Articles on GHK-Cu, the copper-binding tripeptide studied in collagen and gene-expression research, and on sourcing it in Canada for laboratory use.
What oxidative stress actually means, how the Keap1-Nrf2 switch works, why Nrf2 controls glutathione synthesis, what happened when antioxidants and an Nrf2 activator were put into large trials, and why the GHK-Cu Nrf2 claim does not hold up.
Anti-aging peptides explained: GHK-Cu, Epitalon, MOTS-c, SS-31, FOXO4-DRI and more, mapped to the hallmarks of ageing they target, plus sourcing in Canada.
What is GHK-Cu? A Canadian guide to the copper tripeptide: its 1973 discovery, collagen and gene-expression research, the evidence gaps, and sourcing.
