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.
Published laboratory reports are available for selected lots. Check each report for its result and stated method. For research purposes only.

About Klow Blend (BPC-157 + GHK-Cu + TB-500 + KPV) 80mg
Klow Blend is a four-peptide research blend that extends the Glow Blend composition (BPC-157, GHK-Cu, TB-500) with KPV, a 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). The anti-inflammatory signaling of alpha-MSH has been studied for decades, and KPV was identified in experimental models as the minimal sequence that retains this activity. In cell and animal models, KPV acts through melanocortin receptors (particularly MC1R) and has been reported to reduce NF-kB-dependent signaling and pro-inflammatory cytokine production in intestinal epithelial cells, which is why it is used in GI inflammation research models.
Klow Blend lets researchers study KPV together with BPC-157, GHK-Cu, and TB-500 in one experimental system, and compare it with the three-peptide Glow Blend.

Storage
Store at -20°C before reconstitution. Refrigerate at 2-8°C after reconstitution and use within 28 days. Protect from light, particularly due to GHK-Cu photosensitivity.
What is KPV?
KPV (Lys-Pro-Val) is the C-terminal tripeptide of alpha-MSH. In cell and animal models, it has been reported to act through melanocortin receptors and to reduce NF-kB-dependent inflammatory signaling in epithelial cells. Klow Blend supplies it together with BPC-157, GHK-Cu, and TB-500, so researchers can study the four compounds in one system.
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 is studied in melanocortin receptor and inflammatory signaling research, and the Glow Blend does not contain it. The Klow Blend total peptide content is 80mg versus 70mg for Glow Blend. Researchers who want to include inflammatory signaling readouts may choose Klow Blend; those studying collagen synthesis, cell migration, or vascular signaling without KPV may prefer the simpler Glow Blend.
Klow Blend is supplied for laboratory research use only. Not approved for human use. Handle in compliance with institutional biosafety guidelines.
