Research Mechanism Summary
AHK-Cu (L-Ala-L-His-L-Lys-Cu2+) is a copper-chelated tripeptide differing from GHK-Cu by one amino acid (alanine replaces glycine). In an in vitro study using human dermal papilla cells, AHK-Cu at 10⁻¹² to 10⁻⁹ M concentrations significantly increased hair follicle elongation (p<0.001) and DPC proliferation (p<0.001), while reducing the pro-apoptotic markers cleaved caspase-3 by 42.7% and PARP by 77.5% (Arch Pharmacal Res, 2007; https://hairgenetix.com/blogs/articles/copper-peptide-ahk-cu-hair-follicle-growth-study-2007). The copper ion facilitates angiogenic signaling through VEGF upregulation and modulates TGF-β1, both relevant to follicle vascularization and androgenetic alopecia models. Fibroblast studies additionally note that AHK-Cu increases collagen type I synthesis and fibroblast viability, consistent with broader copper-peptide extracellular matrix biology (https://biotechpeptides.com/2025/01/06/ahk-cu-peptide-and-epithelial-tissues/).
