Double-blind rising-dose study, 12 adult male volunteers, IV boluses of 0.5-2 mcg/kg. Reports that plasma GROWTH HORMONE peaked at about 30 min and returned to baseline within 240 min "with a half-life of about 55 min". That 55 min describes the GH response curve, NOT the elimination of hexarelin, so it cannot be used as this peptide half-life. Establishes the GH response only.
