Component purity

Each peptide in the KLOW blend was assayed individually for chromatographic purity and quantified for its share of the total UV signal.

Component Purity (PPI) Composition (UV) Retention time
GHK-Cu 99.3% 55.7% 2.443 min
KPV 98.7% 13.7% 3.349 min
TB500 99.1% 13.5% 5.451 min
BPC-157 99.5% 17.1% 13.600 min

How to read this table. Purity (PPI) is the spectral homogeneity of each individual peak. Composition (UV) is each peak's share of the total UV signal — not a mass or molar ratio. Peptides with strong chromophores (e.g. copper chelates such as GHK-Cu) absorb UV disproportionately at the detection wavelength, so their UV share can exceed their true mass fraction. The full annotated chromatogram is on PeptideVerify.

What this verifies

  • Identity of each component peptide via mass spectrometry
  • Chromatographic purity per component by RP-HPLC
  • Sample as received from this manufactured lot, with chain of custody to the vial label
  • Independent third-party analysis — not self-reported by the manufacturer
