Research notes

Standard FDA titration for Mounjaro/Zepbound. Same molecule, same dosing ladder. Each step held 4 weeks minimum. If missing dose: take if >72 hours until next dose; otherwise skip. Dual GLP-1/GIP agonist — typically better GI tolerance than retatrutide at equivalent weight-loss efficacy.
