- Intranasal
- Moderate-Good
- Yes (olfactory/trigeminal)
- Low-Moderate
- Yes — most common
- Subcutaneous
- Low (BBB limiting)
- Partial (slow, limited)
- Low
- Yes — used in some studies
- Intraperitoneal
- Low-Moderate (BBB limiting)
- Partial
- Occasionally
- Intravenous
- Low (rapid degradation)
- No (requires BBB crossing)
- High
- Rare
- Intracerebroventricular
- High (direct CNS)
- N/A (direct injection)
- Very High
- Rare, specialized studies
- For the vast majority of Semax preclinical neuroscience research, intranasal delivery offers the best balance of CNS delivery efficiency and technical accessibility.
