Klow Blend – 50/10/10/10mg
50/10/10/10mg, lyophilized — must be reconstituted. Klow combines four individually documented research peptides — GHK-Cu, BPC-157, TB-500, and KPV — each studied in its own body of published research for interaction with tissue-repair and inflammatory-signaling pathways. Supplied at research-grade purity for laboratory use only.
$300.00
Klow Blend combines four individually documented research peptides — GHK-Cu, BPC-157, TB-500, and KPV — each studied in its own body of published literature for interaction with tissue-repair, cellular-signaling, and inflammatory-pathway research. Researchers combine peptides such as these to study multiple, overlapping pathways in parallel; the summary below describes each component’s own published research individually. No combined-formulation study of this specific blend is described or implied.
What is in Klow Blend?
GHK-Cu
GHK-Cu is a naturally occurring copper-binding tripeptide present in human plasma at concentrations reported to decline with age. Research, notably work associated with biochemist Loren Pickart, has examined GHK-Cu’s association with gene-expression changes linked to collagen and elastin synthesis, and its role in tissue-remodeling and wound-healing signaling in cell and animal models.
BPC-157
BPC-157 is a synthetic pentadecapeptide based on a sequence identified in human gastric juice. Preclinical research, concentrated in work from a research group at the University of Zagreb, has examined its association with gastrointestinal-lining protection and tendon, ligament, muscle, and skin-tissue repair measures in tested animal models.
TB-500 (Thymosin Beta-4)
TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring actin-binding peptide. Research has examined its association with cell-migration, angiogenesis, and reduced inflammatory-marker measures across a range of tested tissue-injury models.
KPV
KPV is a synthetic tripeptide corresponding to the C-terminal fragment of alpha-MSH, retaining anti-inflammatory activity researchers have associated with alpha-MSH independent of its pigmentation-related effects. Research has examined KPV’s association with NF-κB-pathway signaling and cytokine-expression measures, largely in gut-inflammation (colitis) research models.

Research Applications
Tissue-Repair & Dermal-Signaling Research (GHK-Cu, BPC-157, TB-500)
Each of these three peptides has been individually studied for interaction with tissue-remodeling and repair-related signaling pathways — gene-expression modulation for GHK-Cu, gastrointestinal and connective-tissue protection for BPC-157, and actin-mediated cell migration for TB-500 — in tested cell and animal models relevant to skin- and wound-related research.
Inflammatory-Pathway Research (KPV)
KPV’s association with NF-κB-pathway modulation and reduced inflammatory-cytokine expression has been studied predominantly in gut-inflammation animal models, representing a distinct research area from the tissue-structural research associated with the blend’s other components.
