AHK-Cu
Also known as: Alanine-histidine-lysine copper · L-alanyl-L-histidyl-L-lysine-Cu2+ · Copper tripeptide AHK
Grade describes the published research on the molecule. It is not a quality score, a safety score, or a release state.
What this is
AHK-Cu is a metal-peptide complex. A peptide-only mass or purity result is not enough to describe copper occupancy, oxidation state or final complex composition.
Evidence position
The direct record is centered on cultured cells and ex-vivo follicles, supporting Grade C.
What the record does not establish
Ex-vivo elongation and cell-signaling results do not prove a cosmetic or clinical outcome and do not qualify another formulation or batch.
