Studies that did not test the peptide alone1

In this study, Bremelanotide (PT-141) 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 Bremelanotide (PT-141).

  1. 01HumanNot a test of Bremelanotide (PT-141) aloneSystematic reviewEfficacy outcome

    In women with hypoactive sexual desire disorder, pooled medication trials (testosterone, flibanserin and bremelanotide) had a mean Cohen d effect size of 1.0 (SD 0.34), similar to CBT and MMT at 1.0.

    In plain wordsIn women with low sexual desire, several drugs pooled together showed a large effect, similar to talking therapies. Not a bremelanotide-only result.
