How It Works
Mechanism of action
Copper-binding tripeptide found naturally in plasma and saliva. Used topically at 1–3% (face) and 2–5% (scalp) in prescriber-directed formulas.
Did you know?
GHK-Cu's striking pale blue color comes from the copper ion at its core — the same chemistry that makes the Statue of Liberty green.
What compounding can change
When GHK-Cu is compounded for one patient, your prescriber can choose the concentration, combine it with other ingredients, and pick the base. Commercial products come in fixed strengths and bases.

Please note: Compounded medications require a prescription from a licensed prescriber for an individual patient. Compounded medications are not FDA-approved. The FDA does not review them for safety, effectiveness or quality. A compounded medication is not the same as, or a generic version of, any FDA-approved drug.
