I'm not really sure where to place this thread, perhaps the Spa section would be more applicable, but I digress.

I'm looking for people's experience with copper peptide GHK-cu, which is commonly sold under PAL-GHK. Apparently, it's great for anti-aging.

There's a slew of information on the Wikipedia page, however I want some real life feedback, specifically about its cosmetic benefits and affects on hair regrowth!
