GHK-Cu + KPV Blend 50mg / 20mg

GHK-Cu 50 mg / KPV 20 mg is a high-purity dual-peptide research preparation containing 50 mg GHK-Cu and 20 mg KPV, supplied exclusively for scientific investigation and controlled laboratory experimentation. For research use only — not for human or veterinary use.  

Product Overview

GHK-Cu 50 mg / KPV 20 mg is a dual-peptide research preparation combining two distinct peptide compounds within a single lyophilized research vial. GHK-Cu is a copper-binding tripeptide widely investigated within peptide chemistry, molecular signalling and cellular research models, while KPV is a short tripeptide studied in experimental systems involving peptide-mediated signalling and biochemical regulatory pathways. This research preparation contains 50 mg GHK-Cu together with 20 mg KPV, providing researchers with a combined peptide material for controlled laboratory investigation. Independent third-party laboratory analysis confirmed greater than 99.8 percent purity for GHK-Cu and 99.3 percent purity for KPV. Identity was further evaluated through retention time analysis and mass spectrometry, with molecular ion masses identified at 341 Da for GHK-Cu and 342 Da for KPV. Microbiological testing reported 0 CFU/g for both total aerobic microbial count and total yeast and mold count, while bacterial endotoxin analysis returned a result of 0.005 EU/mg. Comprehensive elemental impurity screening additionally reported arsenic, cadmium, mercury, lead, nickel, vanadium and cobalt below 0.001 ppm. These independently generated analytical results provide detailed batch-specific documentation for this GHK-Cu 50 mg / KPV 20 mg research preparation.  

Peptide Overview

GHK-Cu and KPV are structurally distinct tripeptides investigated across different areas of experimental peptide and molecular research. GHK-Cu consists of the peptide sequence glycyl-L-histidyl-L-lysine associated with copper, creating a copper-binding peptide complex frequently examined within biochemical and cellular research systems. KPV is a short peptide consisting of the amino acid sequence lysine-proline-valine and is investigated within controlled laboratory models involving peptide signalling and molecular regulatory mechanisms. The combination of 50 mg GHK-Cu and 20 mg KPV allows researchers to investigate both peptide structures within the same controlled experimental preparation. Each peptide component was independently characterised by Liquilabs using peptide screening, retention time analysis and mass spectrometry.  

Historical Background and Scientific Context

Short-chain peptides and peptide-metal complexes have become increasingly important research materials within modern peptide chemistry, molecular biology and biochemical investigation. Advances in peptide synthesis and analytical instrumentation now allow individual peptide components within combined research preparations to be characterised independently. Chromatographic techniques can assess assay content and purity for individual compounds, while retention time analysis and mass spectrometry provide additional information regarding molecular identity. Microbiological analysis, bacterial endotoxin testing and elemental impurity screening further contribute to the analytical characterisation of lyophilized peptide research materials. GHK-Cu 50 mg / KPV 20 mg represents a dual-peptide preparation in which both peptide components have been independently characterised within the same production batch.
