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

BC is closely related with global warming and at present is continuously deteriorating the environmental and human health 7,8
A blood glucose level of 54 mg/dL or less was reported in 26% of patients receiving the 7 mg tablets, 30% of patients receiving the 14 mg tablets, and 32% with placebo
While straightforward in principle, manual calculations can be time-consuming especially when switching between mg, mcg, and different syringe types
