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

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. 01HumanNot a test of Sermorelin aloneNon-randomized trialEfficacy outcome

    In six healthy men, oral pyridostigmine augmented the growth hormone response to intravenous GHRH(1-29)NH2 by more than the additive effect of each agent alone.

    In plain wordsIn six healthy men, the drug pyridostigmine made the growth hormone response to a GHRH injection larger than the two agents added together.

    Summary
    In six healthy male adult volunteers 120 mg oral pyridostigmine increased basal GH secretion compared to placebo and augmented the GH response to 100 micrograms i.v. GHRH (1-29) NH2; the effect was more than the additive effect of pyridostigmine and GHRH when each was given alone.

    In this study, Sermorelin was a lab tool or a carrier, part of a mix, or the subject of a lab method. This result is not evidence about taking Sermorelin.

    In healthy men, pretreatment with methionyl-hGH abolished the serum GH response to GHRH given 3 h later.

    In plain wordsIn healthy men, a prior growth hormone dose removed the growth hormone response to a later GHRH injection.

    In healthy men, pyridostigmine restored the GH response to GHRH that methionyl-hGH pretreatment had inhibited.

    In plain wordsIn healthy men, pyridostigmine brought back the growth hormone response to GHRH that a prior growth hormone dose had blocked.

    Summary
    this inhibited response to GHRH was restored in subjects given pyridostigmine as well as methionyl-hGH.

    In this study, Sermorelin was a lab tool or a carrier, part of a mix, or the subject of a lab method. This result is not evidence about taking Sermorelin.
