Where it sits
Research peptides are short amino-acid sequences supplied either as a lyophilised powder in a sealed vial or already in solution in a pre-filled pen. Which of the two you receive changes how the item is stored and how long it stays usable once opened.
Other names
GHK-Cu is also written as Copper peptide and glycyl-L-histidyl-L-lysine. The same molecule appears under more than one name, which is worth knowing when comparing listings between suppliers.
