[TODO] Hook — three generations of incretin-based peptides (mono → dual → triple agonist), why researchers compare them, what this guide covers
[IMAGE: Side-by-side comparison infographic — 3 columns: Semaglutide / Tirzepatide / Retatrutide with key stats]
Quick Comparison
- [TODO] Table: Receptor targets — GLP-1 only vs GLP-1+GIP vs GLP-1+GIP+GCGR
- [TODO] Table: Max weight reduction in trials — ~15% vs ~22% vs ~24%
- [TODO] Table: Half-life — ~7d vs ~5d vs ~6d
- [TODO] Table: Developer — Novo Nordisk vs Eli Lilly vs Eli Lilly
- [TODO] Table: Approval status — FDA approved vs FDA approved vs Phase 3
Semaglutide Profile
- [TODO] GLP-1 mono-agonist, longest track record, most safety data
- [TODO] STEP/SELECT/FLOW trials — weight, CV, renal outcomes
- [TODO] Established titration protocol, well-characterized side effect profile
Tirzepatide Profile
- [TODO] First dual GLP-1/GIP agonist, superior to semaglutide in SURPASS-2
- [TODO] Unique GIP component — may reduce nausea vs pure GLP-1 agonists
- [TODO] Broader metabolic effects — insulin sensitivity, lipid metabolism
Retatrutide Profile
- [TODO] Triple agonist — adds glucagon receptor for energy expenditure
- [TODO] Highest weight reduction in Phase 2 data, liver fat reduction notable
- [TODO] Least clinical data — Phase 2 only, Phase 3 ongoing
Head-to-Head Research Findings
[IMAGE: Bar chart comparing weight reduction percentages across landmark trials]
- [TODO] Efficacy progression — each generation shows numerically greater weight reduction
- [TODO] Cross-trial comparison caveats — different populations, durations, titration schedules
- [TODO] GI tolerability — triple agonist does not appear significantly worse
- [TODO] Metabolic markers — liver fat, lipids, HbA1c across all three
Choosing Between Them (Research Context)
- [TODO] Most established data → Semaglutide
- [TODO] Best efficacy with approval → Tirzepatide
- [TODO] Highest preliminary efficacy → Retatrutide
- [TODO] Research availability, cost, protocol design considerations
