ghk cu gene expression connectivity map and in Cancer Suppressors Exploring the Role of Tripeptides

In the rats that received GHK-Cu, the researchers found an increase in total protein and collagen synthesis greater than that of the placebo group, demonstrating that GHK-Cu is able to increase extracellular matrix accumulation in wounds in vivo .28 Are GHK-Cu copper peptides safe

The Leyden 2002 clinical evaluation in the Journal of Cosmetic Dermatology compared a copper tripeptide cream and serum against placebo in 67 women with photodamaged skin and found significant improvements in wrinkle depth, skin laxity, clarity, and density at 12 weeks [30]

It might also work as an antioxidant, protecting your cells against damage caused by oxidative stress
