Dear SB and Dr Pickart,

I am worried reading alot about the untraceability of "ingredients" of manufactured products. With the health hazards of foodstuff from China, I was wondering whther SB gets any of its components/ingredients from there?

My second question is: What is the difference between Super GHK Copper Serum and the older Super CP Serum? Which is stronger?

Thank you!

We buy our ingredients from reputable companies in the USA but most of them buy their products from China. We depend on their quality control.

It is very difficult to manufacture chemicals in the USA today because of many regulations.

The older Super CP Serum is stronger but the Super GHK Copper works well on very sensitive skin such as around the eyes.
