GHK-Cu

GHK-Cu is a naturally occurring copper-binding tripeptide composed of glycine, histidine, and lysine. It is widely studied for its role in tissue remodeling, wound repair, and regulation of gene expression associated with cellular regeneration. In biological systems, GHK binds copper ions to form the bioactive complex GHK-Cu, which functions as a signaling molecule involved in maintaining tissue integrity.

Research interest in GHK-Cu focuses on its ability to influence extracellular matrix remodeling, stimulate collagen synthesis, modulate inflammatory signaling, and support cellular renewal processes. Due to its broad biological activity, GHK-Cu is frequently investigated in regenerative biology, skin physiology, and age-related tissue degeneration models.

The peptide is supplied as a lyophilized powder to ensure optimal stability during storage and handling.

GHK-Cu activates a broad range of tissue remodeling pathways including TGF-β signaling, matrix metalloproteinase (MMP) modulation, and angiogenesis. Research has documented its ability to upregulate collagen synthesis, stimulate wound contraction, and promote nerve regeneration in preclinical models. At the genomic level, GHK-Cu has been shown to reset gene expression patterns associated with aging, activating protective and regenerative genes (Pickart & Margolina, 2018 — Biomolecules).

The peptide is supplied as a lyophilized powder to ensure optimal stability during storage and handling. Store at -20°C. See also: Glow(Blend), Snap-8 10mg, Glutathione 600 mg
