Best Peptides for Better Sleep
Sleep peptides restore deep slow-wave sleep architecture through various mechanisms — from direct delta-wave induction (DSIP) to GH secretagogues that enhance sleep-dependent recovery (Ipamorelin, MK-677). Better sleep means better recovery, cognition, and longevity.

Showing 6 peptides ranked by popularity and research evidence
MK-677
ResearchGrowth HormoneAn oral, non-peptide growth hormone secretagogue that elevates GH and IGF-1 levels for up to 24 hours. Popular for its convenience and effects on sleep, bone density, and body composition.
Sermorelin
ResearchGrowth HormoneA bioidentical analog of growth hormone-releasing hormone (GHRH). The bedrock of clinical anti-aging endocrinology, prescribed to safely restore youthful IGF-1 levels and improve sleep.
Epitalon
ResearchAnti-AgingA synthetic tetrapeptide derived from the bovine pineal gland, sitting at the apex of life-extension bioscience. Studied for its ability to activate telomerase and reset the biological clock.
DSIP
ResearchSleepA naturally occurring nonapeptide that resets circadian rhythm and forces the brain into deep slow-wave (delta) sleep. Not a sedative but a master sleep regulator.
Pinealon
ResearchBioregulatorA Khavinson tripeptide bioregulator for brain cortex modulation, circadian rhythm restoration, and neuroprotection against oxidative aging.
Endoluten
ResearchBioregulatorThe crown jewel of the Khavinson Cytomax line — the natural pineal extract predecessor to Epitalon for circadian and longevity restoration.
