Best-selling DSIP 99% pure peptide raw material for improving sleep. Discounted price. In stock. CAS number: 62568-57-4

DSIP (Delta-Sleep-Inducing Peptide, δ-sleep-inducing peptide) is a naturally occurring neuropeptide that was initially discovered for its ability to induce δ-wave (slow-wave) sleep. Its main functions include: promoting sleep (inducing slow-wave sleep), providing pain relief (by activating the descending monoaminergic pathway and indirectly releasing endorphins), and regulating biological rhythms (influencing the generation of circadian rhythms and the activity of the pineal gland enzymes).

Promote sleep: Mainly induce slow-wave (delta wave) sleep.
Analgesia: It produces analgesic effects indirectly by activating the descending pathways.
Antisstress: Reducing the release of corticosterone.
Regulating biological rhythms: Influencing the generation of circadian rhythms and the activity of pineal gland enzymes.
