Research Notes
GHK-Cu is the copper(II)-bound complex of the naturally occurring tripeptide Gly-His-Lys. The GHK sequence is present in human plasma, saliva, and urine, and its copper-binding affinity is the basis for most studied biological effects.
Research interest
GHK-Cu has been investigated in preclinical and dermatological models for:
- Fibroblast proliferation and collagen synthesis
- Antioxidant signaling and hydroxyl radical quenching
- Wound healing and angiogenic models
- Hair follicle stem cell models
- Gene expression modulation (multiple transcriptomic studies)
