Quick verdict

Preclinical neuroprotection research is interesting. Human clinical data are absent.

Reality check

What this isn't

  • Not approved for human use — research-only context
  • No regulator has approved human use
  • Evidence base is early — long-term data limited
  • Side-effect profile not fully characterised
  • Educational only — not medical advice
