What researchers study
AHK-Cu is the copper complex of the tripeptide alanyl-L-histidyl-L-lysine, a relative of GHK-Cu. It has been studied in cultured dermal papilla cells and ex vivo human hair follicles.
Research areas
- Dermal papilla cell proliferation assays
- Ex vivo human hair-follicle elongation
- Skin-matrix and fibroblast studies
- Copper-peptide structure-activity comparisons
Reported findings
Summaries of published results. Each one is tagged with the type of study behind it. They describe research outcomes and are not claims about any product. Why study type matters.
- cell culture
AHK-Cu stimulated elongation of human hair follicles ex vivo and proliferation of dermal papilla cells in culture
- cell culture
AHK-Cu raised the Bcl-2/Bax ratio and lowered cleaved caspase-3 and PARP in dermal papilla cells
