GHK-Cu 100mg Copper Peptide Research Compound

GHK-Cu 100mg is a high-capacity lyophilized presentation of glycyl-L-histidyl-L-lysine, the copper-binding tripeptide whose coordination behavior has made it a standing reference compound in peptide-metal chemistry. The compound is identical to the 50mg listing; what differs is the scale of work the vial is intended to support.

Sized for continuity across a study

The argument for the larger vial is lot continuity. A research program running parallel arms, or one collecting data over an extended period, introduces avoidable variability every time it switches to a fresh batch. Drawing an entire study from one 100mg lot removes batch-to-batch variation as a confounding factor — which matters disproportionately in metal-peptide work, where trace differences in copper stoichiometry can shift analytical results.

The larger format also reduces total handling events. Each opening of a lyophilized vial is an opportunity for moisture ingress, so consolidating a project into fewer containers is a practical stability advantage as well as an economic one. Cost per milligram is lower than the 50mg presentation.

Research context

Typical investigational areas include copper coordination and exchange studies, extracellular matrix protein models, comparative analysis against other short metal-binding sequences, and gene-expression profiling in cultured systems. Laboratories still establishing protocols usually start with the 50mg vial and move to this size once methods are settled.

Specifications

• Compound: GHK-Cu (glycyl-L-histidyl-L-lysine, copper complex)
• Label strength: 100mg
• Format: Lyophilized powder, high-capacity vial
• Best suited to: Extended studies and parallel experimental arms
• Intended use: Laboratory research only

Storage and handling

Keep sealed, cool, dry and out of direct light. Copper-peptide preparations are sensitive to moisture and light, and the larger vial format makes disciplined resealing between handling events more important, not less. Record the lot identifier — the single-lot advantage only holds if the lot is documented.
