Sounds like this is a less popular opinion here but my wife and I ran the klow mix at 5mg/day copper split 2x a day for 12 weeks. We both saw pretty significant changes in skin. We're older but both of us saw pretty significant reduction in wrinkles on our faces. For me it was around the eyes. Wrinkles are almost gone. She also saw pretty significant improvement around her chest. I used to tell her that her cleavage was starting to look like some old leathery Harley bitch. Her skin significantly smoothed out there too. We did before and after pics to make sure we weren't wasting our money or just buying into hype.
I'll probably run that cycle 12 on 12 off for the rest of my life. I'm almost 50 though so there's more skin issues to correct.
Quick note on the Harley bitch comment, she's smoking hot and takes it pretty well. Didn't want to come across sounding abusive. I save the abuse for burnt dinners.
