GHK-Cu Protocol Guide
GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper Complex) is a naturally occurring copper-binding tripeptide researched for skin rejuvenation, wound healing, hair growth, collagen synthesis, and anti-aging. It works by binding copper(II) ions to activate tissue remodeling genes including collagen I/III, decorin, and glycosaminoglycans. This protocol covers injectable subcutaneous dosing at 1-2mg daily, topical application for skin and hair, reconstitution from a 100mg vial, and stacking with other anti-aging peptides.

Administration
Injectable Sites
- Systemic: Abdomen subcutaneous
- Targeted: Near area of interest
- Topical: Apply directly to skin/scalp
Timing & Storage
- Morning or evening, consistent time
- Topical after cleansing, AM and PM
- Refrigerate 2-8°C reconstituted
- Use within 30 days
Expected Timeline
Week 1-2
Collagen synthesis activation. Subtle skin texture improvement. Mild flushing at injection site.
Week 3-4
Noticeable skin quality - increased hydration, smoother texture. Reduced fine lines. Hair follicle stimulation begins.
Week 5-8
Significant skin rejuvenation. Improved wound healing and scar appearance. Hair thickness improvements.
Week 9-12
Peak results for topical protocols. Sustained anti-aging effects. Hair density improvements. Skin elasticity improved.
Side Effects
Common
- Injection site redness (copper vasodilation)
- Mild warmth/flushing
- Temporary skin irritation (topical, rare)
Precautions
- Avoid with active cancer (angiogenesis)
- Monitor serum copper if extended use
- Allergic reaction to copper complex (rare)
