GHK-Cu

Copper Peptide | Skin Regeneration & Anti-Aging Compound

GHK-Cu is a naturally occurring copper tripeptide found in human plasma, saliva, and urine. Plasma levels decline from ~200 ng/ml at age 20 to ~80 ng/ml by age 60. Research shows it affects 31.2% of human genes and promotes wound healing, collagen synthesis, and anti-aging effects. Note: Injectable GHK-Cu is not FDA-approved; most clinical evidence comes from topical studies and animal models.

Key benefits

Enhanced collagen production, accelerated wound healing, improved skin elasticity, reduced inflammation, hair growth stimulation, and antioxidant protection

How it works

GHK-Cu binds copper ions and activates multiple cellular pathways. Stimulates collagen synthesis, angiogenesis, immune modulation, and tissue remodeling genes for comprehensive anti-aging effects

Research indications

skin Regeneration

Collagen Synthesis — Increases type I and III collagen production for improved skin firmness and reduced wrinkle depth

Wound Healing — Accelerates closure of acute wounds and chronic ulcers with enhanced cellular migration and proliferation

Anti-Aging Effects — Reduces fine lines and age spots while improving overall skin texture and elasticity

hair Growth

Follicle Stimulation — Promotes hair follicle enlargement and extends the anagen (growth) phase for thicker hair

Scalp Health — Improves circulation and reduces scalp inflammation for optimal hair growth conditions

Hair Thickness — Increases hair shaft diameter and overall density over 12-16 weeks of consistent use

anti Inflammatory

Immune Modulation — Regulates inflammatory cytokine production and promotes balanced immune responses

Tissue Protection — Protects tissues from oxidative stress and inflammatory damage through antioxidant mechanisms

Healing Enhancement — Reduces excessive inflammation while maintaining beneficial inflammatory responses for healing

Administration

topical

injectable

Interactions

Synergistic

BPC-157 — Enhanced wound healing and tissue repair when used together

Synergistic

TB-500 — Different healing pathways that work well in combination

Use Caution

Melanotan II — Both affect melanin production, monitor for skin discoloration

Avoid combination

Copper Supplements — Risk of copper toxicity when combined with additional copper sources

Compatible

CJC-1295 — Growth hormone effects may complement collagen synthesis

Monitor Combination

Iron Chelators — May interfere with copper binding and peptide effectiveness

Safety notes

Monitor injection sites for unusual blue discoloration

Start with lower doses to assess copper tolerance

Use sterile injection technique to prevent infection

Watch for signs of copper toxicity (nausea, metallic taste)

Avoid excessive copper supplementation from other sources
