GHK-Cu Peptide 100mg Lab Grade Research Peptide — ≥99% Purity

GHK-Cu is a tripeptide-copper complex consisting of glycyl-L-histidyl-L-lysine (Gly-His-Lys) bound to a copper(II) ion. It is found naturally in human plasma, saliva, and urine. Plasma levels decline with age from about 200 ng/mL at age 20 to roughly 80 ng/mL by age 60.

The peptide has high affinity for copper(II) — the binding constant is approximately 10^16 M^-1. This tight binding is what makes the complex stable under normal storage conditions. The copper ion participates in redox reactions and is thought to facilitate peptide uptake into cells. The copper content specification is 14-16% by weight for a properly formed complex.

This vial contains 100 mg, which is a high quantity for a tripeptide. Researchers running large-scale cell culture experiments, multiple assay replicates, or long-term protocols may find this size more practical than standard 5 mg or 10 mg vials.

The lyophilized powder has a distinctive blue color due to the d^9 electronic configuration of Cu(II) in the peptide complex. This is normal and indicates proper copper coordination. Protect from light during storage to prevent photodegradation.
