DSIP research guide · Updated 24 Oct 2026
DSIP (delta sleep inducing peptide) is a nonapeptide of 9 amino acids. It was first isolated in 1977 by a Swiss research group, and named for its effect on delta wave sleep in the original animal studies. It is studied in sleep research. It is supplied as a lyophilized powder for in vitro and preclinical laboratory research only.
A good DSIP listing comes with a lab report for the exact lot in the vial. These are the results to look for:
Purity (HPLC)
How much of the sample is the compound
Identity (MS or LCMS)
Confirms it is the right molecule
Net content
The real mg in the vial versus the label
Endotoxin (LAL)
Bacterial residue, reported in EU
Sterility
Confirms nothing is growing in the vial
Heavy metals (ICP-MS)
Arsenic, cadmium, lead and mercury
Lyophilized DSIP is stable at room temperature while it ships. For long term storage keep vials at minus 20 °C. Once reconstituted for laboratory use, store at 2 to 8 °C and use within 30 days.
DSIP sits in the cognitive and sleep research area with Selank and Semax.
