Other Peptides for Type 2 Diabetes
These peptides are also researched for type 2 diabetes.
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.
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.
Orforglipron
FDAAn oral non-peptide GLP-1 receptor agonist. FDA approved April 1, 2026 under the brand name Foundayo — the first daily oral GLP-1 pill for weight loss. Distribution began April 6, 2026. FDA subsequently requested additional post-approval safety data.
Liraglutide
FDAAn FDA-approved GLP-1 receptor agonist for type 2 diabetes and chronic weight management. The predecessor to semaglutide with daily dosing.
