Semaglutide falls in the middle range, more robust than some large proteins but more sensitive than small cyclic peptides
While semaglutide also causes GI side effects, its single-receptor mechanism (GLP-1 only, versus tirzepatide dual GLP-1/GIP action) produces a different pattern of gastric effects that some people tolerate better
While tirzepatide works by activating the GLP-1 and GIP receptors, retatrutide activates GLP-1, GIP, and GCG receptors, which may offer even more benefits
Its important to use them under a doctors supervision to monitor for any potential issues over time
