Does DSIP actually help with sleep?
The evidence is thin and mixed. It is not a confirmed effect. This site's review found no published study in people for DSIP, even though its name and marketing are built around the idea that it brings on sleep. In July 2026 an FDA advisory panel reviewed it with other peptides and voted against recommending it for compounding. That suggests the reviewers did not see a strong case in the record either.
