Exenatide vs Epitalon
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).
Full details →Epitalon
Epitalon (Epithalon) is a synthetic tetrapeptide based on the natural peptide epithalamin, produced by the pineal gland. It is primarily studied for its effects on telomerase activation.
Full details →Side-by-Side Comparison
| Aspect | Exenatide | Epitalon |
|---|---|---|
| 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. | Stimulates telomerase production, which can lengthen telomeres on DNA strands. May also regulate melatonin production and circadian rhythms. |
| Typical Dosage | Byetta: 5mcg twice daily for 1 month, then 10mcg twice daily. Bydureon: 2mg subcutaneously once weekly. | Typical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year. |
| 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 or intramuscular injection. Usually administered in cycles rather than continuously. |
| Side Effects | Nausea (especially initially), vomiting, diarrhea, dizziness, headache, and injection site reactions (particularly with Bydureon). | Generally well-tolerated. May affect sleep patterns initially. |
