That is why protein intake and resistance training are the two non-negotiables of any GLP-1 routine, and why the smartest supplement choices are the ones that defend muscle and fill the specific holes lower intake leaves behind
In 1992, Eng published his discovery of this novel peptide in the Journal of Biological Chemistry , naming it exendin-4
