Important Notice
This product is intended for laboratory and research use only. Not for human or veterinary use. By purchasing, you confirm this product will be used exclusively for in-vitro research purposes.
Reconstitution Required
This peptide ships lyophilized (dry powder) and requires bacteriostatic water to reconstitute before use. BAC water is sold separately.
When This Product May Not Suit Your Research
- ⚠If your research requires GMP-grade material for clinical applications — research-grade peptides are not intended for clinical use.
- ⚠If your lab lacks proper cold storage (-20°C freezer) — this peptide's stability may be compromised at higher temperatures.
- ⚠If your study protocol requires FDA-approved reference standards — contact USP or a certified reference material provider.

About Klow Blend (BPC-157 + GHK-Cu + TB-500 + KPV) 80mg
Klow Blend is a four-peptide research formulation that extends the Glow Blend composition (BPC-157, GHK-Cu, TB-500) with KPV, an anti-inflammatory tripeptide derived from the C-terminal sequence of alpha-MSH. Total content is 80mg across the four components. The addition of KPV is the defining difference from the three-peptide blend.
KPV (Lys-Pro-Val) is the C-terminal tripeptide of alpha-melanocyte-stimulating hormone (alpha-MSH). Alpha-MSH's anti-inflammatory activity has been known for decades, and KPV was identified as the minimal active sequence responsible for this effect. KPV acts through melanocortin receptors (particularly MC1R) and has direct anti-inflammatory activity in intestinal epithelial cells, making it particularly interesting for GI inflammatory models. It downregulates NF-kB-dependent inflammatory pathways and reduces pro-inflammatory cytokine production. Unlike the full alpha-MSH molecule, KPV is a small, stable tripeptide with reasonable oral and local bioavailability.
The rationale for KPV's inclusion in a skin-focused blend is that inflammation is a significant driver of both acute skin conditions and chronic aging processes. Adding an anti-inflammatory peptide alongside the repair and remodeling signals provided by the other three compounds addresses an additional axis of skin and tissue biology.

What is KPV and why add it to the BPC-157/GHK-Cu/TB-500 blend?
KPV (Lys-Pro-Val) is the C-terminal tripeptide of alpha-MSH that retains the parent molecule's anti-inflammatory activity. It acts through melanocortin receptors and directly suppresses NF-kB-dependent inflammatory signaling in epithelial cells. Its addition to the blend adds an anti-inflammatory dimension to the tissue repair and remodeling effects of BPC-157, GHK-Cu, and TB-500. The rationale is that inflammation resolution and tissue repair often need to be addressed simultaneously -- KPV helps address the inflammatory side while the other peptides support the structural repair processes.
What is the difference between Klow Blend and Glow Blend?
Klow Blend adds KPV to the Glow Blend composition (BPC-157 + GHK-Cu + TB-500). KPV contributes anti-inflammatory activity through melanocortin receptor signaling, which is not part of the Glow Blend. The Klow Blend total dose is 80mg versus 70mg for Glow Blend. Researchers primarily interested in inflammatory processes alongside tissue repair would favor Klow Blend; those focused specifically on collagen synthesis, cell migration, and vascular effects without the added anti-inflammatory dimension might prefer the Glow Blend for a simpler composition.
Is KPV bioavailable via different routes?
KPV is a short tripeptide with better stability than larger peptides. It has documented biological activity in intestinal epithelial cell models when administered directly, and some research has explored nanoparticle formulations for oral delivery. In this injectable blend, it is delivered systemically along with the other components. The tripeptide's small size makes it more resistant to proteolytic degradation than larger peptides, though the full pharmacokinetic picture for this route of administration requires study-specific characterization.
Klow Blend is supplied for laboratory research use only. Not approved for human use. Handle in compliance with institutional biosafety guidelines.
