Can GHK-Cu + Tretinoin be used in the same stack?

[cay9999999]

I’m on .1% tret and 2 weeks in I’m going through quite a bad purging phase. Since tret helps with acne, skin texture, and collagen production, while GHK-Cu is supposed to help with skin repair and collagen. Would they complement each other or is there any reason to avoid stacking them?
