DSIP
Also known as Delta Sleep-Inducing Peptide, Emideltide.
What it is
Delta Sleep-Inducing Peptide is a nine-amino-acid peptide isolated in the 1970s from rabbit brain during slow-wave sleep. It has a long but limited human research history. It is also called Emideltide, and under that name it was the single substance the FDA's Pharmacy Compounding Advisory Committee voted not to recommend in July 2026.
That is useful to know, because the compound available today as “DSIP” is the same one the committee reviewed and did not recommend under its other name.
