Why independent testing?
We dont test in-house. Every batch goes to a third-party accredited laboratory that has no commercial interest in the result. The certificate you see here is exactly what we received - unedited. If a batch doesnt pass, it doesnt ship.
Research Overview

Built for multi-pathway research.

White Lyophilized Powder
Multi-pathway profile — commonly used as a reference point against single- and dual-pathway compounds in comparative protocols.
Batch-matched COA — every vial traces back to a specific lot's independent test results.
Available across three strengths — 5mg, 10mg, and 15mg, so protocols can scale without switching suppliers.

The Four Compounds in the Klow Blend

GHK-Cu

A copper-binding tripeptide studied in cell culture for extracellular matrix remodelling and antioxidant gene expression. It is sold on its own as GHK Cu 50mg.

BPC-157

A synthetic 15-amino-acid peptide examined in laboratory and animal-model work for angiogenesis signalling and fibroblast migration. Researchers who prefer a single compound can buy BPC 157 as a 10mg vial.

TB-500

A synthetic peptide based on thymosin beta-4, an actin-binding protein associated in the literature with cell migration and tissue remodelling. Researchers who prefer a single compound can buy TB 500 as a 10mg vial.

KPV

A tripeptide of lysine, proline, and valine that matches the C-terminal end of alpha-MSH. In vitro and preclinical studies have examined it in inflammatory signalling and cytokine pathways. It is listed alone as KPV 10mg.

Klow Blend vs Glow Blend

  • Compounds: Klow Blend: GHK-Cu, BPC-157, TB-500, KPV. Glow Blend: GHK-Cu, BPC-157, TB-500.
  • Number of compounds: Klow Blend: Four. Glow Blend: Three.
  • Vial format: Klow Blend: 80mg total. Glow Blend: 50/10/10mg.
  • Price: Klow Blend: $79.99. Glow Blend: $79.99.
  • Purity on current batch: Klow Blend: 99.38% (NLKLOW80501). Glow Blend: 99.91% (400001).

The Glow Blend suits studies that do not need KPV. The Klow adds a fourth compound for panels that do. Both ship with a lot-specific certificate.

Batch NLKLOW80501 Certificate

The certificate for the lot now shipping reports 99.38% purity by HPLC, tested July 3, 2026 by Freedom Diagnostics. Identity, purity, sterility, and endotoxin results are listed as passed. Each order is matched to a verified batch before packing, and you can confirm the lot with the batch lookup or the QR code on the vial.

Other Related Formats

Researchers who work mainly with the repair-research pair can choose the Wolverine peptide stack, which combines BPC-157 and TB-500 as a pre-built research stack. Like every lyophilized product in the catalogue, the Klow needs a diluent, and a 10ml vial of bacteriostatic water for peptides can be added to the same order.
