Buy GHK-Cu – Copper-Binding Tripeptide
A sourcing reference for GHK-Cu, a research-grade copper-binding tripeptide used in laboratory study of dermal collagen synthesis and antioxidant pathway activity.
What Is GHK-Cu?
GHK-Cu is a copper-binding tripeptide consisting of the amino acid sequence Gly-His-Lys coordinated with a copper(II) ion. It is used in laboratory research focused on dermal collagen synthesis, wound-healing signaling, and antioxidant pathway activity in cellular models.
Why Researchers Use GHK-Cu
- Collagen synthesis pathways — laboratory characterization of fibroblast activity and extracellular matrix protein expression.
- Wound-healing signaling — investigation of growth factor expression and tissue-repair pathways in cellular models.
- Antioxidant pathway activity — evaluation of oxidative stress response markers under copper-tripeptide exposure.
- Comparative work — benchmarking against BPC-157 and other repair-focused research compounds.
How to Evaluate Purity and COA
- HPLC purity ≥98%.
- Mass spectrometry confirming the copper-bound tripeptide identity.
