Side-by-side comparison
| Exenatide | Tesamorelin | |
|---|---|---|
| Category | Weight Management & Metabolic | Performance & Growth |
| Regulatory status (US) | FDA approved | FDA approved |
| Typical dosage | 5–10 mcg (Byetta) or 2 mg (Bydureon/Bydureon BCise) | 2 mg |
| Frequency | Twice daily (Byetta) or once weekly (Bydureon) | daily |
| Reported benefits | Glycemic control (HbA1c reduction 0.8–1.9 percentage points), modest body weight reduction (2–4 kg), low intrinsic hypoglycemia risk, modest systolic blood pressure reduction, cardiovascular non-inferiority established in EXSCEL | Visceral fat reduction, improved body composition, GH release |
| Reported side effects | Nausea, vomiting, diarrhea, injection site reactions, hypoglycemia (when co-administered with sulfonylureas), rare acute pancreatitis, rare acute kidney injury | Joint pain, peripheral edema |
Key differences
Primary use. Exenatide is categorised under Weight Management & Metabolic, while Tesamorelin falls under Performance & Growth. Their differing categories mean they are usually chosen for different goals rather than as direct substitutes.
Regulatory status. Exenatide: FDA-approved. Tesamorelin: FDA-approved.
Dosing. Exenatide is typically dosed at 5–10 mcg (Byetta) or 2 mg (Bydureon/Bydureon BCise) (Twice daily (Byetta) or once weekly (Bydureon)). Tesamorelin is typically dosed at 2 mg (daily).
Can you stack them?
Some protocols combine peptides, but stacking Exenatide and Tesamorelin has not been validated for safety or efficacy in controlled trials. Combining compounds can change their effects and risks. Nothing here is medical advice — consult a qualified healthcare provider before starting or combining any protocol.
