GHK-Cu
GHK-Cu is a naturally occurring copper tripeptide found in human plasma, saliva, and urine.
Also known as: Copper Peptide, Skin Regeneration & Anti-Aging Compound
Overview
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
- Collagen Synthesis
- Wound Healing
- Anti-Aging Effects
Enhanced collagen production, improved skin elasticity, reduced fine lines and wrinkles, accelerated wound healing, hair growth stimulation, convenient daily application
Mechanism of Action
Topical GHK-Cu penetrates skin layers to deliver copper directly to target tissues. Activates fibroblasts, stimulates collagen and elastin synthesis, promotes angiogenesis, and modulates inflammatory responses for optimal skin regeneration
Pharmacokinetics
Peak plasma concentration: 3 min. Elimination half-life: 4 min. Largely cleared by: ~21 min.
Research Protocols Injectable
| Goal | Dose | Frequency | Route |

| Hair growth stimulation | 1-2% solution | 1x daily | Subcutaneous |
| Wound healing | 1-2% gel | 2-3x daily | Subcutaneous |
| General skin health | 0.5% serum | 1x daily | Subcutaneous |
| Intensive repair | 2% cream | 1x daily | Subcutaneous |

Peptide Interactions
- BPC-157 — Synergistic: Enhanced wound healing and tissue repair when used together
- TB-500 — Synergistic: Different healing pathways that work well in combination
- Melanotan II — Use Caution: Both affect melanin production, monitor for skin discoloration
- Copper Supplements — Avoid combination: Risk of copper toxicity when combined with additional copper sources
- CJC-1295 — Compatible: Growth hormone effects may complement collagen synthesis
- Iron Chelators — Monitor Combination: May interfere with copper binding and peptide effectiveness
Peptide Instructions Injectable
Supplies:
- GHK-Cu topical formulation (serum, cream, or gel)
- Clean hands and application area
- Gentle cleanser for prep
- Moisturizer (if using serum)
- Sunscreen for daytime use
How to Reconstitute Injectable
- 1Cleanse skin thoroughly with gentle cleanser
- 2Pat skin dry and wait 5 minutes for complete drying
- 3Apply thin, even layer of GHK-Cu product to target areas
- 4Massage gently until fully absorbed (1-2 minutes)
- 5Follow with moisturizer if using serum formulation
- 6Always apply sunscreen during daytime use
What to Expect Injectable
Week 1-2: Improved skin texture and hydration. Week 3-4: Reduction in fine lines and skin smoothness. Week 6-8: Enhanced skin firmness and elasticity. Week 8-12: Visible improvement in skin tone and clarity. Hair growth: 6-12 weeks for initial results. Most effective for: Anti-aging, skin regeneration, hair growth.
Side Effects & Safety
Patch test before first use to check for sensitivity. May cause mild skin irritation initially (usually resolves). Always use sunscreen as copper peptides can increase photosensitivity. Avoid contact with eyes and mucous membranes. Discontinue if severe irritation or allergic reaction occurs.
