Best Peptides for Sleep
Sleep peptides and protocols ranked by research depth (DSIP leads), each routed to our deep guide so you can read the underlying studies.
How We Ranked These
This is a routing page, not a prescription. We ranked these sleep peptides and protocols by how directly the research connects to sleep, with DSIP as the headliner. Behavioral basics come first, so two of our picks are playbooks, not compounds. Each links to a deep guide. Start with the goal hub: Sleep goals.
Fundamentals before peptides: Light, timing, temperature, and caffeine timing are the basics to fix first. For chronic insomnia in adults, cognitive behavioral therapy (CBT-I) is the recommended first treatment (ACP guideline, PMID 27136449). Peptides are research compounds and should never replace sleep hygiene or medical evaluation of a sleep disorder. This page summarizes the research. It is not medical advice, so talk to a clinician before using any compound.
Sleep Peptides Ranked
DSIP (Delta Sleep-Inducing Peptide)
The headliner, and the only compound here named for sleep itself. DSIP is the peptide most directly studied in the context of sleep regulation. Human evidence is limited and older, so treat it as a research compound, but it's the obvious starting point for the category.
Read the DSIP guide →Sleep Optimization (Protocol)
Not a compound: the first thing to fix. Our sleep-optimization guide covers light exposure, timing, temperature, and caffeine. Fix these before considering any peptide.
Read the Sleep Optimization guide →Bryan Johnson Sleep Protocol
A worked example of an aggressive, data-driven sleep routine. Useful as a template for what a maximalist protocol looks like (consistent timing, environment control, measurement), even if you adopt only the parts that fit your life.
Read the Bryan Johnson Sleep guide →Epitalon
Epitalon is studied for circadian regulation via the pineal axis, which is the sleep-relevant angle. Its primary framing is longevity rather than sleep, so the sleep-specific evidence is indirect; it ranks last here for that reason.

✅ What We Know
- DSIP is the peptide most directly studied for sleep regulation
- For chronic insomnia in adults, CBT-I is the recommended first treatment (ACP, PMID 27136449)
- Epitalon is studied for circadian regulation via the pineal axis
- The Bryan Johnson playbook is one person's routine, not a clinical trial
⚠️ What We Don't
- Human DSIP evidence is limited and older
- Optimal dosing and timing for sleep peptides aren't established
- Epitalon's sleep-specific benefit is indirect, not proven
- No sleep peptide here is an FDA-approved sleep aid
- Peptides do not replace evaluation of an underlying sleep disorder
