About DSIP
DSIP (delta sleep-inducing peptide) is a naturally occurring nonapeptide first identified for its association with slow-wave sleep activity in the brain. Its precise receptor targets remain under investigation, and it is studied as a neuromodulatory tool in sleep and stress-related research models.
Researchers examine DSIP in models of sleep architecture, circadian regulation, stress and neuroendocrine response, and neuroprotective signaling. It is supplied as a lyophilized powder intended for reconstitution in suitable solvent under controlled laboratory conditions, tested to ≥98% purity with a certificate of analysis available on request. This material is sold strictly for research use only and not for human consumption.
