Copper Peptides (Copper Peptide Complex (AHK-Cu, GHK-Cu variants))
A family of small peptides complexed with copper ions that stimulate collagen synthesis, wound healing, and skin remodeling. Beyond GHK-Cu, includes AHK-Cu and other tripeptide-copper complexes.
How it works
Copper peptides deliver bioavailable copper to tissues while the peptide provides signaling to stimulate collagen I/III synthesis, attract immune cells for remodeling, and promote glycosaminoglycan production.
