Research overwhelmingly describes the safety of GHK-Cu positively, such as when the authors of a 2018 review called it a safe, inexpensive, extensively studied compound.14 However, even though copper peptides have demonstrated an impressive safety track record in studies, there are (as with most skin care actives) a few safety risks to consider

Missed weeks reset the signaling momentum

It targets an entirely different set of neurons in the brain, creating what researchers call complementary satiety signaling

At its core, GHK-Cu functions as a matrikine, a signaling molecule released from the extracellular matrix when tissue damage occurs
