Studies that did not test the peptide alone4

In this study, Kisspeptin-10 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 Kisspeptin-10.

    Summary
    In addition, dual-label in situ hybridization in the hypothalamus of female rats showed that Kiss1r is expressed in the periventricular nucleus of the hypothalamus (Pe) and arcuate nucleus of the hypothalamus (ARC) but not in tyrosine hydroxylase (Th)-expressing neurons.

    Summary
    Kisspeptin also has affinity for the neuropeptide FF receptor 1 (Npffr1), which was expressed in the majority of Pe dopaminergic neurons but only in a low proportion of TIDA neurons in the ARC.
