I’ve read that testing blends is pointless bc you can’t isolate and evaluate one ingredient at a time. Is that true? would that be true for GHK-CU?

I only use ghk-cu, for that reason, then I know.
I have some nice results now after 6 weeks, my face wrinkles are less deep.
I hope. I may be seeing things, lol
