The story
Blue Copper No.1
Copper tripeptide-1 — GHK-Cu — is the peptide that started the modern peptide movement. Naturally present in young skin and in decline with age, it is a tiny signalling molecule with an outsized reputation. Blue Copper No.1 delivers it at a full 1%, stabilised at skin-friendly pH 6.5 in a cushion of five-weight hyaluronic acid. The colour is the proof: true GHK-Cu glows a vivid, saturated blue.
