Klow Blend Capsules

Oral capsule blend of GHK-Cu, BPC-157, TB-500, and KPV. Each peptide is separately studied in cellular and tissue-related research models. Supplied at research-grade purity for laboratory use only.

$250.00

Klow Blend Capsules combine four independently characterized research peptides — GHK-Cu, BPC-157, TB-500, and KPV — each studied in different but related areas of cellular and tissue research. Each component is described individually below; no dedicated published research characterizes the four-peptide combination as a single, unified compound.

GHK-Cu (Copper Peptide)

GHK-Cu is a naturally occurring copper-binding tripeptide first identified in human plasma. It has been studied extensively in dermal-research models for its relationship to collagen and elastin production pathways and wound-healing marker expression in tested skin models.

CAS Number 89030-95-5
Molecular Formula C14H22CuN6O4
Molecular Weight 340.91 g/mol

BPC-157

BPC-157 is a synthetic peptide derived from a partial sequence identified in gastric-juice protein research. A substantial body of animal-model research has examined its association with tissue-repair, gastrointestinal-healing, and tendon/ligament-recovery pathways.

CAS Number 137525-51-0
Molecular Formula C62H98N16O22
Molecular Weight 1419.53 g/mol

TB-500 (Thymosin Beta-4 Fragment)

TB-500 is a synthetic peptide related to thymosin beta-4, a naturally occurring actin-regulating protein. Research has examined its association with cell-migration, angiogenesis, and tissue-repair pathways in animal models.

CAS Number 77591-33-4
Molecular Weight ~4963.4 g/mol (full-length thymosin beta-4)

A confidently verified molecular formula for this fragment is not included here to avoid inaccuracy; researchers can request full batch characterization data via the Certificate of Analysis.

KPV

KPV is a tripeptide (Lysine-Proline-Valine) corresponding to the C-terminal sequence of alpha-melanocyte-stimulating hormone (alpha-MSH). It has been studied in laboratory research for its association with inflammatory-signaling pathways in gut and skin-related models, independent of alpha-MSH’s pigmentation-related activity.

Why Researchers Combine These Peptides

Researchers combine these four peptides to study multiple, related tissue-signaling and inflammatory pathways in parallel within a single formulation, rather than because the four-peptide combination has been characterized as a distinct compound in its own right.
