Blend Composition
Product Overview
Aventris Labs supplies the KLOW Blend as a pre-mixed, four-component research formulation combining GHK-Cu, BPC-157, TB-500, and KPV in a single lyophilized amber vial. Each component is sourced from verified manufacturers and independently verified through the Aventris Batch Verification Report (BVR) system.
GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper complex, CAS 89030-95-5, 401.91 Da) is a naturally occurring tripeptide-copper complex — its characteristic blue colour is a marker of copper(II) complexation. BPC-157 is a synthetic 15-amino acid pentadecapeptide (C₆₂H₉₈N₁₆O₂₂, 1419.75 Da). TB-500 is a synthetic peptide fragment derived from the active region of Thymosin Beta-4 (C₃₈H₆₈O₁₄N₁₀, 889.01 Da). KPV is a synthetic C-terminal tripeptide of α-MSH (Lys-Pro-Val, C₁₆H₃₀N₄O₄, 342.43 Da).
By supplying all four components pre-mixed in a single amber vial, Aventris eliminates the need for researchers to source, verify, and combine individual components — streamlining multi-peptide analytical workflows.

Frequently Asked Questions
About the Blend
Is the blend pre-mixed or a multi-vial kit?
Pre-mixed. All four components are combined into a single lyophilized amber vial. One vial contains 50mg GHK-Cu, 10mg BPC-157, 10mg TB-500, and 10mg KPV.
What is the difference between KLOW and GLOW?
GLOW is a three-component blend (BPC-157 + TB-500 + GHK-Cu, 70mg total). KLOW adds a fourth component — KPV (Lys-Pro-Val tripeptide, 10mg) — bringing the total to 80mg. KPV is a C-terminal tripeptide fragment of α-MSH, structurally distinct from the other three components.
Why is the KLOW Blend in an amber vial?
GHK-Cu is a copper peptide complex sensitive to photodegradation. Amber glass provides protection from UV and visible light, preserving GHK-Cu integrity throughout storage and handling.
Why does my vial look nearly empty?
The GHK-Cu (50mg) will be the most visible due to its blue colour and larger mass. The remaining 30mg — BPC-157, TB-500, KPV — are white lyophilized powders that may appear as a thin film at these masses. There are no fillers. Learn more →
Quality & Verification
How are components verified if it’s a blend?
