AHK-Cu vs GHK-Cu: Copper Peptides for Hair Research
AHK-Cu (Copper Tripeptide-3) and GHK-Cu (Copper Tripeptide-1) are structurally distinct copper peptides — GHK-Cu has the broader hair/skin literature, AHK-Cu is studied more narrowly for follicular vascularization, and both remain preclinical. For research use
