GHK-CU

Endogenous tripeptide that binds Cu²⁺ with high affinity. Activates fibroblasts via the TGF-β pathway and upregulates synthesis of collagen types I and III. Research demonstrates modulation of matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs), relevant to connective tissue homeostasis.

Naturally occurring tripeptide-copper complex originally identified in human plasma. Endogenous levels gradually decrease with age, making it a molecule of interest in research involving cellular repair pathways, metalloprotein interactions, and gene-expression regulation. Functions as a high-affinity copper-binding peptide, facilitating copper transfer among proteins and influencing enzymatic and oxidative-stress pathways in experimental systems. In laboratory settings, GHK-Cu has been shown to interact with genomic regulatory networks, influencing gene-expression patterns associated with cellular signaling, extracellular-matrix activity, and tissue-specific responses.
