GHK-Cu Vendor Comparison - Injectable vs Topical Pricing
GHK-Cu Vendor Comparison
GHK-Cu (Copper Peptide) is available in both injectable and topical formulations. Injectable versions are typically more expensive but offer systemic benefits. Topical versions target skin and hair specifically. Pricing varies dramatically based on formulation, copper binding quality, and testing verification. Below is a breakdown of both markets.

Key Insights
- Copper binding is critical: GHK without properly bound copper has minimal activity; verify with COA
- Injectable price range: $32-58 for 50mg; 81% premium for highest vs lowest
- Topical better for skin/hair: Direct application more efficient for cosmetic goals; cheaper per application
- Injectable for systemic: Anti-inflammatory, gut healing, overall recovery benefits require injection
- Testing verification: Only 4 out of 7 injectable vendors confirm copper binding via proper testing
- DIY topical caution: Mixing your own requires proper pH and copper sulfate ratio (not recommended without chemistry knowledge)
