Researchers discovered that the bodys natural GLP-1 system activates specific brain cells called GABA neurons (gamma-aminobutyric acid) in a region called the ventral tegmental area, or VTA
Other red flags include dark urine or yellowing of the skin, which may indicate liver distress, or sudden swelling and decreased urination, which can signal kidney strain
Notably, fiber photometry also revealed that systemic administration of GLP-1 [149] and liraglutide [148] does not affect the activity of ARC AgRP/NPY neurons, emphasizing how findings from patch-clamp electrophysiology experiments on hypothalamic slices can differ from the situation in vivo
Patients who report feeling less bloated on GHK-Cu are likely experiencing a secondary effect of its systemic inflammation reduction rather than any specific metabolic action
