Studies that did not test the peptide alone1

In this study, Delta sleep-inducing peptide (DSIP) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Delta sleep-inducing peptide (DSIP).

  1. 03AnimalNot a test of Delta sleep-inducing peptide (DSIP) aloneAnimal study (in vivo)Efficacy outcome

    In normal rabbits, delta-sleep-inducing peptide and its 10 analogues together increased the total amount of slow oscillations in the EEG and shifted the spectrum toward the long-wave area.

    In plain wordsIn rabbits, DSIP and its 10 DSIP-like compounds increased slow brain waves.
