  • Semaglutide
  • GLP-1
  • 14.9%
  • ~7 days
  • Approved (Wegovy, Ozempic)
  • First-generation benchmark. Proven efficacy but receptor desensitization limits long-term sustainability without dose increases
  • Tirzepatide
  • GLP-1 + GIP
  • 20.9%
  • ~5 days
  • Approved (Mounjaro, Zepbound)
  • Dual-receptor mechanism reduces plateau risk. Currently the gold standard for weight loss magnitude
  • Survodutide
  • GLP-1 + Glucagon
  • 18.6%
  • ~6 days
  • Phase 3 (FDA fast-track)
  • Glucagon component adds metabolic rate elevation. Expected approval Q3 2026 based on SYNCHRONIZE-1 data
  • Mazdutide
  • 16.2% (32 weeks)
  • Phase 2b
  • Superior lean mass preservation (22% vs 31–35% typical). Strongest metabolic health profile among current candidates
  • Retatrutide
  • GLP-1 + GIP + Glucagon
  • 24.2% (48 weeks)
  • Phase 2 (Eli Lilly)
  • Triple-receptor agonist. Highest weight loss observed in trials but GI side effects remain dose-limiting for some patients
  • Survodutide and mazdutide represent the immediate next wave. Commercially viable within 12–18 months. Retatrutide's triple-agonist mechanism is mechanistically elegant but faces higher regulatory scrutiny due to its novelty.
