Also known as: Copper peptide GHK-Cu, copper tripeptide-1
GHK-Cu is the copper tripeptide, a three residue peptide (glycyl-histidyl-lysine) bound to a copper ion, listed in catalogs as GHK Cu, copper peptide GHK-Cu, or copper tripeptide-1. It is filed under the cosmetic category, and vendors most often carry it as research-use-only lyophilized powder in vials, though a few also list it in topical formats. Supply is steady, so the vendor spread tends to be moderate rather than wild.
Since GHK-Cu powder is sold by milligram content per vial and pack sizes vary, cost per mg is the metric that lines competing vials up honestly. The grid above folds a shipping estimate into each listing and divides by total milligrams, so a cheaper sticker on a smaller vial does not fool the ranking.
GHK-Cu anchors blended SKUs such as the Glow stack and Klow stack. Before buying, weigh a blend against single vials on the stack planner.
