Peptide
AHK-Cu
SaveThe copper complex of the AHK tripeptide, studied for skin-regenerative and hair-growth properties similar to GHK-Cu.
Quick verdict
Less studied than GHK-Cu but shares a similar copper-peptide mechanism. Evidence is predominantly preclinical and cosmetic-grade.
Evidence score
A rough internal score reflecting quantity, quality, and consistency of human evidence. Not a clinical recommendation.
What the research shows
Limited independent literature. Some in-vitro data on fibroblast stimulation. Often referenced alongside GHK-Cu research.
Benefits
- May promote collagen synthesis topically
- Potential hair-follicle stimulation in preclinical models
Dosage notes
Topical application in cosmetic serums at proprietary concentrations.
Side effects
- Skin irritation
- Possible copper sensitivity reactions
Who should be cautious
For topical cosmetic use only. Not a regulated therapeutic.
What this page cannot tell you
Far less studied than GHK-Cu. Claims are largely extrapolated from the broader copper-peptide literature.
