- Molecular Structure
- Semax + adamantyl moiety (defined)
- Variable. May be N-acetyl Semax, generic enhanced Semax, or other
- Request third-party MS verification before use
- Lipophilicity
- High (log P increased by ~2.0 units)
- Variable depending on formulation
- Adamantyl modification delivers measurably higher BBB penetration
- CNS Bioavailability (intranasal)
- 3.5–4.2× higher than unmodified Semax
- Dependent on specific formulation
- Semax-Adamantyl provides predictable, dose-proportional CNS delivery
- Half-Life (plasma)
- 140–180 minutes
- Variable (60–120 minutes typical)
- Longer half-life allows twice-daily dosing in most protocols
- Onset of Effect (intranasal)
- 20–30 minutes to peak CNS concentration
- 30–60 minutes (N-acetyl), 45–90 minutes (standard Semax)
- Use Semax-Adamantyl for acute cognitive tasks requiring rapid onset
- Recommended Use Case
- Acute cognitive enhancement, neuroprotection studies with rapid endpoints
- Chronic administration, steady-state cognitive support
- Match compound to study timeline. Adamantyl for short-term, acetylated for long-term
