what each one is
GHK-Cu
Copper-binding tripeptide · dermal & remodeling research
GHK-Cu is a copper-binding tripeptide, glycyl-L-histidyl-L-lysine complexed with copper(II), that occurs naturally in human plasma. Verve supplies it as a high-purity research compound for dermal and tissue-remodeling research.

Synthetic linear tridecapeptide
Melanotan I, also known as afamelanotide, is a synthetic linear tridecapeptide and a structural analog of alpha-melanocyte-stimulating hormone (alpha-MSH), the endogenous ligand of the melanocortin receptor family. Substitutions to the native alpha-MSH sequence give the analog greater resistance to enzymatic degradation, which is why it is frequently selected as a stable reference ligand in melanocortin-pathway research.
