    Summary · context
    The removal of the frog skin supporting layers accelerated the onset of the reactions to oxytocin and 8-bromo-cyclic AMP (8-Br-cAMP), which, however, remained slower than the onset in the urinary bladder.
    Summary · context
    The onset and offset of the hydrosmotic responses elicited by different agonists in frog urinary bladder, frog skin and isolated frog skin epithelium were studied and compared.

Studies that did not test the peptide alone3

In this study, Oxytocin 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 Oxytocin.
