Research Peptide Blend
Klow is a four-peptide research blend of GHK-Cu, KPV, BPC-157, and TB-500. Each is studied separately in tissue-repair, skin, and anti-inflammatory research, and the blend is used in preclinical models that look at tissue repair and inflammation together. The molecular details for every component appear below.

A four-component formulation combining a copper-binding tripeptide (GHK-Cu), an alpha-MSH-derived tripeptide (KPV), a gastric-juice-derived pentadecapeptide (BPC-157) and a Thymosin Beta-4-related actin-binding peptide (TB-500). The components act through distinct mechanisms; the blend has no single target.
Research Focus
Used in tissue-repair, dermatological and regenerative research contexts; each component is studied separately.
Lyophilized
-20°C
protect from light; stable months desiccated.
Reconstituted
2-8°C
days to weeks; avoid freeze-thaw.
GHK-Cu component is sensitive to alkaline pH; blend ratios vary by supplier.
