Giusti M, Carraro A, Porcella E, Valenti S, Nicora D, Sessarego P, Giordano G · 1993 · Psychoneuroendocrinology 18:79-84
Reported findings and study design
DSIP did not change spontaneous or arginine-stimulated growth hormone or prolactin secretion. The placebo-comparison subset comprised three women.
Dose, route and schedule
In the three-woman circadian comparison, DSIP 25 micrograms/kg intravenously from 21:30 to 22:30 versus placebo infusion. Historical study methods, not personal-use instructions.

| Placebo-comparison subset | 3 women | 8 women participated across all experiments |
Five other women underwent arginine challenge conditions; eight is not the placebo-comparison sample size. Randomization and masking are not stated in the abstract.
