Dear Zaril:


Regarding if they would be "complimentary or work on the same mechanisms", GHK-Cu is a copper peptide / But it seems both generations (1st and 2nd) of copper peptides have produced amazing results as far as skin beautification.


So as far as topical cosmetics are concerned, it seems that a mix of both generations would be the best of both worlds (or use a potent concentration of GHK-Cu).


But in particular, GHK-Cu seems to have even wider human health potential - For more information see:


Best Wishes,
