copper tri-peptide vs. soy protein mixed with copper chloride??

What's the difference? Is one less effective than the other?

Dear Sam89:

Great question! You'll find that we've addressed this question at: https://healthyskin.infopop.cc/...901032216#9901032216

There you will read that more than trying to figure out which one is "stronger", the best way to think about it is: Which one is better suited for certain skin rejuvenation task (a more accurate phrase).

Some client's skin may actually do better using the milder 1st generation products (GHK based), which typically are milder than 2nd generation products.
