Delta Sleep-Inducing Peptide (DSIP) is a neuropeptide that was discovered in the 1970s during research on sleep. It was initially isolated from the cerebral venous blood of rabbits in an induced state of sleep and was shown to induce delta-wave sleep in rabbits when administered intravenously.

DSIP is of interest to the scientific community due to its unique properties and potential applications. It is associated with modulating sleep patterns, stress response, and endocrine regulation. The exact mechanism of action of DSIP is not fully understood, but it is believed to play a role in the regulation of sleep, body temperature, and hormonal balance.

It has been studied for its possible therapeutic benefits, such as treatment for insomnia, stress relief, and as an adjunct therapy for various conditions that are influenced by stress or disrupted sleep patterns. There’s also some research into DSIP’s potential in neuroprotective, anticonvulsive, and antinociceptive (pain reduction) effects.

This peptide comes in lyophilized vials.
