What it is
AHK-Cu is a copper-binding tripeptide label used in cosmetic and research discussions. Exact identity and product evidence should be documented separately.
Mechanism and research questions
- Research discussions focus on copper-peptide interactions and skin or follicle-related models.
- The direct literature is too small to establish a consistent receptor, follicle, or skin outcome for every AHK-Cu preparation.
Human evidence
No robust human clinical efficacy evidence was identified in the reviewed sources.
Preclinical / mechanistic evidence
Mechanistic and cosmetic literature may provide hypotheses, but exact product equivalence is unresolved.
Evidence summary
The initial audit located only a small direct PubMed record set; treat the evidence as preliminary until more primary sources are verified.
Limits and interpretation
- Require exact sequence, copper state, purity, and formulation data.
- Do not borrow GHK-Cu claims for AHK-Cu.
- No application or medical protocol is provided.
Regulatory and identity note
