2mg is all you need. These tiktok people are something else. Less is more.

Higher doesn’t mean better results either, there’s a bell curve of effectiveness I think.

Can you explain how less is more with ghkcu? Any literature on diminishing returns with larger doses??

I respectfully disagree. Its all completely individual I ran 2mg, saw no returns, ran 5mg, some improvements, I now run 7.5mg ED and this is my individual spot. Surgery and Stab wounds all but gone, very feint now, doubt they will completely disspaper. Mrs runs 5mg and her ketosis Polaris that she has had since birth has vanished. She has tried all manner of OTC/UTC items available and this is the only thing that has touched it.
