Findings below belong to the studies that reported them. They describe the material and conditions those authors used, not this product, and not an outcome to expect.
Schneider-Helmert D et al. · International journal of clinical pharmacology, therapy, and toxicology · 1981
The study reportedThe results suggest that DSIP in humans is also efficacious by sustaining natural sleep functions. The compound was well-tolerated and no psychologic, physiologic, or biochemical side effects were observed.
Schneider-Helmert D et al. · Experientia · 1981
The study reportedSleep-promoting effects occurred only in the second hour after injection, in the first hour a slight arousing effect was indicated. The study corroborates the findings of previous investigations in healthy subjects and shows that DSIP has a normalizing influence on human sleep regulation.
