GHK is a naturally occurring bioactive amino that forms an ionic complex with copper in human plasma. As we age, normal levels of GHK-Cu decrease. It is thought that lower levels influence impaired wound healing and immune dysfunction among other age-related declines. 

Replenishing physiological levels of GHK-Cu has been shown to aid in powerful regenerative and reparative longevity actions including collagen and elastin synthesis, DNA repair, stem cell renewal processes, healthy inflammatory, neurological, and cardiovascular function, and a reset to epigenetic programming.
