- DSIP
- GABAergic modulation, hypothalamic regulation
- 7–14 days for objective markers, 18–21 days for subjective quality
- 18–35% increase in Stage 3 NREM by week 4
- Minimal. 8-minute reduction only after day 21
- Effects persist 3–7 days post-cessation
- Best for architecture repair, not sleep initiation
- Epitalon
- Telomerase activation, melatonin regulation
- 10–21 days
- Indirect. Improves via circadian normalisation
- 12–18 minutes reduction by day 14
- Unknown. Likely sustained with periodic dosing
- Broader longevity focus, sleep is secondary benefit
- Selank
- Anxiolytic via BDNF upregulation
- 3–7 days
- Minimal direct effect on SWS
- 15–22 minutes reduction by day 5
- 5–10 days post-cessation
- Better for anxiety-driven sleep onset issues
- Semax
- Nootropic, monoamine modulation
- 1–3 days
- None. May reduce REM slightly
- No effect or worsening in some users
- 2–4 days
- Not a sleep peptide. Can disrupt architecture
- The table underscores why setting the right expectation for DSIP deep sleep results timeline expect matters: if you need faster sleep onset, Selank's anxiolytic mechanism works within days. If your problem is fragmented deep sleep (frequent awakenings, non-restorative sleep despite 7–8 hours), DSIP's architecture-rebuilding mechanism is superior but demands patience. Combining peptides accelerates neither. The mechanisms don't synergise for sleep outcomes. Our experience with client research protocols shows better adherence when researchers understand DSIP's unique timeline upfront rather than abandoning it prematurely because 'it didn't work after five days.'
