KLOW vs GLOW: what's in each research blend

KLOW and GLOW are two multi-component lyophilized reference preparations. This guide compares exactly what each vial contains and how each lot is verified.

Composition at a glance

Both blends share a core of GHK-Cu, BPC 157 and TB-500. KLOW adds the KPV tripeptide.

  • KLOW (GVL-BLND-01), 80 mg: GHK-Cu 50 mg, KPV 10 mg, BPC 157 10 mg, TB-500 10 mg
  • GLOW (GVL-BLND-02), 70 mg: GHK-Cu 50 mg, BPC 157 10 mg, TB-500 10 mg

Why researchers use multi-component preparations

A single vial holding several characterized peptides keeps handling and storage conditions identical across components, which simplifies comparative screening and reduces variability between vials.

Choosing between KLOW and GLOW

The choice depends on study design. Study designs that include KPV as a variable call for KLOW; study designs focused on the GHK-Cu, BPC 157 and TB-500 combination alone call for GLOW. Neither blend is intended for human or veterinary use.

Storage

Both blends ship lyophilized and should be stored at -20 °C, protected from light. See our storage and handling guide for more detail.

How each blend lot is verified

Multi-component vials are harder to test than single peptides, so documentation matters even more. Every GoVida Labs lot is tested by an independent, third-party USA laboratory, and every COA includes an HPLC purity chromatogram and a mass spectrometry identity check. The lot number on each vial matches its COA, which you can review on the COA page before ordering.

The GoVida Labs testing standard

What the standard should be, and how we meet it

The standard every supplier should meet

  • A COA for every lot, not one generic report per product.
  • Purity measured by HPLC, with the chromatogram shown.
  • Identity confirmed by mass spectrometry.
  • A lot number on the vial that matches the COA exactly.
  • Realistic, honestly reported results.

What GoVida Labs does
