Mechanism of Action
Gene Expression Modulation
GHK has been shown to alter the expression of over 4,000 human genes, with the majority promoting wound healing, anti-inflammatory, and tissue remodeling pathways. This broad gene-regulatory effect is independent of copper chelation.Collagen Synthesis Signal
GHK triggers collagen I and III synthesis in dermal fibroblasts through TGF-beta-1 activation and upregulation of ECM remodeling enzymes (MMPs + TIMPs in balanced ratio).Copper Chelation (GHK-Cu)
The His residue in GHK has high affinity for Cu²⁺. When copper is present, GHK forms GHK-Cu, which has additional wound-healing, angiogenic, and anti-inflammatory properties beyond GHK alone.Research Summary
Gene Array Studies
Pickart et al. demonstrated GHK's broad transcriptional impact, anti-cancer gene signatures, collagen pathway upregulation, and anti-inflammatory marker suppression across multiple cell lines.Wound Healing
Both GHK and GHK-Cu accelerate wound closure in animal models. GHK-Cu shows stronger effects; GHK alone provides a baseline peptide-mediated effect.Skin Aging
Topical GHK reduces fine lines and improves skin texture in small human studies, attributed to collagen synthesis stimulation and improved ECM organization.Calculate your GHK dose Vial strength, BAC water, exact syringe draw in IU. Free, no signup. Open Calc →
Research Protocols
Topical Use
Formulated at 1–5% concentration in serum or cream base. Apply to target area twice daily. Minimum 8-week assessment period for visible skin outcomes.Injectable Research
Less common than GHK-Cu for injectable use. When used, typically 1–2 mg subcutaneously into target tissue area.Storage & Handling
Store at 2–8°C. Protect from light. GHK is more stable than GHK-Cu as it lacks the reactive copper ion. Shelf life 1–2 years when properly stored.
