MOTS-c vs Liraglutide
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
MOTS-c
MOTS-c (Mitochondrial Open Reading Frame of the Twelve S rRNA type-c) is a mitochondrial-derived peptide that plays a key role in metabolic regulation and has emerged as a significant longevity research target.
Full details →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.

| Aspect | MOTS-c | Liraglutide |
|---|---|---|
| Mechanism | 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. | 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. |
| Typical Dosage | Research protocols typically use 5-10mg administered subcutaneously several times per week. Optimal dosing not yet established. | 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. |
| Administration | Subcutaneous injection. Often combined with exercise protocols as it enhances exercise capacity and metabolic adaptation. | Subcutaneous injection once daily at any time, independent of meals. Rotate injection sites. Can be used with oral diabetes medications. |
| Side Effects | Limited human data. Animal studies show good tolerability. May affect energy levels and exercise performance. | Nausea, vomiting, diarrhea, constipation, headache, decreased appetite. GI effects typically diminish over time with continued use. |
