mechanism
How it works.
GHK-Cu is a naturally occurring copper-binding tripeptide* (glycyl-L-histidyl-L-lysine) that declines with age in human plasma. Preclinical research has explored its role in fibroblast activation, collagen and glycosaminoglycan synthesis, and copper ion transport into dermal tissue.
- ↳Gly-His-Lys + Cu²⁺
Beyond dermal applications, studies have investigated GHK-Cu for wound repair and gene-regulatory activity, with transcriptomic work suggesting it may modulate hundreds of genes* related to tissue remodelling.
- ↳Pickart 2018 — ~4192 up/down
At clinical dosing* — the range used in peer-reviewed research rather than cosmetic formulation — GHK-Cu sits at an entirely different concentration than serums labelled with the same peptide.

“The copper peptide arrived in protective packaging — vial color was consistent with what the product page showed. Lot was traceable through the COA lookup. Clean process.”
Jessica K · Toronto✓ verified
“Bought the 100mg size. Reconstitution instructions on the product page were specific to copper peptides which I appreciated — most generic peptide guides don’t address the colour considerations.”
Natalia G · Montreal✓ verified
“Shipping was discreet, vial sealed correctly. Wish the product page had a side-by-side comparison with the GLOW formula — had to email customer service to clarify the difference, which they did answer well.”
