Peptides AcademySleep & Circadian Peptides
Peptides with proposed effects on sleep architecture or circadian regulation. DSIP (delta sleep-inducing peptide) is the historical flagship; modern evidence is sparse.
Sleep Peptides (2)
Cortistatin
Research-Grade
A neuropeptide structurally related to somatostatin that promotes slow-wave sleep, modulates cortical activity, and exerts potent anti-inflammatory effects through both somatostatin-shared and cortistatin-specific receptor pathways.
DSIP (Delta Sleep-Inducing Peptide)
Research-Grade
A 9-amino-acid neuropeptide isolated from the rabbit brain, investigated for delta-wave sleep promotion and stress-axis modulation.
