Due to a small change in the molecule, the drug lasts for weeks instead of minutes in our bodies
Now I realize, I was sick
Once absorbed, it triggers several biological actions relevant to skin health: Stimulation of collagen synthesis : Upregulates collagen I and III production Elastin production and glycosaminoglycan support : Promotes sulfated glycosaminoglycan synthesis Matrix regulation : Balances MMPs and TIMPs to maintain connective tissue integrity Growth factor upregulation : Increases growth factors such as VEGF, BDNF, and BMP-2, which are crucial for wound healing and tissue regeneration Antioxidant and anti-inflammatory activity : Demonstrates GHK-Cu's ability to act as an antioxidant and anti-inflammatory agent by neutralizing reactive oxygen species (ROS), modulating inflammatory markers, and protecting skin cells from environmental damage The peptides origin as a collagen fragment released after tissue injury explains its role as a natural signal peptide for repair and tissue remodeling

Activation of the gut-brain-muscle axis occurs as GLP-1 signaling engages dual circuits linking vagal afferent inputs to hypothalamic pathways, coordinating neuroendocrine outputs such as insulin-like growth factor-1 (IGF-1) signaling and sympathetic nervous system (SNS) activity that help maintain muscle mass and strength during aging [158-160]
