- 10–14 days
- 100–300mcg nightly
- Acute sleep latency reduction, subjective quality improvement
- Minimal. Circadian rhythm adjustment requires sustained administration
- Useful for preliminary assessment of peptide tolerance and timing optimisation before committing to extended protocols
- 20–30 days
- 200–500mcg nightly
- Delta wave amplification, slow-wave sleep percentage increase, REM architecture modulation
- Moderate to strong. Most subjects show cumulative entrainment after 14–21 consecutive nights
- Standard research duration for polysomnography-validated sleep architecture studies. Long enough to measure objective changes without risking peptide degradation in reconstituted solution
- 40+ days
- 300–500mcg nightly
- Long-term circadian phase shifting, chronic insomnia protocols
- Strong. Sustained administration produces stable phase advance or delay depending on timing
- Requires mid-cycle vial replacement due to 28-day reconstituted stability limit. Logistically complex but documented in extended research settings
