[153] Due to their small population and resulting reduced effectivity of natural selection, Neanderthals accumulated several weakly harmful mutations, which were introduced to and slowly selected out of the much larger modern human population
Simultaneously, GHK-Cu appears to support matrix metalloproteinases (MMPs) and their inhibitors (TIMPs), suggesting it might regulate both synthesis and degradation of ECM componentsan important attribute for dynamic tissue remodeling
