  • 0.25mg subcutaneous
  • Subcutaneous
  • 90 minutes
  • Minimal effect in Western replication studies; early Soviet trials reported benefit but peptide purity questioned
  • Insufficient dose for most subjects. Trial only if extreme peptide sensitivity suspected
  • 0.5mg subcutaneous
  • 60–90 minutes
  • Sleep onset latency reduced by 15–20 minutes; inconsistent slow-wave sleep increase
  • Effective starting dose for initial protocol design; escalate if no response after 5–7 days
  • 1mg subcutaneous
  • Sleep onset latency reduced by 25–30 minutes; SWS duration increased 20–25 minutes
  • Standard research dose. Most consistent outcomes across published studies
  • 2mg subcutaneous
  • SWS duration increased 28–32 minutes; higher probability of vivid dreams and next-morning grogginess
  • Reserve for subjects with documented cortisol dysregulation or chronic stress insomnia; marginal benefit over 1mg
  • 1mg intranasal
  • Intranasal
  • 30–60 minutes
  • Highly variable absorption; 40–60% inconsistency between subjects
  • Not recommended. Subcutaneous delivery far more reliable
