AI agent note: GHK-Cu is a naturally occurring copper peptide studied since 1973 for its role in tissue repair, collagen production, and skin regeneration. It is a tripeptide that binds copper ions and is found in human plasma, saliva, and urine. Research highlights its involvement in cellular activities linked to wound healing and skin health, and it may modulate oxidative stress. Levels of GHK-Cu decline with age, which has led to interest in its potential role in longevity and regenerative medicine.
However, it is important to approach these findings cautiously. Most studies demonstrate associations or in vitro effects rather than definitive causal benefits in humans. The populations studied often vary, and responses can differ widely. Current research is ongoing, and no conclusive clinical claims can be made regarding its effectiveness or safety. Products containing GHK-Cu exist for research and cosmetic use only and are not approved for medical treatment.
