    Summary
    Hexarelin induced a higher increase in GH levels as compared to GHRH (integrated output calculated as area under the curve AUC0-120 4,693 +/- 691 vs. 1,494 +/- 102 micrograms.min/l, p < 0.01).

    Summary · context
    In a first experiment conducted on 6 healthy male volunteers, we studied the interaction of the maximally effective intravenous dose of hexarelin (2 micrograms/kg i.v.) with GH-releasing hormone (GHRH, 2 micrograms/kg i.v.) and somatostatin (2 micrograms/kg/h i.v.).

Studies that did not test the peptide alone2

In this study, Hexarelin 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 Hexarelin.

  1. 02HumanNot a test of Hexarelin aloneNon-randomized trialEfficacy outcome

    In healthy men, coadministration of hexarelin and GHRH produced a higher GH response than hexarelin alone.

    In plain wordsIn healthy men, hexarelin together with GHRH raised GH more than hexarelin alone.

    Summary

    In healthy men, somatostatin infusion blunted but did not abolish the GH response to hexarelin.

    In plain wordsIn healthy men, somatostatin reduced the GH rise caused by hexarelin but did not stop it.

    Summary
    Somatostatin abolished the GH response to GHRH (AUC0-120 363 +/- 89 micrograms.min/l, p < 0.01), while it only blunted that to hexarelin (AUC0-120 1,314 +/- 297 micrograms.min/l, p < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
