To investigate the suppressive effect of somatostatin on growth hormone secretion, a consistent, potent stimulus to growth hormone release is required. The antilipolytic compound 3,5-dimethylpyrazole (DMP) gave a rapid rise in plasma immunoreactive growth hormone following iv administration to fasting
