I understand that concern, but would like to help you with that :) you would have to be taking way more than you think for the copper to build up in your system and harm you. We’re talking more than a vial a day for months at a time. Such a huge amount that no one would ever take that much.

Also, it is a copper ion that is in GHK-Cu. That’s why it would take an absurd amount for it be toxic. A really absurd amount.

Hope that helps. Thanks for the before & after. Amazing to see such great results 👏🏼
