AHK-Cu

AHK-Cu is a copper peptide made from the three-amino-acid peptide AHK bound to copper. It is studied mainly in skin and hair-follicle research, with special interest in cells called dermal papilla cells that help control the hair-growth cycle. Research has looked at AHK-Cu and hair-follicle growth, dermal papilla cell activity, fibroblasts, and the local skin environment around hair follicles. Compared with GHK-Cu, AHK-Cu has a more focused research profile. That makes it especially interesting for studies centered on hair-follicle biology, copper-peptide signals, and skin-cell behavior.
