Unlike larger proteins, they interact directly with receptors and pathways involved in healing, hormone regulation, immune function, and cellular communication
They carry signals between cells, telling your body what to build, repair, produce, and regulate
Some people may prefer to take more social downtime, as mild side effects like redness, bruising, swelling or dryness may still be present during the first week of recovery

Effects on extracellular matrix and collagen biology One of the best-characterized biological footprints of GHK-Cu is its effects on extracellular matrix biology, particularly collagen and elastin
It increases VEGF receptor activity to promote new blood vessel formation, enhances collagen synthesis and organization, activates the ERK1/2 signaling pathway for cell proliferation and migration, and modulates inflammatory responses to optimize healing conditions
