    In 10 adult male volunteers, a 10 micrograms intravenous bolus of GHRH(1-29)NH2 produced a significantly higher peak GH than saline.

    In plain wordsIn 10 healthy men, a 10 microgram injection of GHRH(1-29)NH2 raised peak growth hormone more than saline did.

    Summary
    Compared with saline, both 10- and 100-micrograms GHRH(1-29)NH2 doses (but not 1 microgram) resulted in significant peak GH responses (means and 95% confidence intervals: 24.03 (11.22-51.29) vs 26.09 (16.40-41.50) mU/l, respectively).
