Safety
For skin use only. Common effects are redness, tingling, dryness and irritation, more likely alongside retinoids, exfoliating acids or benzoyl peroxide. Injectable GHK-Cu is a different product: pharmacies may not compound it, and the FDA has flagged a possible immune-reaction risk.
Talk to a licensed clinician about your health history and every medication you take before you start.
Legal status
Prescription only; compounded and not FDA-approved. GHK-Cu (topical copper peptide) is prepared by a compounding pharmacy for an individual prescription. Compounded products are not FDA-approved, and the FDA does not review them for safety, effectiveness or quality. Non-injectable GHK-Cu is in FDA’s 503A Category 1 (list updated May 14, 2026), so a licensed pharmacy may compound it from a registered source while the FDA evaluates it. The FDA plans to consult its compounding advisory committee before the end of February 2027. Injectable GHK-Cu is in no category and may not be compounded.
What GHK-Cu (topical copper peptide) is
GHK-Cu (topical copper peptide) contains copper tripeptide-1. No GHK-Cu drug has FDA approval. Prescription creams and foams are compounded; copper peptides also appear in cosmetics.
Dosing
Compounded cream or foam for the skin or scalp, applied to the skin or scalp as the prescriber directs. Compounded at strengths such as 0.5%, 2% and 3% creams (AgelessRx and Valhalla Vitality); the prescriber picks the strength.
How well it works
Evidence comes from small cosmetic studies. A 2018 review by researchers who study the peptide reports a 12-week facial cream study in 71 women with sun-aged skin that improved skin density and fine lines, with no large controlled trial and no FDA review. Individual results vary.
