Results from this study5

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

Studies that did not test the peptide alone5

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).
