Investigators working with GHK-Cu spray are typically studying copper-peptide signaling pathways tied to collagen synthesis, antioxidant defense, and tissue remodeling
In general, longer social interaction time and shorter latency to initiate interaction are interpreted as indicators of preserved social behavior
Peptides are amino acids that are normally developed within our system
While saline can be appropriate for isotonic delivery in some contexts, the preservative advantage makes it the only reasonable choice for any protocol that needs to draw from the same vial across more than a single day
GHK-Cu is proposed to function as a repair-associated signal that may engage fibroblasts, immune cells, enzymes, ion channels, and cell-surface receptors in laboratory models, with copper itself potentially central to collagen formation, inflammatory signaling adjustment, and antioxidant activity in these settings, as noted by Maquart et al
