2 However, since GLP-1 is easily degraded within a few minutes by dipeptidyl peptidase 4 (DPP-4), the GLP-1 receptor agonist such as Exenatide and Liraglutide are used to prolong this effect
What the most-hyped peptide actually has Now the other end of the spectrum: dihexa, the peptide from the 2012 headline
Retatrutide works by targeting three hormones : GLP-1 , GIP , and glucagon
In phase III: Semaglutide 2.4 mg (STEP-1): nausea 44.2%, diarrhea 31.5%, vomiting 24.8% Tirzepatide 15 mg (SURMOUNT-1): nausea 29.2%, diarrhea 23.0%, constipation 16.8% Retatrutide 12 mg (TRIUMPH-1): nausea 37.2%, vomiting 22.0%, diarrhea 27.1% Key observation: tirzepatide shows the most favorable GI profile at equivalent dose, likely tied to the GIP component dampening GLP-1-mediated nausea signaling at the brainstem level
