Liraglutide vs SS-31 (Elamipretide)
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Liraglutide
Liraglutide is a GLP-1 receptor agonist FDA-approved as Victoza for type 2 diabetes and Saxenda for chronic weight management. It was one of the first daily GLP-1 agonists and paved the way for newer weekly options like semaglutide.
Full details →SS-31 (Elamipretide)
SS-31, also known as Elamipretide or Bendavia, is a mitochondria-targeted tetrapeptide. It has been studied extensively for mitochondrial diseases, heart failure, and age-related decline in mitochondrial function.
Full details →Side-by-Side Comparison
| Aspect | Liraglutide | SS-31 (Elamipretide) |
|---|---|---|
| Mechanism | Binds to and activates GLP-1 receptors, stimulating insulin secretion in a glucose-dependent manner, suppressing glucagon release, slowing gastric emptying, and reducing appetite through central nervous system effects. | Concentrates in the inner mitochondrial membrane where it binds to cardiolipin, stabilizing electron transport chain function, reducing reactive oxygen species, and improving ATP production efficiency. |
| Typical Dosage | Saxenda (weight loss): Start 0.6mg daily, increase weekly by 0.6mg to maintenance dose of 3mg daily. Victoza (diabetes): 0.6mg to 1.8mg daily. | Clinical trials have used IV infusions of 0.25mg/kg for acute conditions. Subcutaneous dosing protocols for research use typically range from 1-5mg daily. |
| Administration | Subcutaneous injection once daily at any time, independent of meals. Rotate injection sites. Can be used with oral diabetes medications. | Can be administered IV or subcutaneously. Most clinical research has used IV administration for cardiac conditions. |
| Side Effects | Nausea, vomiting, diarrhea, constipation, headache, decreased appetite. GI effects typically diminish over time with continued use. | Generally well-tolerated. Clinical trials reported injection site reactions and occasional headache. |
