How is GHK-Cu administered?
This describes how GHK-Cu is typically administered in clinical and research references, not a self-administration guide. The usual route is Sub-q (systemic) or topical (skin), on a daily schedule, generally over 4-6 weeks. Specific dosing is individual and beyond general information, and human evidence for GHK-Cu is limited.
