What DSIP is
DSIP is a nonapeptide. A nine-amino-acid peptide first isolated from rabbit cerebral venous blood, studied for delta-wave sleep architecture and stress-axis modulation.

Where it sits
Incretin compounds are grouped by how many receptors they act at. A single agonist works at GLP-1 alone, a dual agonist adds GIP, and a triple agonist adds glucagon. The receptor count is the clearest way to tell one from another when the names are unfamiliar.
Other names
DSIP is also written as Delta Sleep-Inducing Peptide. The same molecule appears under more than one name, which is worth knowing when comparing listings between suppliers.
Others in the metabolic and GLP-1 range
DSIP sits in the metabolic and GLP-1 group. The compounds below share that grouping, which is the useful starting point when comparing one against another: same group means the comparison is like for like, different group usually means it is not.
