Sale framing
Research-use-only posture: Same posture as other peptides — RUO label is not a safe harbor when human-use intent is evident for injectable forms.
Personal possession: Not federally scheduled. Topical cosmetic GHK-Cu is sold OTC in skincare; injectable forms are in a different regulatory category.
