Similarly, Sp treatment resulted in maintained mitochondrial complex I activity which is found to be disrupted in PD patients and Parkinsonian models (Fig
These substances can affect neuronal activity in both the surrounding and CNSs (Li et al., 2024)

Recent studies have found that increased level of GLP-1 in the hippocampus restores GABA and reverses this neurotoxic effect by reducing oxidative stress through the SIRT1/Nrf2/HO-1 pathway, promoting autophagy through the AMPK/mTOR pathway, and alleviating hippocampal apoptosis by inactivating pro-apoptotic kinase GSK-3 (Nrgaard et al., 2022)
Using GHK-Cu without medically supervised oversight especially when stacking with other peptides, microneedling, laser resurfacing, or hair restoration therapies can significantly limit effectiveness, delay visible improvements, and produce inconsistent outcomes that retail products and non-medical providers simply cannot course-correct
