How to Store DSIP: Temperature, Shelf Life & Handling
Storage requirements for DSIP follow from what the molecule actually is — nonapeptide (9 residues), strongly acidic. The conditions below reflect that chemistry rather than generic peptide guidance.
In plain English
Freezer for the powder, fridge once mixed, two to three weeks of use. Darkness is not optional here. It carries a tryptophan at the exposed end of the molecule, and tryptophan is the single most light-sensitive amino acid there is.
What DSIP actually is
DSIP stands for Delta Sleep-Inducing Peptide. It was isolated in the 1970s from the blood of animals in deep sleep — its name records how it was discovered, not a settled explanation of what it does. Decades on, researchers still have not agreed on its mechanism.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

Storage conditions for DSIP
Why these conditions, specifically
DSIP combines two independent liabilities — a photo-labile N-terminal residue and an Asp-Ala isomerisation site. It rewards careful storage more than most short peptides.
The main route to be aware of: tryptophan photo-oxidation — the characteristic route for this sequence, and the reason light protection is not optional here.
All 3 degradation routes for DSIPFreeze–thaw
Aliquot on reconstitution. Freeze–thaw cycling of an acidic peptide solution also risks local pH shifts as buffer components crystallise at different rates.
What DSIP is studied for
Investigated for effects on slow-wave sleep in the models that gave the peptide its name.
Studies have examined interactions with stress-axis signalling.
Explored in preclinical models of oxidative and stress-related neuronal injury.
Notably, decades of work have not converged on an accepted receptor or mechanism — a recurring theme in the literature.
