The reason the menu has two versions is that face and body procedures call for different emphasis on the recovery side, and the right blend tracks the operation
GHK-Cu Research Applications Collagen, decorin and matrix-metalloproteinase gene expression in dermal fibroblast cultures
It represents the biologically active fragment of the larger endogenous Body Protection Compound (BPC, MW ~40,000 Da), the smallest sequence retaining BPCs full biological activity profile
This is related to the copper component
Why Researchers Track This Decline The plasma decline matters to researchers because GHK-Cus concentration appears to track closely with markers of tissue repair capacity, making it a useful reference point for studying how cellular regeneration and extracellular matrix activity change with age
