The peptide affects the nitric oxide system, which could theoretically interact with blood pressure medications or other cardiovascular drugs
Of note, pharmacologically induced PFC NMDAR hypofunction leads to increased oscillations [99] while genetic deletion of NMDAR1 subunits in pyramidal neurons increases oscillations, cell excitability and sEPSC frequency [100], similar to the present data
It may help protect neurons and support better focus and clarity
For individuals with Wilson's disease (a genetic disorder causing copper accumulation) or other copper metabolism disorders, theoretical caution is warranted, though even in these populations topical GHK-Cu is unlikely to pose significant risk given the minimal systemic absorption
Understanding how to read a peptide COA is an important research skill
