Side effects of Topical GHK-Cu have not been widely reported and it is considered generally safe, particularly at typical cosmetic usage concentrations

Illustratively, it is produced in the central nervous system (i.e., brainstems raphe nuclei) (12% of the serotonin in the human body), skin (i.e., Merkel cells), lung (pulmonary neuroendocrine cells), gastrointestinal tract (90% of the serotonin in the human body) (i.e., enterochromaffin cells), and rest of 8% is stored in platelets [166]
