Body Composition

Body Composition

Semaglutide (GLP-1)

GLP-1 receptor agonist widely studied for appetite regulation, blood sugar control, and body composition.

  • Appetite regulation in clinical trials
  • Glycemic-control research
  • Body-weight reduction in STEP trials
Top RatedBody Composition

Tirzepatide

Dual GIP/GLP-1 receptor agonist studied for synergistic effects on insulin secretion, fat metabolism, and appetite suppression — showing a greater magnitude of weight loss than semaglutide in head-to-head trials.

  • Dual GIP/GLP-1 receptor agonism
  • SURMOUNT trials: 20–22% body-weight reduction over 72 weeks
  • ~20% greater weight loss than semaglutide in SURMOUNT-5
Phase 3Body Composition

Retatrutide

Triple receptor agonist targeting GLP-1, GIP, and glucagon receptors. Phase 3 trials recorded up to 24.2% body weight reduction — the highest of any compound in its class.

  • Triple-receptor agonism (GLP-1/GIP/glucagon)
  • Appetite research in Phase 2 trials
  • Body-weight reduction in TRIUMPH-1 data
Body Composition

Cagrilintide

Long-acting amylin analog studied for appetite suppression and satiety signaling. Most researched in combination with semaglutide (as CagriSema), where Phase 3 data showed greater weight reduction than either compound alone.

  • Amylin/calcitonin receptor agonism
  • Satiety-signaling research distinct from GLP-1 pathway
  • Studied alongside semaglutide in Phase 3 combination trials
Body Composition

Tesamorelin

Synthetic GHRH analog that stimulates endogenous growth hormone release. Studied for visceral fat reduction, body composition, and metabolic health.

  • Visceral-fat reduction in RCTs
  • GH-stimulation research
  • Body-composition studies
Body Composition

AOD-9604

Synthetic fragment of human growth hormone (hGH 176-191) studied for its role in fat metabolism and lipolysis without affecting blood sugar or IGF-1 levels.

  • Lipolysis research (hGH 176-191)
  • Fat-metabolism study models
  • No IGF-1 effect in studies
