GHK-CU (1 Vial)

Buy GHK-Cu peptide — one of the most extensively researched regenerative copper tripeptide complexes available for laboratory investigation. GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring tripeptide first isolated from human blood plasma in 1973. At PSPeptides, every vial is independently tested at 99%+ purity via HPLC and mass spectrometry, US manufactured, and ships with a batch-specific Certificate of Analysis.

What Is GHK-Cu?

GHK-Cu is a tripeptide-copper(II) complex with the molecular formula C₁₄H₂₃N₅O₄·Cu and molecular weight of 403.93 Da (CAS: 49557-75-7). It exists naturally in human plasma, saliva, and urine — with plasma concentrations averaging ~200 ng/mL at age 20 but declining to ~80 ng/mL by age 60. This age-related decline correlates with decreasing tissue regenerative capacity. To learn more about how GHK-Cu works at the molecular level, see our complete GHK-Cu research guide.

Key Research Applications of Buy GHK-Cu Peptide

• Skin Regeneration & Collagen Stimulation: Research shows GHK-Cu can stimulate Type I and Type III collagen synthesis by up to 70% in laboratory models.
• Wound Healing: Demonstrated acceleration of wound closure through angiogenesis stimulation, fibroblast proliferation, and metalloproteinase modulation.
• Hair Follicle Research: GHK-Cu supports follicular cell proliferation and vascular endothelial growth factor (VEGF) production in hair follicle models.
• Gene Expression Modulation: The Broad Institute’s Connectivity Map identified GHK-Cu as influencing expression of approximately 4,000 human genes (~6% of the genome).
• Anti-Inflammatory Activity: Reduces TNF-alpha-induced IL-6 secretion in human dermal fibroblasts, with proposed anti-inflammatory benefits.
• Antioxidant Defense: Elevates superoxide dismutase (SOD) and other antioxidant enzyme expression in dermal tissue models.
