  1. 01HumanRandomized controlled trialActivity measurement

    In eight subjects, the peak GH response to GHRP‑2 did not change significantly during prednisone therapy.

    Summary
    Before prednisone, peak GH levels in response to arginine and GHRP-2 were 8.8 +/- 2.8 and 80.8 +/- 21.2 microg/L. During prednisone therapy, the peak GH level in response to arginine and to GHRP-2 was 20.1 +/- 8.3 and 71.3 +/- 18.4 microg/L, respectively. The difference in peak values before and aft…

  3. 03HumanRandomized controlled trialActivity measurement

    In eight subjects, the mean area under the curve for GH release to GHRP‑2 decreased significantly with prednisone treatment (P = .04).

    In plain wordsIn eight people, the total growth hormone released after GHRP‑2 was smaller during prednisone.

    Summary
    The pattern of GH release to arginine and to GHRP-2 was not identical, and the mean area under the curve for GH release to GHRP-2 decreased significantly with steroid treatment (P = .04), suggesting that GHRP-2 acts by mechanisms additional to the removal of SRIF inhibition.
