast, collagen and wound-model research. See the full GHK-Cu guide.
BPC-157 is a 15-amino-acid peptide studied mainly in rodent tendon, ligament and gastrointestinal models. See the BPC-157 guide.
TB-500 is a synthetic peptide related to the active region of thymosin beta-4, a protein involved in actin regulation. It is studied in cell-migration and tissue-repair models.
KPV is a tripeptide (lysine-proline-valine) that corresponds to the C-terminal end of alpha-melanocyte-stimulating hormone (alpha-MSH). It is studied mainly for inflammatory signaling, including in experimental colitis and gut-epithelium models.
Which blend fits which study
- Choose GLOW when the focus is skin-matrix and tissue-repair models and you do not need an inflammatory-signaling variable.
- Choose KLOW when you want the same repair base plus KPV's inflammatory-signaling line of research in a single vial.
- Choose single peptides when you need to isolate one compound's effect. Blends make it impossible to attribute a result to one component.
