ghk-cu target GHK‐Cu directly bound and activated SIRT1. (A) Process of Copper Peptide Before and After:

I'm sure that's the case [but of course that's only my opinion!] Sometimes I simply write these things on the fly, and should review them before I post

Skin Firmness, Texture, and Visible Aging According to the International Journal of Molecular Sciences , GHK-Cu's small size and ability to bind to copper allow it to participate in copper metabolism, which may affect certain age-related processes in the body

Peptides are often synthesized in small batches, which can drive up production costs compared to mass-produced pharmaceuticals

This strategy is great for those who want a "shield" for the day ahead

Studies comparing GHK (apo) vs GHK-Cu consistently show reduced activity for the copper-free peptide

Compared with GHK alone, both chimeric peptides increased anti-oxidative and anti-apoptotic activities
