A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Exenatide
Exenatide was the first GLP-1 receptor agonist approved in the US, derived from a compound found in Gila monster saliva. Available as Byetta (twice daily) and Bydureon (once weekly extended-release).

Teriparatide (Forteo) is recombinant human parathyroid hormone (1-34), FDA-approved for osteoporosis treatment. It's unique among osteoporosis drugs in that it stimulates new bone formation.
Full details →Side-by-Side Comparison
| Aspect | Exenatide | Teriparatide |
|---|---|---|
| Mechanism | Synthetic version of exendin-4, which activates GLP-1 receptors to enhance glucose-dependent insulin secretion, suppress glucagon, slow gastric emptying, and promote satiety. | Intermittent PTH exposure paradoxically stimulates osteoblasts more than osteoclasts, resulting in net bone formation. Continuous exposure would cause bone loss, but pulsatile dosing builds bone. |
| Typical Dosage | Byetta: 5mcg twice daily for 1 month, then 10mcg twice daily. Bydureon: 2mg subcutaneously once weekly. | 20mcg subcutaneously once daily. Maximum treatment duration of 2 years due to theoretical osteosarcoma risk from rat studies. |
| Administration | Byetta: Inject within 60 minutes before morning and evening meals. Bydureon: Any time of day, with or without meals. Do not mix with insulin in same syringe. | Subcutaneous injection in thigh or abdomen once daily. Delivered via multi-dose pen. Should sit or lie down after injection due to orthostatic hypotension risk. |
| Side Effects | Nausea (especially initially), vomiting, diarrhea, dizziness, headache, and injection site reactions (particularly with Bydureon). | Orthostatic hypotension, leg cramps, nausea, dizziness, headache, and injection site reactions. Transient hypercalcemia possible. |
