Many researchers find these minor reactions lessen or disappear entirely as their protocol continues
But there's a factor that precedes and outweighs this choice: the quality of the peptide itself
The market is flooded with products made through cheap, large-batch synthesis processes that often result in impurities, incorrect peptide sequences, or lower-than-advertised concentrations
Researchers have proposed that activating multiple pathways simultaneously may provide opportunities to study more comprehensive metabolic signaling responses

Utilizing MRS with ultra-high-field MRI, such as 7 T MRI, addresses this limitation by enhancing the spectral resolution, thereby allowing differentiation of Glu and Gln and even GABA signals [19, 20, 30]
