GHK-Cu
GHK-Cu is a naturally-occurring copper-binding tripeptide (Glycyl-L-Histidyl-L-Lysine bound to copper). It has been studied in published research since the 1970s and is one of the most-researched copper peptides in the scientific literature.
A naturally occurring copper-binding tripeptide (Glycyl-L-Histidyl-L-Lysine + copper), studied since the 1970s.
Primary research focus
- Skin research — wound healing, remodeling, anti-aging
- Hair-follicle signaling
- Gene-expression and anti-inflammatory studies
Mechanism of Action
Published research shows GHK-Cu delivers copper to tissue and modulates multiple signaling pathways in research models — including tissue remodeling, wound repair signaling, antioxidant response, and gene expression modulation. Gene expression research has shown GHK-Cu affects a wide range of transcription in skin cell cultures. The copper delivery aspect is central to the mechanism — bioavailable copper is required for many enzymes involved in tissue repair research.
Research Applications
- Skin research — the most-published area (wound healing, skin remodeling, anti-aging cosmetic research)
- Wound healing research — foundational literature base
- Hair follicle research — published work on follicle signaling
- Gene expression research — broad transcriptional effects in cell culture
- Anti-oxidant and anti-inflammatory research
Dosing Reference (Published Literature)
Research protocols reference both topical (the most-studied route in published cosmetic science literature) and systemic administration. Topical research concentrations are typically in the ppm range in published formulations. Systemic research dosing has referenced low microgram ranges subcutaneously.
Synergistic Compounds
- BPC-157 — Both studied for tissue repair through different mechanisms.
- TB-500 — Both contribute to tissue repair research via complementary pathways.
- Epithalon — Both are studied in anti-aging research contexts.
- Thymosin-Alpha-1 — Immune-aging research overlap.
