The KLOW Peptide Blend is a comprehensive four-component research stack designed for high-level interrogation of tissue remodeling and immune-signaling pathways. Building upon the GLOW foundation, this blend integrates the potent anti-inflammatory tripeptide KPV to expand its utility into epithelial-barrier and immune biology research.

Peptide Classification and Description

The KLOW stack is a specialized quad-peptide research blend that synthesizes the properties of four distinct signaling molecules:

GHK-Cu (Copper Tripeptide-1): A copper-binding peptide that serves as a primary signal for extracellular matrix remodeling and dermal repair.
TB-500 (Thymosin-β4 fragment): A regenerative peptide focused on cell migration and structural organization of the extracellular matrix.
BPC-157 (Body Protection Compound-157): A gastric-derived peptide known for its potent angiogenic and cytoprotective properties.
KPV (Lys-Pro-Val): A tripeptide derived from alpha-melanocyte-stimulating hormone ($\alpha$-MSH) that targets inflammatory signaling and epithelial-barrier integrity.

Targets, Effects, and Explored Roles

Category	KLOW Research Details
Primary Targets	Fibroblasts, endothelial cells, keratinocytes, and inflammatory cytokines.

Core Mechanism and Function

Component	Mechanism of Action	Key Biological Function
GHK-Cu	Modulates gene expression for collagen synthesis and antioxidant enzymes.	Facilitates dermal remodeling and tissue structural integrity.
TB-500	Regulates actin polymerization for cellular mobility.	Drives rapid cellular migration to sites of tissue damage.
BPC-157	Upregulates growth factor pathways and promotes vascular formation.	Supports angiogenesis and stabilizes localized repair environments.
KPV	Interacts with MC1 receptors to inhibit pro-inflammatory pathways like NF-$\kappa$B.	Provides advanced anti-inflammatory modulation and barrier protection.

Clinical Potential

While strictly for laboratory use, the components within the KLOW blend are critical subjects in regenerative medicine for:

Complex Tissue Repair: Studying the synergistic repair of multi-tissue injuries involving skin, muscle, and tendons.
Immune-Mediated Dermatology: Researching the management of hyper-inflammatory skin conditions and barrier dysfunction.
Advanced Angiogenesis: Exploring enhanced blood vessel formation in compromised tissue environments.
