Rather than simply asking "What does this peptide do?", fragment research allows scientists to ask: "Which part of the peptide is responsible?" And sometimes, those answers lead to entirely new directions for future research
The neurons from hypothalamic paraventricular nucleus (PVN) secrete the tripeptide Thyrotrophin-Releasing Hormone (TRH) in the hypothalamic-pituitary portal system, reaching the anterior pituitary gland

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
For pigmentation-related concerns, changes can take even longer sometimes 36 months of consistent use
Although drinking green tea can lower ALT levels, high concentrations of green tea extract have been associated with hepatotoxicity
