- 5 days
- Weekly
- Dual GIP/GLP-1 agonist. Appetite suppression + insulin sensitization
- 40–50% GI events during titration
- Highest documented efficacy for 50+ lb targets. Dual mechanism offsets metabolic adaptation
- Semaglutide 2.4mg
- 14.9%
- 37 lbs
- 7 days
- GLP-1 agonist. Delayed gastric emptying, reduced ghrelin
- 30–35% GI events during titration
- Strong efficacy with better tolerability than tirzepatide. Proven long-term safety data
- Survodutide (Phase 3)
- 12.8% (Phase 2)
- 32 lbs
- Not disclosed
- Weekly (expected)
- GLP-1/glucagon dual agonist. Appetite + thermogenesis
- Not fully characterized
- Promising but not FDA-approved. Glucagon component may address NEAT suppression
- Liraglutide 3.0mg
- 8.0%
- 20 lbs
- 13 hours
- Daily
- GLP-1 agonist. Appetite suppression only
- 28–32% GI events
- Effective but requires daily injection. Insufficient for 50 lb target without extended duration
- Ipamorelin + CJC-1295
- 2–3%
- 5–8 lbs
- 30 min (ipamorelin)
- Daily to 2x/week
- GH secretagogue. Lipolysis without appetite suppression
- Minimal. Occasional injection site reaction
- Adjunct only. Does not create caloric deficit independently
- MK-677 (Ibutamoren)
- 1–2%
- 2.5–5 lbs
- 24 hours
- Daily (oral)
- Ghrelin mimetic. Elevates GH but increases appetite
- Increased hunger, water retention
- Counterproductive for weight loss. Elevated ghrelin negates lipolytic benefit
