  1. 01HumanRandomized controlled trialEfficacy outcome

    Independent of estradiol status, postmenopausal women had a lower GH response to GHRP‑2 than premenopausal women (P < 0.001).

    Summary
    Independently of E(2) status, POST women had lower GH responses to both GHRH (P = 0.028) and GHRP-2 (P < 0.001) than PRE women.

    Summary · context
    To this end, healthy PRE (n = 20) and POST (n = 22) women underwent a low- vs. high-E(2) clamp before receiving a continuous intravenous infusion of GH-releasing hormone (GHRH) or GH-releasing peptide (GHRP-2).
  2. 02HumanRandomized controlled trialEfficacy outcome

    Independent of age, GHRP‑2 was more stimulatory of GH than GHRH during low estradiol (P = 0.011).

    In plain wordsAt low estradiol, GHRP‑2 raised GH more than GHRH did.
