Best Peptides for Sleep Quality
Quality sleep is foundational to recovery, cognitive function, and overall health. While behavioral and environmental factors are the first-line approach to sleep improvement, researchers have also investigated peptides that may influence sleep architecture and onset.
DSIP (Delta Sleep-Inducing Peptide) was one of the earliest peptides studied specifically for sleep. Selank may reduce anxiety-related sleep disturbances, and MK-677's effect on GH pulsatility has been studied for its influence on sleep quality and REM duration.
Recommended Peptides
DSIP
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide first identified in 1974 from rabbit thalamic venous blood. It is named for its ability to induce delta (slow-wave) sleep activity in animal models and is studied for sleep quality, stress response, and neuroendocrine modulation.
Read full profile >Selank
Selank is a synthetic heptapeptide analog of the immunomodulatory peptide tuftsin, developed in Russia. It is registered as a drug in Russia for anxiety disorders and is studied for its anxiolytic, nootropic, and immunomodulatory properties with a favorable side effect profile.
Read full profile >MK-677
MK-677 (Ibutamoren) is an orally active, non-peptide growth hormone secretagogue that mimics ghrelin and stimulates GH and IGF-1 release. Unlike injectable GH peptides, it is taken orally and provides sustained GH elevation. It is studied for muscle growth, bone density, and metabolic effects.
