  1. 01HumanNon-randomized trialEfficacy outcome

    In protracted critically ill patients, the GH response to GHRP‑2 was supranormal and higher in women than in men.

    In plain wordsIn patients with long critical illness, GHRP‑2 caused a higher GH response in women than in men.

    Summary
    GH responses to GHRP-2 in women (93+/-38 microg/L) were supranormal and higher (P<0.0001) than those in men (28+/-16 microg/L).

    Summary · context
    In a second study, GH responses to GHRH (1 microg/kg), GH-releasing peptide-2 (GHRP-2; 1 microg/ kg) and GHRH plus GHRP-2 (1 and 1 microg/kg) were examined in comparable, carefully matched male (n = 15) and female (n = 15) patients.

Studies that did not test the peptide alone1

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 aloneNon-randomized trialEfficacy outcome

    In protracted critically ill patients, combining GHRH with GHRP‑2 removed the gender difference in the GH response.

    In plain wordsIn patients with long critical illness, GHRH plus GHRP‑2 together gave similar GH responses in men and women.

    Summary
    Combining GHRH with GHRP-2 nullified this gender difference (77+/-58 in men vs. 120+/-69 microg/L in women; P = 0.4).
