In GHK-Cu, it denotes that the tripeptide glycyl-L-histidyl-L-lysine (GHK) is bound to a copper(II) ion, forming the copper-peptide complex researchers study the Cu specifically distinguishes the copper-bound complex from the standalone GHK peptide, which research has shown behaves differently without the copper ion attached

DES(1-3) IGF-1 signals through the same IGF1R PI3K/AKT and MAPK/ERK axes as IGF-1 LR3 but, because it lacks the N-terminal extension that confers extended half-life in LR3, its circulating stability is more comparable to native IGF-1
