Cortexin vs MOTS-c
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Cortexin
Cortexin is a polypeptide complex derived from pig brain cortex, used clinically in Russia and Eastern Europe for neurological conditions including stroke recovery, traumatic brain injury, and cognitive decline.
Full details →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 →Side-by-Side Comparison
| Aspect | Cortexin | MOTS-c |
|---|---|---|
| Mechanism | Contains a mixture of neuropeptides and amino acids that support neuronal metabolism, provide neuroprotection, and enhance synaptic transmission. Specific mechanisms not fully characterized. | 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 | Clinical protocols: 10mg intramuscularly once daily for 10-20 days. May be repeated after 3-6 month interval. | Research protocols typically use 5-10mg administered subcutaneously several times per week. Optimal dosing not yet established. |
| Administration | Intramuscular injection. Comes as lyophilized powder requiring reconstitution. Treatment given in courses rather than continuously. | Subcutaneous injection. Often combined with exercise protocols as it enhances exercise capacity and metabolic adaptation. |
| Side Effects | Generally well-tolerated. May cause injection site reactions or mild allergic responses in sensitive individuals. | Limited human data. Animal studies show good tolerability. May affect energy levels and exercise performance. |
