Endogenous sleep signal, not a sedative compound.
DSIP (Delta Sleep Inducing Peptide) is a naturally occurring nonapeptide first identified in cerebral venous blood — studied for its role in promoting slow-wave sleep, modulating the hypothalamic-pituitary-adrenal axis, and normalizing sleep architecture in stress and insomnia models.
It is not FDA-approved for medical use. Natura ships it as a batch-verified research pen so you can dial a consistent dose and read the lab paperwork before you open the box.
