| Aspect | MOTS-c | Semax |
|---|---|---|
| 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. | Enhances BDNF expression, modulates dopamine and serotonin systems, and provides neuroprotective effects. Increases attention, memory formation, and learning. |
| Typical Dosage | Research protocols typically use 5-10mg administered subcutaneously several times per week. Optimal dosing not yet established. | Intranasal: 200-600mcg 2-3 times daily. Higher doses (up to 1mg) used in clinical settings for stroke recovery. |
| Administration | Subcutaneous injection. Often combined with exercise protocols as it enhances exercise capacity and metabolic adaptation. | Primarily administered intranasally. N-Acetyl Semax Amidate (NASA) is a modified version with enhanced stability and potency. |
| Side Effects | Limited human data. Animal studies show good tolerability. May affect energy levels and exercise performance. | Generally well-tolerated. May cause mild irritability or hair shedding in some users. |
