GHK-Cu at a Glance

What Is GHK-Cu?

GHK-Cu (Glycyl-L-Histidyl-L-Lysine:Copper) is a naturally occurring copper peptide complex found in human plasma, saliva, and urine. Its concentration in the body declines significantly with age, and supplementation has been studied for its potential regenerative and anti-aging properties.

GHK-Cu has been shown to modulate the expression of over 4,000 genes, including upregulating collagen synthesis, promoting wound healing, stimulating blood vessel growth, reducing inflammation, and potentially promoting hair follicle regeneration. It is used both topically (in skincare products) and via subcutaneous injection for systemic anti-aging benefits.

How to Reconstitute GHK-Cu

GHK-Cu comes as a lyophilized (freeze-dried) powder that must be reconstituted with bacteriostatic water before use. The process is standard for all peptides:

• Wipe the tops of both vials (ghk-cu and BAC water) with alcohol prep pads
• Draw your chosen amount of BAC water (typically 2 mL) into an insulin syringe
• Insert the needle into the ghk-cu vial and let the water drip slowly down the inside wall
• Gently swirl the vial until the powder fully dissolves — never shake
• The solution should be clear and colorless; discard if cloudy or discolored

GHK-Cu Side Effects

Understanding potential side effects helps you use ghk-cu more safely. Most side effects are dose-dependent and may improve over time.

Common Side Effects

• Very well-tolerated at standard doses
• Mild injection site redness (temporary)
• Slight metallic taste (rare, related to copper)

Less Common Side Effects

• Mild nausea (uncommon)
• Temporary skin flushing
• Lightheadedness (rare)

How to Store GHK-Cu

Before reconstitution: Store lyophilized (powder) ghk-cu in a cool, dry place away from direct sunlight. Refrigeration is ideal for long-term storage of unreconstituted peptides.

After reconstitution: Store the reconstituted vial upright in a refrigerator at 36-46°F (2-8°C). Do not freeze. The solution typically remains stable for 4-6 weeks. Always swab the vial stopper with an alcohol pad before each use.

GHK-Cu for Skin, Hair & Healing

GHK-Cu is unique among peptides because it addresses multiple systems simultaneously. Here are the three main use cases:

• Anti-aging / Skin: Promotes collagen I and III synthesis, improves skin elasticity, reduces fine lines and hyperpigmentation. Both injectable and topical forms are effective for skin.
• Hair restoration: May increase hair follicle size and promote the anagen (growth) phase. Often combined with topical minoxidil. Results typically require 3-6 months.
• Wound/tissue healing: Accelerates healing of surgical wounds, scars, and tissue damage. The copper component is essential for proper collagen cross-linking and tissue remodeling.
