What is it? GHK-Cu is a copper peptide naturally found in your blood. It decreases with age - by 60, you have about 1/3 the amount you had at 20.
What it does: It triggers your body's repair processes - stimulating collagen, improving wound healing, promoting hair growth, and reducing inflammation.
Two ways to use it: Subcutaneous injection for systemic effects, or topical application for localized skin benefits.

What to Expect (Timeline)
Skin may feel slightly tighter. Healing wounds show improved progress. Most people don't notice much yet - be patient.
Noticeable improvements in skin texture and tone. Hair may appear fuller/thicker. Fine lines may soften.
Collagen remodeling well underway. Significant skin improvements. Hair growth may be more visible.
Full effects visible. Continued improvement with cycling. Best results with consistent use over time.
Frequently Asked Questions
GHK-Cu is a tripeptide (3 amino acids) bound to copper that naturally exists in your blood. It acts as a signaling molecule that tells your body to repair and regenerate tissue. When you're young, you have plenty of it. By age 60, levels drop to about 1/3. Supplementing restores these signaling capabilities.
It depends on your goals:
- Topical: Best for localized skin concerns (face, specific areas). Easier, no needles.
- Injection: Systemic effects throughout body. Better for overall anti-aging, hair growth, internal healing.
- Both: Many people do both for maximum benefit.
Cycling (20-30 days on, 1-2 weeks off) prevents receptor desensitization and allows your body to process the changes. It also matches how your body naturally produces these peptides - in cycles, not continuously. Some people use it continuously at lower doses, but most find cycling more effective.
Yes! GHK-Cu combines well with:
- BPC-157: For healing protocols - they complement each other
- TB-500: Enhanced tissue repair
- Ipamorelin/CJC-1295: GH peptides for overall anti-aging
GHK-Cu doesn't compete with other peptides and has no significant interactions.
