Truthfully, while there is still some promising research around GHK when taken orally, most of these claims should be taken with a grain of salt

Most people need several weeks to a few months of consistent use before judging GHK-Cu

Thus, while arrestin binding will sterically block G protein activation and prevent some forms of signaling (membrane-delimited ion channel regulation), arrestin has a scaffolding function that enables MOR activation of the ERK1/2 MAPK pathway (Macey et al., 2006

More significant changes in hair density appearance typically become visible around 6-8 weeks
