  1. 01HumanNon-randomized trialEfficacy outcome

    In normal male subjects, GHRH(1-29)NH2 induced a rise in serum GH.

    In plain wordsIn healthy men, GHRH caused growth hormone in the blood to rise.

    Summary
    GHRH(1-29)NH2 induced a rise in serum GH
    1 context sentence
    Summary · context
    We have, therefore, investigated the effect of a dopamine agonist, bromocriptine, and a dopamine antagonist, domperidone, as well as a muscarinic cholinergic antagonist, pirenzepine, on the GH response to an analogue of GH-releasing hormone (GHRH) in normal male subjects.

Studies that did not test the peptide alone3

In this study, Sermorelin 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 Sermorelin.

  1. 02HumanNot a test of Sermorelin aloneNon-randomized trialMechanism

    In normal male subjects, the dopamine agonist bromocriptine augmented the GH response to GHRH.

    In plain wordsIn healthy men, bromocriptine increased the growth hormone response to GHRH.
