Best Peptides for Sleep & Recovery
Peptides researched for sleep quality, circadian rhythm support, and overnight recovery.
Understanding Sleep Improvement Peptides
Sleep peptides target various pathways to improve sleep quality and recovery. DSIP (Delta Sleep-Inducing Peptide) was among the first peptides identified for sleep regulation. GH secretagogues like Ipamorelin are often taken before bed to enhance the natural growth hormone surge during sleep. Epitalon may support melatonin production through pineal gland effects. Sleep peptides can support the restorative processes that occur during deep sleep phases.
Key Considerations
- DSIP has limited modern clinical research despite early promise
- GH secretagogues may improve sleep quality through enhanced deep sleep phases
- Timing is crucial - most sleep peptides are taken 30-60 minutes before bed
- Sleep hygiene fundamentals should not be neglected
- Some peptides may cause vivid dreams or affect sleep architecture
FDA Approved Options (1)
Research Peptides (9)
These peptides are being researched but are not FDA approved. They should only be considered for research purposes or under medical supervision.
DSIP
Clinical TrialsA neuropeptide that promotes deep delta wave sleep. First isolated from rabbit brains in 1977. Used for sleep optimization and stress reduction.
Ipamorelin
Clinical TrialsA selective growth hormone secretagogue that stimulates GH release without significantly affecting cortisol or prolactin. Considered one of the safest GHRPs.
CJC-1295
Clinical TrialsA synthetic analog of growth hormone-releasing hormone (GHRH) that stimulates GH release from the pituitary. Often combined with a GHRP like Ipamorelin for synergistic effects.
GHRP-6
Clinical TrialsOne of the first synthetic GH secretagogues developed. Strongly stimulates GH release and significantly increases appetite through ghrelin receptor activation.
GHRP-2
Clinical TrialsA synthetic hexapeptide that potently stimulates GH release. More potent than GHRP-6 with less appetite stimulation, but still elevates cortisol and prolactin.
Sermorelin
PreclinicalA truncated analog of natural GHRH containing the first 29 amino acids. Previously FDA-approved for pediatric GH deficiency, now used off-label for adult hormone optimization.
MK-677
Clinical TrialsAn orally active growth hormone secretagogue that mimics ghrelin. Not a peptide technically, but frequently discussed alongside GH peptides due to similar effects.
Hexarelin
Clinical TrialsA synthetic hexapeptide GH secretagogue with the strongest GH-releasing effect among GHRPs. Also has notable cardioprotective properties independent of GH release.
CJC-1295 DAC
Clinical TrialsA long-acting GHRH analog with Drug Affinity Complex for extended half-life. Provides sustained GH elevation for days with single injection.
Frequently Asked Questions
What peptides help with sleep?
DSIP (Delta Sleep-Inducing Peptide) was specifically identified for sleep regulation. GH secretagogues like Ipamorelin taken before bed can enhance growth hormone release during sleep. Epithalon may support melatonin production. Selank has anxiolytic effects that may indirectly improve sleep.
How does DSIP work?
DSIP (Delta Sleep-Inducing Peptide) was originally isolated from rabbit brain tissue during induced sleep. It appears to modulate sleep architecture, potentially increasing delta wave sleep. However, research has been inconsistent and limited in recent decades.
Do GH peptides improve sleep?
GH secretagogues may improve sleep quality by enhancing the natural growth hormone surge that occurs during deep sleep. Many users report deeper, more restorative sleep when taking peptides like Ipamorelin before bed, though controlled studies are limited.
