  1. 01HumanRandomized controlled trialMechanism

    In prolonged critically ill patients, GHRP‑2 infusion, but not GHRH or TRH, markedly synchronized GH, TSH and PRL serum profiles versus placebo.

    In plain wordsIn patients with long critical illness, GHRP‑2 made growth hormone, TSH and prolactin release move together, compared with placebo.

    Summary
    Infusion of GHRP-2, but not GHRH or TRH, markedly synchronized serum profiles of GH, TSH and PRL (all P< or =0.007).

    Summary · context
    obtained from prolonged critically ill patients by nocturnal blood sampling every 20 min for 9 h during 21-h infusions of either placebo (n=22), GHRH (1 microg/kg/h; n=10), GH-releasing peptide-2 (GHRP-2; 1 microg/kg/h; n=28), TRH (1 microg/kg/h; n=8) or combinations of these agonists (n=8).

Studies that did not test the peptide alone2

In this study, GHRP-2 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 GHRP-2.

  1. 02HumanNot a test of GHRP-2 aloneRandomized controlled trialMechanism

    In prolonged critically ill patients, adding GHRH to GHRP‑2 infusion kept only GH and PRL synchrony (P=0.003), more marked than with GHRP‑2 alone.

    In plain wordsIn patients with long critical illness, GHRH plus GHRP‑2 kept only growth hormone and prolactin in step, more than GHRP‑2 alone.

    Summary
    After addition of GHRH and TRH to the infusion of GHRP-2, only the synchrony between GH and PRL was maintained (P=0.003 for GHRH + GHRP-2 and P=0.006 for TRH + GHRH + GHRP-2), and was more marked than with GHRP-2 infusion alone (P=0.0006 by ANOVA).
