Copper peptides, particularly GHK-Cu, are naturally occurring protein fragments with a high affinity for copper ions. They are believed to support healthspan primarily by promoting skin rejuvenation, stimulating collagen and elastin production, accelerating wound healing, and exerting anti-inflammatory and antioxidant effects. While most evidence supports topical benefits for skin health, research explores their potential for systemic tissue repair.
Verdict
A promising topical agent for skin health, not a systemic longevity intervention.

Protocol
- Apply a 1-3% concentration serum or cream to the face or scalp once daily.
- Injectable forms are used experimentally and lack standardized healthspan protocols.
Flags
- Systemic (injectable) use lacks long-term human safety data and is highly experimental.
- Product quality and peptide concentration can vary significantly between brands.
- Potential for skin irritation or allergic reaction in sensitive individuals.
- Excess systemic copper can be pro-oxidant; oral/injectable use requires careful consideration.
