Has anyone used GHK-CU for collagen loss?

This peptide sounds like it would be helpful for people suffering from aged appearance.
" It stimulates blood vessel and nerve outgrowth, increases collagen, elastin, and glycosaminoglycan synthesis, as well as supports the function of dermal fibroblasts"
“GHK has also been found to switch cellular gene expression from a diseased state to a healthier state for certain cancers and for chronic obstructive pulmonary disease (COPD).”

Can’t really find it mentioned elsewhere on the forum, but there are lots of studies available online stating it’s benefits.
