- DSIP
- Delta-opioid receptor agonist. Reduces cortisol-driven wakefulness
- 60–90 minutes before sleep
- 100–500 mcg subcutaneous
- Sleep-onset insomnia, stress-related waking
- Works fastest but requires consistent timing. Miss the window and receptor occupancy drops below therapeutic threshold
- Epitalon
- Telomerase activation in pineal gland. Restores melatonin synthesis capacity
- Morning administration for next-night effect
- 5–10 mg IM daily for 10 days, cycled every 4–6 months
- Age-related sleep degradation, early-morning waking
- Long-term circadian restoration, not acute sedation. Effects build over 7–10 days
- MK 677
- Growth hormone secretagogue. Increases slow-wave sleep duration
- 60 minutes before sleep
- 12.5–25 mg oral
- Shallow sleep, frequent waking, insufficient deep sleep
- Amplifies natural GH pulse during first sleep cycle. Most effective for sleep maintenance, not onset
- Thymalin
- Immune modulation. Reduces inflammatory cytokines that fragment sleep
- Every other day, time-independent
- 5–10 mg IM every 48 hours for 10 doses
- Immune-mediated sleep disruption, chronic inflammation
- Targets inflammatory sleep fragmentation specifically. Won't help non-immune sleep issues
