Other Peptides for Weight Loss
These peptides are also researched for weight loss.
Semaglutide
FDAA GLP-1 receptor agonist with multiple FDA approvals including weight loss, T2D, CV risk reduction, and kidney protection. Wegovy pill approved Dec 2025 as first oral GLP-1 for weight loss.
Tirzepatide
FDAA dual GIP/GLP-1 receptor agonist representing the next generation of incretin-based therapies. Shows superior weight loss compared to semaglutide in head-to-head trials. First medication approved for obstructive sleep apnea.
Retatrutide
Clinical TrialsA triple agonist targeting GLP-1, GIP, and glucagon receptors. Phase 3 trials show up to 28.7% weight loss (71 lbs average), the highest of any obesity drug. Expected FDA approval late 2026 to early 2027.
CagriSema
Clinical TrialsA combination of semaglutide and cagrilintide (amylin analog). The most effective weight loss drug candidate, showing 22.7% body weight reduction in Phase 3 trials - superior to any single-agent GLP-1.
