Exenatide vs MOTS-c

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).

Side-by-Side Comparison

Aspect	Exenatide	MOTS-c
Dose Range	5 mcg–10 mcg	5 mg–10 mg
Frequency	2x daily	Less than daily
Cycle Length	8–24 weeks	8–12 weeks
Route	subcutaneous	subcutaneous
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.	Activates AMPK pathway, enhances glucose uptake in skeletal muscle, improves insulin sensitivity, and regulates mitochondrial function. Acts as a metabolic hormone affecting whole-body energy homeostasis.
Typical Dosage	Byetta: 5mcg twice daily for 1 month, then 10mcg twice daily. Bydureon: 2mg subcutaneously once weekly.	Research protocols typically use 5-10mg administered subcutaneously several times per week. Optimal dosing not yet established.
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. Often combined with exercise protocols as it enhances exercise capacity and metabolic adaptation.
Side Effects	Nausea (especially initially), vomiting, diarrhea, dizziness, headache, and injection site reactions (particularly with Bydureon).	Limited human data. Animal studies show good tolerability. May affect energy levels and exercise performance.
