Results from this study2

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

Natural levels measured2

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

    In rats under acute emotional stress, natural DSIP content in blood and hypothalamus was higher in stress-resistant Wistar rats than in stress-predisposed August rats.

    In plain wordsIn rats, the body's own DSIP levels were higher in the stress-resistant Wistar line than in the August line.

    Summary
    It was found that the contents of these peptides in Wistar-rats, which are more resistant to emotional stress, were higher compared with the August-rats, which are more predisposed to emotional stress.
