What is DSIP?
DSIP, short for delta sleep inducing peptide, is a peptide the body makes. It is studied for sleep, stress, and pain. But this site's review found no published human trial for it, and the evidence that exists in people is limited and mixed. It is not FDA approved. In July 2026, the same US advisory panel that recommended several other peptides for compounding voted against recommending DSIP.
