GHK-Cu
Copper peptideGlycyl-L-histidyl-L-lysine-Cu
Naturally occurring copper-binding tripeptide. Well-documented in dermatology literature for collagen synthesis and wound healing.
§ 01
Research notes
Mechanism
GHK-Cu is a copper-binding tripeptide that occurs naturally in human plasma. It's one of the most-studied peptides in dermatology with decades of literature on wound healing, collagen synthesis, and anti-inflammatory activity.
Research dosing
Topical formulations at 0.05–0.2% concentration are the most common research format. Subcutaneous research protocols use 1–2 mg per dose, less commonly than topical.
Vendor coverage
GHK-Cu is widely stocked but quality varies considerably. The peptide's copper binding makes purity assessment more involved than standard peptides — the COA must verify both the tripeptide and the copper coordination. Top vendors include both metrics; bottom-tier vendors often only report tripeptide purity.
