EVIDENCE TAKEAWAY

The short answer.

GHK-Cu is biologically active and has limited topical human research, but the evidence does not validate broad injectable, systemic, or anti-aging claims.

HUMAN VS PRECLINICAL

What evidence exists for GHK-Cu?

HUMAN EVIDENCE
2/5 · Small topical studies

Limited topical research exists, including a 13-patient randomized study that did not show objective improvement in most measured outcomes.

PRECLINICAL EVIDENCE
3/5 · Broad laboratory interest

Cell, skin, and wound-remodeling literature is broader than the decision-grade human evidence.
