DSIP is one of the most intriguing peptides within sleep and neuro research. In this guide we explain, research-only, what DSIP is, where the name comes from and within which research themes it is studied — without any sleep or health claims.
DSIP (Delta Sleep Inducing Peptide) is a nonapeptide from research into sleep and delta brain waves, studied in relation to sleep regulation and stress. It is not a medicine and is offered for research only, ≥99% pure with a COA per batch.
What is DSIP?
DSIP is a nonapeptide — a chain of nine amino acids — that was originally isolated from research into sleep and delta brain waves. It is one of the classic “neuropeptides” that has appeared in the literature for decades. New to peptides? First read what peptides are.
Where the name DSIP comes from
DSIP stands for Delta Sleep Inducing Peptide; the name refers to the research context in which it was first described. Delta waves are the slowest brain waves, characteristic of deep sleep. The peptide was named after that phenomenon — a name from research history, not a description of a guaranteed effect.
What is DSIP studied for in research?
In research DSIP is associated with sleep regulation and with the body's response to stress. It is a recurring object of study within neuro-endocrinology. These descriptions come from preclinical research and are no proof of effect in humans. Within the same research direction, Selank and Epithalon are also studied.
How is DSIP reconstituted?
DSIP is supplied as a lyophilised powder and reconstituted in the lab with bacteriostatic water. Determine the right ratio with the reconstitution calculator, or read how to reconstitute peptides.
Purity and documentation
Reproducible neuro research requires material with verified purity and full traceability. Every batch of DSIP at Peptide Lab is tested by Janoshik Analytical at ≥99% purity by HPLC and mass spectrometry, with a public certificate per lot number.
