About AHK-Cu

AHK-Cu is a copper-binding tripeptide (alanine-histidine-lysine complexed with copper) studied in dermatological and hair-follicle research models. For teams investigating copper-peptide biology, angiogenic signaling, and follicular cell behavior, it offers a defined, well-characterized coordination complex distinct from the more widely referenced GHK-Cu. Puritide Research supplies AHK-Cu as a high-purity, research-use-only material, prepared for in vitro and ex vivo work and backed by third-party-verified certificates of analysis so your data rests on consistent, documented quality.

What Is AHK-Cu?

AHK-Cu is a copper-complexed tripeptide composed of alanine, histidine, and lysine (Ala-His-Lys), where the imidazole and amine groups coordinate a copper(II) ion. This histidine-centered architecture is the same coordination principle that underlies the broader family of copper-binding peptides, though AHK is a distinct sequence from the well-known glycine-histidine-lysine peptide GHK-Cu.

In experimental settings, AHK-Cu is used to study how copper delivery via a small peptide carrier influences cellular behavior in skin and hair-follicle models. Copper is a cofactor for several enzymes involved in tissue remodeling and angiogenesis, and copper-peptide complexes provide a controlled way to examine these processes in vitro and ex vivo.

Present understanding derives from cell-culture assays and ex vivo tissue models. Findings should be interpreted within their experimental context and not treated as established clinical outcomes. Puritide Research supplies AHK-Cu strictly for laboratory use; it is not approved for human or veterinary application.
