GHK-Cu (Copper-GHK) is a bioactive peptide known for its anti-aging, skin-repairing, and systemic healing properties. While traditionally used in injectable or topical for

ms, intranasal GHK-Cu is gaining interest for its potential cognitive and systemic benefits.

🔬 How GHK-Cu Works

• Stimulates collagen & elastin → improves skin repair, reduces wrinkles.
• Anti-inflammatory & antioxidant → protects against cellular damage.
• Promotes wound healing & tissue regeneration (used in burns, scars).
• May enhance cognitive function (via neuroprotection and angiogenesis).
• Supports hair growth (by activating follicle stem cells).

👃 GHK-Cu Nasal Spray: Pros & Cons

✅ Potential Benefits of Intranasal Use

✔ Faster absorption than oral (bypasses digestion).
✔ Possible brain benefits (nasal route may enhance delivery to CNS).
✔ No injections needed (convenient for daily use).
✔ Systemic anti-aging effects (skin, joints, immune support).

❌ Possible Downsides

• Lower bioavailability than subcutaneous injections.
• Nasal irritation (some users report temporary stinging).
• Limited human studies on nasal absorption (most research is on injections/topicals).

💉 GHK-Cu Nasal vs. Other Routes

📊 Dosage & Usage Guide

For Nasal Spray (Research Guidelines)

• Dose per spray: ~1-2 mg (varies by formulation).
• Frequency: 1-2 sprays per day (morning/night).
• Cycle: Can be used daily (no known receptor desensitization).

For Subcutaneous Injection (Research guidelines)

• Typical dose: 1-2 mg/day (often mixed with BPC-157 for healing).

• 🧠 Potential Cognitive & Anti-Aging Effects

🔹 Neuroprotection (may help with brain fog, memory).
🔹 Reduces oxidative stress (linked to slower aging).
🔹 Improves skin texture (collagen boost).
🔹 Speeds up injury recovery (tendons, joints).

⚠️ Side Effects & Safety

• Temporary nasal discomfort (burning sensation).
• Metallic taste (common with copper peptides).
• Very low systemic toxicity (studies show high safety profile).

💡 Final Verdict

✅ GHK-Cu nasal spray  research is promising for anti-aging, skin, and brain health, but injections/topicals may be more potent for deep tissue repair.
