GHK-Cu

What is GHK-Cu?

GHK-Cu is a naturally occurring copper complex that was first identified in human plasma. It has powerful regenerative properties, particularly for skin and hair health.

Mechanism of Action

GHK-Cu acts as a feedback signal for tissue injury. It stimulates the synthesis of collagen and elastin, promotes blood vessel growth, and has potent antioxidant and anti-inflammatory effects.

Benefits

  • Tightens loose skin and reverses thinning
  • Repairs protective skin barrier proteins
  • Improves skin firmness, elasticity, and clarity
  • Reduces fine lines and depth of wrinkles
  • Promotes hair growth

Typical Dosage

  • 1-2mg per injection
  • 5 days/week or 3×/week protocols

Side Effects

  • Injection site pain (if not diluted properly)
  • Zinc depletion (supplement zinc if using long term)

Dosage Protocol

GHK-Cu is administered via subcutaneous injection using one of two common frequency patterns: (1) Conservative approach — 5 days per week (e.g., Monday-Friday), or (2) Alternative approach — 3 times per week (e.g., Monday, Wednesday, Friday). The typical dose range is 1–2 mg per injection. Gradual titration is recommended, starting at 1 mg and increasing to 2 mg as tolerated. Standard cycle length is 8–12 weeks, with possible extension based on individual response. The peptide can be injected at any consistent time of day. Research shows GHK-Cu supports collagen synthesis, tissue repair, and gene expression related to regenerative processes.

Reconstitution

Add 3.0 mL sterile or bacteriostatic water to the 100 mg vial to achieve approximately 33.3 mg/mL concentration. Draw water slowly and inject down the vial wall to minimize foaming. Gently swirl or roll the vial until fully dissolved—do not shake vigorously. Label with reconstitution date and refrigerate at 2–8°C, protected from light.

Dosing Schedule

Standard Protocol

  • •Weeks 1-2: 1 mg, 5× per week (≈3 units)
  • •Weeks 3-8: 1.5 mg, 5× per week (≈5 units)
  • •Weeks 9-12: 2 mg, 5× per week (≈6 units)
  • •Cycle length: 8-12 weeks

Advanced / Titration

  • •Alternative 3×/week protocol: 2 mg, 3× per week (Mon/Wed/Fri)
  • •Weeks 1-12: Consistent 2 mg dosing
  • •Lower total weekly dose, convenient schedule

Negative Interactions

  • Copper supplementation (may cause excess copper)
  • Heavy metal chelators
  • High-dose zinc (competes with copper)
