No result from this study comes from a test of the peptide.

Studies that did not test the peptide alone3

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.

    In 76 patients with non-functioning pituitary adenoma, a lower peak GH release during a GHRP‑2 test was associated with more anterior pituitary hormone deficiencies.

    In plain wordsIn 76 patients with pituitary tumours, a lower peak growth hormone on a GHRP‑2 test went with more missing pituitary hormones.

    Summary · context
    Among the 76 patients with NFPA who were admitted to our institution, 36 patients (mean age, 61 years; male/female, n = 23/n = 13) were diagnosed with severe AGHD based on a preoperative GHRP-2 test.

    After surgery, seven patients in the moderate peak GH group (M) and none in the low group (L) no longer had severe adult GH deficiency.

    Patients with low peak GH on the GHRP‑2 test were significantly older and more gonadotropin and ACTH deficient than those with moderate peak GH.
