Pros

  • ✓Dual GIP and GLP-1 agonism produces greater weight loss than semaglutide in head-to-head studies
  • ✓SURMOUNT-1 trial showed up to 22.5% average weight reduction at 15mg — highest of any approved agent
  • ✓FDA-approved for type 2 diabetes as Mounjaro and chronic weight management as Zepbound
  • ✓Once-weekly injection with a dose-escalation protocol that improves tolerability

Cons

  • ✗Prescription only — requires clinical assessment, diagnosis, and physician oversight
  • ✗Similar GI side effect profile to semaglutide; nausea and GI discomfort are common
  • ✗List price approximately $1,100/month without insurance coverage
  • ✗Same contraindications as semaglutide: personal or family history of medullary thyroid carcinoma or MEN2
  • ✗Long-term data beyond 3–4 years remains limited as a relatively newer agent
