02 / Mechanism in the literature
The GHK sequence binds copper ions and, in research models, influences collagen and glycosaminoglycan synthesis, wound-remodeling signaling, and antioxidant pathways. The copper complex is essential to its activity.
03 / Research context
GHK-Cu appears extensively in dermal, hair-follicle, and tissue-remodeling literature as a regenerative copper peptide.

04 / Common questions
Why does the copper matter?
The GHK peptide's activity in research depends on its copper complex — the 'Cu' is part of the active molecule, not incidental.
How does this differ from the 100 mg record?
Same molecule and specification; only the listed fill mass differs.
