About DSIP

Delta sleep-inducing peptide (DSIP) is a nonapeptide first isolated from rabbit cerebral venous blood in 1977 and studied since as a candidate sleep-modulating factor. Despite decades of research, the literature itself describes DSIP’s mechanism, and even its natural existence as a distinct signalling molecule, as unresolved. This vial ships lyophilised for reconstitution, strictly for laboratory and research use.

Third-party testing

A manufacturer's own purity figure is not independent verification. Every batch we sell is tested by an independent laboratory before it is offered.

Certificate of Analysis is on file for every batch and available on request.

What this compound has not been shown to do

We are quoting the field’s own assessment here: the 2006 review cited above is titled "a still unresolved riddle" and states plainly that DSIP’s link to sleep has never been further characterised, and that no DSIP receptor has been isolated. This is one of the least settled compounds in our catalogue, and we would rather say so than dress up the uncertainty.

Storage

Unreconstituted powder
−20 °C	24 months
2–8 °C	6 months
Room temperature	Caution — only 30 days

+30 °C	Do not use. 24 hours

Never freeze a reconstituted vial — a frozen solution is spoiled.

Reconstitution

Let the vial reach room temperature before opening — cold glass pulls condensation.
Swab the stopper. Use bacteriostatic water, or acetic acid where the compound calls for it.
Run the solvent slowly down the inside wall, never onto the powder.
Swirl gently. Do not shake — agitation shears the peptide.
Let it stand 5–10 minutes until fully in solution before drawing.
Refrigerate at 2–8 °C immediately once reconstituted.
Never freeze it. Below 0 °C the solution is spoiled — discard the vial.
