Certificates of analysis
Each certificate covers one production run, and reports on that batch alone. Open any of them to read the laboratory report exactly as the third-party lab issued it.
Authenticity
Scan the code on the label to pull up every published certificate for that compound — the same reports the third-party laboratory issued, batch by batch. Traceable from the laboratory that tested it to your bench.
Verify a batch →Independently tested
Purity is quantified by reverse-phase HPLC and identity confirmed by mass spectrometry, by an outside laboratory rather than in-house.
A certificate for your lot
The report that ships with your order describes the batch you received — not the product line, and not a representative sample.
COA-backed replacement
If material does not match the certificate issued for its lot, we replace it or refund it. Send us the lot number and we will trace it.
Tracked dispatch
Tracking is issued when the label is created, so the shipment is traceable from the moment it leaves us.
About this compound
C₃₅H₄₈N₁₀O₁₅
Delta sleep-inducing peptide is a nine-residue sequence first isolated in 1977 from blood drawn during slow-wave sleep — which is how it earned the name. Subsequent work has been broad rather than deep, examining sleep architecture, stress-axis signaling and hormone regulation across a range of models, without a single dominant mechanism emerging.
Full specification
How it works
The pathways DSIP acts on, and what each one does. Signalling described from preclinical models.
Neurotransmitter Modulation
Reported effects span several transmitter systems rather than one, which is part of why no single mechanism has settled. The literature is broad rather than deep.
Sleep Architecture
The peptide was isolated from blood drawn during slow-wave sleep, and delta-wave activity remains the endpoint most often measured. That origin is also where the name comes from.
Stress & Neuroprotection
Work on stress-axis signalling and neuroprotective endpoints sits alongside the sleep research, generally in the same rodent models rather than as a separate line of enquiry.
Uses & applications
The main areas under study, and the study-reported figures behind them.
Delta-wave activity is the endpoint, which follows from the peptide being isolated from blood drawn during slow-wave sleep.
HPA-axis endpoints are measured alongside the sleep ones, generally within the same rodent protocols rather than separately.
Oxidative-stress models measure neuronal survival. This is the smallest of the three areas and the least replicated.
What the published work measures
The endpoints reported across the literature for this compound. The figures belong to the individual papers, not to us.
Molecular structure
A computed low-energy conformer built from this compound's published connectivity and stereochemistry, paired with its verified reference values.
Drag to rotate
108 atoms
108 atoms, 109 bonds, C35H48N10O15. Connectivity and stereochemistry from PubChem CID 68816. The arrangement is one computed low-energy conformer, not a measured structure — a flexible peptide adopts many conformations in solution.

FAQ
Delta sleep-inducing peptide is a nine-residue sequence first isolated in 1977 from blood drawn during slow-wave sleep — which is how it earned the name. Subsequent work has been broad rather than deep, examining sleep architecture, stress-axis signaling and hormone regulation across a range of models, without a single dominant mechanism emerging.
Published research on DSIP concentrates on Sleep Architecture, Stress Adaptation and Neuroprotection. Each of those areas is summarised further up this page with the citation it comes from, and the full reference list — 3 indexed publications — sits at the bottom. Study designs and concentrations vary considerably between publications, so the primary sources are worth reading directly.
The literature describes DSIP acting across Neurotransmitter Modulation, Sleep Architecture and Stress & Neuroprotection, reported respectively as Neuromodulator, Delta Sleep ↑ and Neuroprotective. Those pathways are drawn from preclinical models rather than clinical work, and they describe what has been observed rather than a settled mechanism — the individual pathway cards above cite what each one is based on.
DSIP has a molecular formula of C₃₅H₄₈N₁₀O₁₅ and an average mass of 848.8 g/mol. It is indexed under CAS 62568-57-4. It ships as white lyophilized powder. Those are nominal reference values for the parent compound. The identity of the specific material you receive is confirmed by mass spectrometry and reported on that lot's certificate.
Store the sealed vial at Store at -20°C, protected from light, protected from light and moisture, and let it reach room temperature before opening so condensation does not form on cold powder. Keep reconstituted solution refrigerated and avoid repeated freeze-thaw cycles — solutions are far less stable than lyophilized powder.
No. DSIP is supplied strictly for in-vitro laboratory research and development. It is not a drug, food, supplement or cosmetic, it has not been evaluated by the FDA, and it is not intended for human or animal consumption, ingestion, injection or any in-vivo use. Ordering confirms you are a qualified researcher or institution purchasing on that basis.
