- DSIP
- Amplifies delta-wave oscillations in thalamus/cortex during NREM Stage 3
- Increases slow-wave sleep duration by 18–34 min/night; no REM suppression
- 50–150mcg subcutaneous 30–60 min before bed
- Gradual; noticeable effects week 2, peak week 3–4
- Gold standard for slow-wave sleep restoration. No sedation, no tolerance, objective polysomnography improvements
- Epithalon
- Activates telomerase in pineal gland; restores endogenous melatonin synthesis
- Improves sleep latency and efficiency by normalizing circadian rhythm
- 10mg subcutaneous in 10-day cycles (e.g., 10 days on, 20 days off)
- Cumulative; benefits emerge over 4–6 weeks of cycling
- Best for age-related circadian decline. Addresses pineal calcification without negative feedback from exogenous melatonin
- Pinealon
- Reduces neuroinflammation (IL-6, TNF-alpha) in pineal gland
- Restores circadian light sensitivity; reduces sleep onset latency by 15–20 min
- 20mg subcutaneous in 10-day cycles, often stacked with epithalon
- 2–3 weeks for noticeable sleep onset improvements
- Critical for chronic stress-related circadian disruption. Corrects inflammatory interference with circadian signaling
