Why labs pair them

Retatrutide acts on the GLP-1, GIP and glucagon receptors and leads metabolic research today.
GHK-Cu is a copper-binding peptide the body makes itself. Lab studies link it to genes for collagen, skin and tissue repair.
Labs working on metabolic models often add skin and tissue work to the same project, which is why the two are searched for together.
