Results from this study2

No result from this study comes from a test of the peptide.

Studies that did not test the peptide alone2

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. 01AnimalNot a test of Delta sleep-inducing peptide (DSIP) aloneAnimal study (in vivo)Mechanism

    In rats, pretreatment with alpha MPT and/or L-tryptophan clearly potentiated the sleep signs that followed DSIP.

    In plain wordsIn rats, pretreatment with other drugs clearly strengthened the sleep signs seen after DSIP.
