Exenatide vs Cerebrolysin
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 →Cerebrolysin
Cerebrolysin is a mixture of low-molecular-weight neuropeptides and free amino acids derived from purified pig brain proteins. It is approved in many countries for stroke, traumatic brain injury, and dementia.
Full details →Side-by-Side Comparison
| Aspect | Exenatide | Cerebrolysin |
|---|---|---|
| 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. | Contains multiple neurotrophic factors that promote neuroplasticity, reduce neuronal apoptosis, and support synaptic function. Has both neurotrophic and neuroprotective properties. |
| Typical Dosage | Byetta: 5mcg twice daily for 1 month, then 10mcg twice daily. Bydureon: 2mg subcutaneously once weekly. | Clinical dosing: 10-30ml IV daily for acute conditions. Research use: 5-10ml IM daily for cognitive enhancement. Treatment courses typically last 10-20 days. |
| 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. | Administered via intramuscular or intravenous injection. IV administration is typically used in clinical settings. IM can be used for research purposes. |
| Side Effects | Nausea (especially initially), vomiting, diarrhea, dizziness, headache, and injection site reactions (particularly with Bydureon). | Generally well-tolerated. May cause dizziness, headache, sweating, or injection site reactions. Rare cases of agitation or confusion. |
